Chapter 2Introduction

The Harmonic DiviCom Electra 5400 MPEG-4 AVC Standard Definition Multiservice Encoder series uses the MPEG-4 Part 10 (AVC), also known as ITU-T H.264, standard to compress its video inputs. It accepts up to four standard definition (SD) video inputs, and up to ten stereo pairs of analog or digital audio inputs. The encoder output is MPEG-2 Transport Stream (TS) transmitted over IP transport.

This chapter describes:

General features

Video encoding features

Audio encoding features

Support for AVC, DiviTrackIP, DPI, and HHP

The front and back panels

2.1 Operating EnvironmentThe encoder operates under the control of NMX Digital Service Manager or in standalone mode using Configuration Manager. NMX manages multiple DiviCom Electra 5400 encoders and other devices. NMX provides full configuration of the DiviCom Electra 5400 platform, ports, services, and PSI, as well as alarm management. You configure a few initial network settings from the front panel of the encoder. The encoder operates within an IP environment; therefore, encoders and multiplexers do not need to be in the same physical location. Harmonic recommends discussing your planned network architecture with a Harmonic representative before implementation.

2.2 General Features Table 2-1 describes general features supported by the Electra 5400. See the following tables for more information about video and audio compression.

NOTE: Internal Electra encoder audio boards only support one audio codec at a time. The three pairs of audio channels must use AC-3, MPEG2, or AAC audio, not a mixture of both. If more than one codec is required you must use an AIC card. Passthrough can be conducted on any codec. For example, you can do MPEG L2 compression on the first pair and AC3 passthrough on the second pair.

of bits on a frame-by-frame basis, driven by picture complexity information from the LookAhead analysis. By assigning priorities, you can specify channels that must maintain a high quality when stress on the system increases.

NOTE: DiviTrackIP is not supported on BNG multiplexers.

The DiviCom Electra 5400 encoder works in conjunction with NMX and a ProStream 1000 to support DiviTrackIP. The ProStream 1000 analyzes the complexity of all incoming video streams and sends messages to the encoders through the IP network. All streams from an DiviCom Electra 5400 encoder must be sent to the same ProStream 1000.

Table 2-8 provides DiviTrack IP pool specifications. See the NMX help for information about configuring DiviTrackIP.

Maximum stream bit rate MPEG 2 encoders: 15 Mbit/sSD AVC encoders: 8 Mbit/sHD AVC encoders: 18 Mbit/s

2.8 Digital Program Insertion Support The DiviCom Electra 5400 encoder supports digital program insertion (DPI). DiviCom Electra 5400 accepts external automation system DPI commands (triggers) via Ethernet. These commands are sent via the SCTE 104 protocol, and result in the encoder placing SCTE 35 DPI messages in the outgoing MPEG Transport Stream (TS). (The DiviCom Electra 5400 also accepts commands via the SCTE DVS/525 draft protocol.)

The resulting messages carry metadata used by downstream content insertion equipment to choose and insert the proper content. When using an external automation system, that system provides the metadata values via the SCTE 104 commands. The metadata is included in the resulting SCTE 35 messages, which are placed in the outgoing MPEG Transport Stream.

DiviCom Electra 5400 also supports an internal DPI implementation that uses an SL-10 contact closure interface. The encoder uses an Omnitronix SL-10 contact closure device as a trigger. Each contact closure event triggers the DiviCom Electra 5400 to place one or more SCTE 35 messages in the outgoing MPEG transport stream. These messages comply with the CableLabs Level 1 Profile for DPI operation, and carry the following values for the these metadata fields (defined in SCTE 35):

out_of_network_indicator and duration_flag are both set. The value of the duration field in break_duration() is 0. unique_program_id and splice_event_id are set to 1. avail and avail_count are set to 0.

The splicer hardware is responsible for the return to network operation after a splice event.

Chapter 2 Introduction HHP Support


NOTE: Operation under the CableLabs Level 1 profile has been deprecated by SCTE DVS in the adoption of SCTE 118-2.

2.9 HHP Support Harmonic Heartbeat Protocol (HHP) is a proprietary Harmonic protocol used to prevent duplicate IP output after a redundancy switch and to initiate a redundancy switch in some 1x1 hot backup scenarios. HHP packets are sent over a unique multicast address on the video IP network.

In some redundancy switches, NMX may not be able to shut down the IP output from the primary device. For example, if the connection between the device and NMX is lost, NMX issues a time-out alarm for the device and provisions the backup device with the circuits from the primary device. However, the primary device may still be operating normally even though it lost communication with NMX. In this case, you now have two devices sending the same output.

To prevent this scenario, enable HHP. When you enable HHP, a backup device taking over in a redundancy switching event will send a command (over a unique multicast address on the video IP network) to turn off the outputs of the formerly active device. During a redundancy switch, the backup device assumes all responsibilities of the primary device, including sending HHP messages at the same multicast address.

If a primary device detects HHP messages sent to its multicast IP address, it immediately backs off and stops sending output. This leaves the backup device free to operate without the primary device sending the same output.

In 1x1 hot backup configurations, the HHP protocol can also initiate a redundancy switch. In this case, the backup device monitors the primary device by listening for HHP messages. If the backup device does not detect an HHP message from the primary device during a specified interval, it initiates a redundancy switch and assumes operation as the primary device.

2.10 Closed Captions SupportThe CEA-708/608 captions include space for CEA-608 data and that the encoder can receive them either via serial port (SMPTE 333M compliant, one service per chassis) or in VANC (SMPTE 334-1 compliant, one service per encoder mounted).

These captions are placed into the video elementary stream per either ATSC or North American DBS methods

2.10.1 Japanese Standard Closed-Captions SupportThe Electra 7000 provides support for Japanese standard captions as well as the existing support for CEA-708 captions via SMPTE 333 and SMPTE 334-1 inputs. The Electra 7000 encoder supports the closed-caption feature where the closed-caption data is generated within the ancillary data space and is extracted by the encoder for processing. The Vertical Ancillary Data Space (VANC) packets adhere to the ARIB STD-B37 standard (Structure and Operation of Closed Caption Data Conveyed by Ancillary Data Packets).

2.11 Front Panel Figure 2-1 shows the front panel of the DiviCom Electra 5400 encoder.

Chapter 2 Introduction Front Panel


Figure 2-1: Front panel

2.11.1 Front Bezel The encoder has a detachable front bezel that snaps on top of the local control panel and provides access to the reusable air filters. See 5.1 Air Filters on page 37 for information about cleaning the air filters.

2.11.2 Local Control Panel The local control panel allows configuration of the initial network settings for the encoder. From the front panel, you can set the encoder IP address, subnet mask, and default gateway, and view the encoder MAC address.

2.11.3 LEDs The four LEDs on the front panel indicate the operational state of the encoder. Table 2-9 describes the front panel LEDs.

Table 2-9: Front Panel LEDs

LED Color Description

Power Yellow The Power LED is yellow while the encoder initializes after startup.

Green The Power LED turns green when the encoder initialization is complete and the management interface is enabled and ready.

The fuse panel is located beside the power plug. The encoder requires one slow blow 4.0 A, 250 V fuse, 5 x 20 mm. See 5.2 Fuse on page 38 for replacement instructions.

2.12.2 Audio Input Ports The Electra 5400 can be configured with a combination of onboard audio, AIC, and AHC.

2.12.2.1 AIC Adapter

Each AIC has two digital audio input ports (BNC connectors). The encoder supports up to five AICs. Two BNC ports support AES3 or S/PDIF to provide the stereo digital audio input to the AIC module.

Figure 2-3 illustrates the audio input ports on an AIC.

Figure 2-3: Audio input ports

2.12.2.2 AHC Adapter

The AHC has four connectors, but performs no audio processing itself. Rather, the AHC normally hosts a daughter card (RAC or 561) that performs audio compression processing. The AHC can also provide native AES inputs for onboard audio (also called the AHC-BASE). In this arrangement only three of its four connectors are used.

Four BNC ports support AES3 or S/PDIF to provide multi-channel stereo digital audio inputs to the AHC module. The daughter card is either a Harmonic RAC card or a Dolby CAT 561 card. A daughter card includes an RJ45 connector that can be used to supply Dolby audio metadata.

Figure 2-4 illustrates the ports on the AHC-RAC.

Figure 2-4: AHC-RAC digital audio input ports

NOTE: When the AHC BASE provides native AES inputs to the onboard audio, only three digital audio ports are available for use since onboard audio supports only a single 5.1 service.

Figure 2-5 illustrates the ports on the AHC-561 card.

Figure 2-5: AHC-561 digital audio input ports

Chapter 2 Introduction Back Panel LEDs


2.12.3 Video Input Ports The back panel contains up to four video input ports. These are BNC coaxial ports that support standard definition serial digital video input.

Each video input port connects internally to a video processing card (VPC) The video processing cards are not visible from the encoder back panel.

See 3.5.3 Connecting the Video Input Cables on page 29 for cabling instructions.

2.12.4 IP Output Port One 100/1000 Base-T Ethernet port provides two redundant IP output channels. The two RJ-45 connectors are labeled GbE PRI and BKUP.

The IP output port supports manual redundancy. The port also supports hot/warm standalone redundancy: when the primary IP data channel detects a cable disconnection, the primary channel stops outputting, and the backup channel takes over.

In manual redundancy, you can enable one channel or both channels. If you enable one channel, you must manually switch to the other channel after a service-affecting alarm. If you enable both channels, the encoder outputs the same data from both channels.

See 3.5.4 Connecting the IP Output Cables on page 29 for cabling instructions. Set the IP address and other network information for the IP output ports using NMX.

2.12.5 Ethernet Management Port The Ethernet management port, labeled ETH, is 10/100 Base-T and uses an RJ-45/UTP cable to connect to an Ethernet network. See 3.5.5 Connecting the Ethernet Management Cable on page 29 for cabling instructions. See A.3.1 Ethernet Management Port on page 42 for pinout information.

2.12.6 Fault Relay Port The fault relay port connects to a Form C relay that can switch up to 0.25 amps at 30 VDC. See A.3.2 Fault Relay Port on page 42 for port pinout and additional information.

The encoder energizes the fault relay during normal operation. The fault condition is indicated in the same way as the encoders powered-off condition, which is with the relay de-energized. You can use this method to correctly identify a power supply failure or loss of input power. The signals are normally open or normally closed.

NOTE: Any alarm causes the fault relay to change to the fault state. When multiple alarms accumulate, all alarms must be active for the relay state to change.

2.12.7 Serial Data Port The serial data port can be used for serial CEA-708 captions per SMPTE 333.

2.13 Back Panel LEDs The following sections describe the back panel LEDs and their functions.

The chapter describes:

How to prepare and unpack the DiviCom Electra 5400

How to install the encoder in a rack

How to update the encoder software

How to connect the cables

3.1 PreparationYou need a Phillips screwdriver to mount the encoder in a standard 19-inch rack. Harmonic ships the necessary rack-mount screws and rack rails.

3.2 Unpacking The encoder comes in a specially designed shipping container that ensures the integrity of your encoder hardware during shipping and handling. To avoid damage to the component, follow the unpacking instructions that come with the encoder.

When you unpack the encoder, you should find the following items:

Encoder

Spare air filters

Software warranty agreement

Harmonic ships rack-mounting kits in a separate shipping container.

3.3 Installing the Encoder in a Rack You can install the encoder in different sizes and types of racks. For rack assembly instructions, consult the manual that came with the rack or the customer service department of the rack manufacturer.

This section describes how to mount the encoder in a standard 19-inch rack, using the two side-mount rails included in the rack-mounting kit. A 30-inch-deep rack with a spacer or chimney between racks with multiple encoders is the recommended rack setup. However, these rails work for racks that are 30 to 36 inches deep.

When you view the rack from the rear, the power rail should be installed on the left side.

Chapter 3 Installation Installing the Encoder in a Rack


3.3.1 Rack GuidelinesWhen operating the encoder in the rack, ensure that:

The ambient temperature around the unit (which may be higher than room temperature) is within the limit specified for the unit.

There is sufficient airflow around the unit.

Electrical circuits are not overloaded; consider the nameplate rating of all the connected equipment.

There is overcurrent protection.

The equipment is properly grounded.

No objects are placed on top of the unit.

3.3.2 Chassis Warnings for Rack Mounting and Servicing

CAUTION: To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety.

This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

If the rack will hold a number of units, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

ATTENTION: Pour viter toute blessure corporelle pendant les oprations de montage ou de rparation de cette unit en casier, il convient de prendre des prcautions spciales afin de maintenir la stabilit du systme. Les directives ci-dessous sont destines assurer la protection du personnel.

Si cette unit constitue la seule unit monte en casier, elle doit tre place dans le bas.

Si cette unit est monte dans un casier partiellement rempli, charger le casier de bas en haut en plaant llment le plus lourd dans le bas.

Si le casier est quip de dispositifs stabilisateurs, installer les stabilisateurs avant de monter ou de rparer l'unit en casier.

WARNUNG: Zur Vermeidung von Krperverletzung beim Anbringen oder Warten dieser Einheit in einem Gestell mssen sie besondere Vorkehrungen treffen, um sicherzustellen, da das System stabil bleibt. Die folgenden Richtlinien sollen zur Gewhrleistung Ihrer Sicherheit dienen.

Wenn diese Einheit die einzige im Gestell ist, sollte sie unten im Gestell angebracht werden.

Wird das Gestell mit Stabilisierungszubehr geliefert, sind zuerst die Stabilisatoren zu installieren, bevor sie die Einheit im Gestell anbringen oder sie warten.

3.3.3 Airflow The airflow through the encoder is critical for maintaining the proper temperature range. Fans in the chassis draw air in through the front bezel and through the encoder. The airflow ventilates out the right side (front view).

Chapter 3 Installation Installing the Encoder in a Rack


CAUTION: Do not obstruct the airflow of the encoder. Severe equipment damage can result when the encoder cannot properly exhaust the airflow.

3.3.4 Attaching the Rack Rails Attach the side-mount rack rails to the rack to hold the encoder in place. Figure 3-1 illustrates the parts of the rack rails.

Figure 3-1: Rack rails

To attach the rack rails to the rack:

1. If needed, place a Tinnerman speed nut with the nut on the outside of the rack over the holes to which you would like to mount the rails.

NOTE: Each of the four rack posts requires two speed nuts.

2. Position the rack rails so the shelves are toward the inside of the rack.

3. Using the #10 screws provided with the encoder, screw the mounts into the speed nuts from the inside of the rack using the rack-mount holes that line up with the holes on the rack posts.

Figure 3-2 illustrates attaching the rails.

Figure 3-2: Attaching the rails to the rack

Chapter 3 Installation Installing Encoder Software


CAUTION: Make sure to install the rack rails with the shelf at the top of the rail. If you install the rail upside down, the rail blocks the encoder air vents, which can result in overheating the encoder.

3.3.5 Mounting the EncoderTo mount the encoder in a rack:

1. Using both hands, grasp the outside corners of the plastic front bezel and slowly pull to detach it from the encoder and expose the mount holes. See Figure 3-3.

2. Gently slide the encoder to rest on the rack rails.

3. Push the encoder back until the rack-mount holes in the front of the encoder line up with the rack posts.

4. Insert four screws through the mount holes in the front of the encoder through to the corresponding holes on the rack posts.

5. Tighten the screws with a screwdriver.

6. Carefully replace the front bezel of the encoder, making sure you do not damage the air filters.

3.5.2 Connecting the Audio Input Cables An encoder may have up to five audio input cards (AICs), each of which has two stereo digital audio ports , or up to five audio host cards (AHC, AHC-RAC, or AHC-561), each of which has four stereo digital audio ports. When the encoder is equipped with an AHC-RAC used to support native AES input only three of the four digital audio ports on a card can be used at one time.

To connect the audio cables:

Connect a coaxial cable with a BNC connector from the digital audio port to the audio source. On each AIC, the digital audio ports are labeled DGTL AUD1 and DGTL AUD2. On each AHC, the digital audio ports are labeled DGTL AUD1, DGTL AUD2. DGTL AUD3, and DGTL AUD4. For multi-channel audio, use three cables to connect the surround mix, connecting L/R to DGTL AUD1, C/Lfe to DGTL AUD2, and Ls/Rs to DGTL AUD3, which maps the channels to AES3 pairs as defined by SMPTE 320M. If the encoder is equipped with an AHC-RAC, then one more stereo pair can be connected to DGTL AUD4. Otherwise the fourth connector is not used.



3.5.3 Connecting the Video Input Cables Your encoder has up to four video input ports. The video input ports accept serial digital video. To connect the video cables:

1. Connect a coaxial cable with a BNC connector from the first video source to the Video 1 port on the encoder.

2. Continue connecting the additional video sources to the remaining video ports.

3.5.4 Connecting the IP Output Cables The encoder has one IP output port with two redundant channels and two RJ-45 connectors.

NOTE: The network hosting the IP output traffic must be a different network from your management network and must be configured with a different IP address.

NOTE: Harmonic recommends that shielded and grounded Ethernet cables be used on all Ethernet ports.

To connect the IP output cables:

1. Connect an Ethernet cable from the primary IP output port to a port on a network switch or router, not a hub.

2. Optionally, connect the backup IP output port to a different switch or router to facilitate redundancy.

3. Configure the Ethernet switch to support autonegotiation by setting each port to set speed auto and set duplex auto.

NOTE: Failure to properly configure the Ethernet switch could result in a mismatch between the IP output and the switch.

Harmonic supports 10/100/1000 Base-T and is fully compliant with IEEE 802.3, 802.3u, and 802.3as standards.

3.5.5 Connecting the Ethernet Management Cable The Ethernet management port allows communication between NMX and the encoder.

To connect the Ethernet management cable:

Connect an RJ-45/UTP cable from the encoders back panel 10/100 Base-T port to a port on an Ethernet switch.

NOTE: The network hosting the IP output traffic should be a different network from your management network.

3.5.6 Connecting the AC Power The encoder AC power supply uses autosensing to adjust to different incoming voltages.

CAUTION: This product relies on the buildings electrical installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 20 A U.S. (240 VAC, 20 A international) is used on the phase conductors (all current-carrying conductors).

4.2.6 Using Configuration ManagerYou can access Configuration Manager from any computer with network access to the encoder using Microsoft Internet Explorer 6.0 or later. The Configuration Manager uses web browser cookies to maintain information.

Use Configuration Manager to:

Configure the encoder hardware, including the network settings, preferences, and port properties

Configure the audio, video, VBI or Teletext, DPI, and PSI stream properties

Configure the output program and transport properties

View current and history alarms

View the error log

TIP: You must set an IP address for the encoder before you can access Configuration Manager. See 4.2.3 Setting the Encoder Network Properties on page 32.

4.2.6.1 Preparing the Computer

Before starting Configuration Manager, you might need to do some configuration on the computer you use to access the application.

First, you must set the Internet Explorer Privacy Level to allow web browser cookies from the encoder, as the Configuration Manager uses them to track information.

NOTE: This section applies to computers running Microsoft Windows XP Service Pack 2 or later. Earlier versions of Windows do not include the pop-up blocker utility.

Microsoft Windows XP Service Pack 2 includes a utility that disables pop-up windows. By default, the utility disables pop-ups at a medium security level. Because Configuration Manager uses pop-up windows in some configuration dialog boxes, you must disable this utility or list the Ion IP address as a site that allows pop-ups.

To change the pop-up window settings:

1. Open Internet Explorer.

2. From the Tools menu, select Pop-up Blocker.

If you do not see this menu item, your version of Internet Explorer does not have this utility. You can open Ion Configuration Manager.

3. If you do have this menu item, select Turn Off Pop-up Blocker to disable the utility, or select Pop-up Blocker Settings to enable pop-ups for Configuration Manager.

4. If you selected Pop-up Blocker Settings, enter the Ion IP address in the text box under Address of Web site to allow.

5. Click Add.

The Ion IP address appears in the list of allowed web sites.

6. Click Close.

Additionally, you must set the Internet Explorer privacy level to allow web browser cookies from the encoder, as the Ion HTTP Configuration Manager uses them to track information. See the Internet Explorer help to find information about how to allow cookies.

4.2.6.2 Opening Configuration Manager

To access Configuration Manager:



1. Open Internet Explorer on a computer with network access to the encoder.

Harmonic supports Internet Explorer 6.0 and later web browsers.

2. In the Address field, type the IP address of the encoder and press Enter.

For example, enter http://192.168.24.10

The following figure shows the (SAG) Configuration Manager.

Figure 4-3: Configuration Manager Interface

Configuration Manager contains three panes:

Header pane. Across the top, this pane provides information on alarms and errors. The Rebuild PSI button calls the Rebuild PSI mechanism on the device. Click the XML button to see XML output options information.

Navigation pane. Below the status pane, on the left, this pane has two sections: The Platform section lists all cards installed on the devices. The Output Services section lists all of the output streams (audio and video). Select an item in the Platform or Output Services pane to view its properties in the Configuration pane.

Configuration Pane. Besides the Navigation pane, this is the place you can trigger actions on, and information about, items selected in the navigation pane. Use this pane to apply configuration.

You can resize any pane by dragging the border of the pane up, down, left, or right.

To begin configuring the encoder, apply a template. Templates contain basic settings for all encoder platform, port, and stream properties. After applying a template, customize the settings for your environment.

Click the Help button in the Status pane for detailed instructions for configuring the encoder.



NOTE: On PCs running Windows NT 4.0 with Internet Explorer 6.0, do not leave Configuration Manager open for extended periods of time. When Internet Explorer is left open and connected to the Configuration Manager URL, the web page continuously refreshes the alarm status display for the device, causing Internet Explorer to slowly increase its memory usage on the client PC. While this increase in memory usage does not affect the encoder, Harmonic does not recommend that Configuration Manager be open for long periods of time because it can affect other processes on the control PC.


Chapter 5Maintenance and Troubleshooting

This chapter describes:

How to maintain and replace the air filters and fuse

How to contact Harmonic Support

5.1 Air Filters The encoder uses two air filters to minimize dust and dirt in the circuitry and components in the chassis. These filters are made of flexible, compressed fiber spun from urethane foam. Installed in the front of the encoder, the filters are fire retardant and conform to UL 900 Class II specifications.

The bezel filter is located inside the front bezel, on the left side. Figure 5-1 shows the dimensions of the bezel filter. The notches on the left side and the cutouts in the middle can fit on either side of the front bezel mounting posts.

Figure 5-2: Keypad filter (front view)

5.1.1 Maintaining the Air Filters The operating environment of the encoder plays a large factor in determining the life of the air filters. Encoders that operate in dusty and dirty surroundings require more frequent inspections and filter cleaning than those operating in cleaner environments.

Inspect and clean the filters with a frequency that is appropriate to the environment in which the encoder operates. Harmonic recommends inspecting and cleaning the filters every six weeks to ensure proper airflow through the chassis.

To clean dust and dirt from the filters, you can use a vacuum cleaner to remove the dirt, or you can rinse the filters in water. You can also use soaps or mild detergents on the filters. If you rinse the filters in water, make sure that you squeeze the excess water from them before reinstalling them in the encoder. You might need to order replacement filters if the filters become too dirty over time.

Chapter 5 Maintenance and Troubleshooting Fuse


5.1.2 Removing and Replacing the Air Filters You do not need to turn off the encoder when removing and replacing the air filters.

5.1.2.1 Removing and Replacing the Bezel Filter

To remove the front left filter from behind the front bezel:

1. Grasp each side of the encoders front bezel with your hands.

2. Carefully remove the front bezel by pulling it away from the encoder.

3. Remove the filter from inside the front bezel.

4. Inspect the air filter for dirt, and clean it if necessary.

NOTE: When the filter is new, its color is medium charcoal. As dust and dirt collect in the porous filter material, the filters color gradually changes to brown, then an ash color.

5. Replace the filter inside the front bezel. Place the filter so that the long horizontal slot is at the bottom edge. Carefully place the cutouts in the filter around the bezel mounting posts.

6. Carefully replace the front bezel on the encoder making sure the filter does not fall out of the bezel.

5.1.2.2 Removing and Replacing the Keypad Filter

To remove the air filter from behind the keypad:

1. Grasp each side of the encoder front bezel with your hands.

2. Carefully remove the front bezel by pulling it away from the encoder.

Note the location of the filter. The keypad is screwed onto the front of the encoder through four mounting posts. Cutouts on the filter wrap around the four posts, and the right side of the filter extends past the keyboard.

3. Remove the filter by pulling the left side of the filter up and away from the keyboard mounting posts, then pulling up the right side.

4. Inspect the air filter for dirt, and clean it if necessary.

5. Replace the filter by inserting the right side of the filter behind the keypad, with the vertical slots around the mounting posts.

6. Insert the left side of the filter, placing the horizontal cutouts around the mounting posts.

7. Carefully replace the front bezel on the encoder making sure the filter does not fall out of the bezel.

5.2 Fuse Encoders use a slow blow 4.0 A, 250 V fuse, 5 x 20 mm. The fuse is located on the back panel beside the power input. A spare fuse is located in the fuse cover, shown in Figure 5-3.
