4.4 OPERATING MODES

4.4.1 Mode "ON LINE" (INVERTER MODE)

The ON-LINE-Mode is the UPS-Operating Mode in which the load is supplied through theRECTIFIER and INVERTER.

Using the control panel (see figure 4.1), the UPS can easily be transferred to the ON-LINE-Mode.The ON-LINE-Mode provides the highest degree of protection, especially in the event of a mainsdisturbance or failure.

This operating mode is always recommended if the critical loads (computer systems) will nottolerate any interruption of the supply (not even the shortest).

In the unlikely event of an inverter fault or overload condition the UPS will transfer the loadautomatically and without interruption to the static bypass-mains supply (transfer time = 0).

4.4.2 Mode"OFF-LINE"(ECO- or BYPASS MODE)

In the "OFF-Line Mode”, the load is supplied from the mains through the static bypass.

Using the control panel (see figure 4.1), the UPS may be easily transferred to "Bypass Mode”.

When the UPS is operating in "Bypass Mode”, the efficiency of the system is higher. In the eventof a mains failure the load will automatically be transferred from mains to inverter within 5 msec(this is valid for single and parallel systems). The battery charger remains active in the "Bypass-Mode”.

The "Bypass-Mode”, is recommended only if the loads can tolerate interruptions of 3-5 ms(transfer time from Bypass Mode to ON-LINE Mode).

In order to provide the load with maximum protection RITTAL alwaysrecommends that the load be supplied by the inverter (ON-LINE-Mode).!

Before transferring the load to Maintenance Bypass (IA1) always make sure allthe UPS-modules are in the "Bypass-Mode” or “ECO-Mode”.

IF THE UPS IS OPERATING IN THE MAINTENANCE BYPASS MODE THROUGHTHE BYPASS SWITCH THE LOAD WILL NOT BE PROTECTED IN THE EVENTOF A MAINS FAILURE. IT IS THEREFORE STRONGLY RECOMMENDED TOSWITCH OVER TO THE ON-LINE MODE (INV. ON) OR BYPASS MODE (OFF-LINE MODE) AS SOON AS POSSIBLE.

4.4.4 Parallel Isolator (IA2)

Every UPS-unit (module) is provided with an output parallel isolator (IA2) which, when openedisolates the corresponding unit (module) from the PARALLEL BUS and from the LOAD. Once IA2is open there is no power coming from its inverter.

In redundant parallel configurations it is used to isolate a unit from the parallel system without theneed of transferring the load to bypass.

6 Multi-Cabinet Configuration

6.1 CONCEPT OF MULTI-CABINET CONFIGURATION

The PMC Extended Twin-Cabinets may be paralleled for power capacity PMC Basic or forredundancy indefinitely. Every standard PMC is provided with the parallel option and therefore notime-consuming upgrading is necessary on site.

UPS 1 UPS 2 UPS n

Fig. 6.1. PMC Extended Twin Multi-Cabinet Chain.

The Multi-Cabinet Chain is based on a decentralised bypass architecture i.e. every UPS isprovided with its own static bypass. In a parallel system there is always one Master Module andthe other Modules are slaves. If at any time the master is faulty the next UPS (former slave) willimmediately take over the master function and the former master will switch off.

Every UPS unit in a parallel configuration is provided with a proper output parallel Isolator (IA2)which, when opened isolates the corresponding unit from the parallel system. Once the parallelisolator (IA2) of a unit is open that unit (module) is isolated from the rest of the parallel systemand therefore does not provide power to the output.

For example if you perform the command “LOAD TO BYPASS” on any unit, all the units willtransfer the load simultaneously to mains and if you perform the command “LOAD TOINVERTER” on any unit all the UPS’s will simultaneously transfer the load to the inverters.

The PMC is paralleled for redundancy (highest availability) or for power parallel systems.

IMPORTANT: The BYPASS MODE (ECO-MODE) function of a parallel systems is the sameas in single units of PMC. If in a parallel UPS system the load is transferred to the BYPASS (loadon mains) and if the mains fails, the UPS’s will all be automatically transferred to inverter within5msec.

In order to provide the load with maximum protection RITTAL alwaysrecommends that the load be supplied by the inverter (ON-LINE-Mode).!

6.2 INSTALLATION INSTRUCTIONS

6.2.1 Introduction

ELECTRICIANS OR BY QUALIFIED INTERNAL TRAINED PERSONNEL.

BY OPENING OR REMOVING THE UPS-MODULES AND MODULE COVERSYOU RUN RISK OF EXPOSURE TO DANGEROUS VOLTAGES!

BEFORE REMOVING A UPS-MODULE MAKE SURE THE INTERNAL DC-CAPACITORS HAVE BEEN DISCHARGED FOR AT LEAST 2 MINUTES.

DO NOT EVER LEAVE THE UPS-MODULE COMPARTMENT WITHOUT ANAPPROPRIATE PROTECTION COVER.

RITTAL WILL NOT TAKE RESPONSIBILITY OR BE LIABLE FOR PERSONNELINJURIES OR MATERIAL DAMAGES CAUSED BY IMPROPER MANIPULATIONOF THE UPS, OR BY INCORRECT CABLING. THE PROPER INSTALLATION ANDUSAGE INSTRUCTIONS OF THE UPS ARE DESCRIBED WITHIN THIS MANUALAND MUST BE STRICTLY ADHERED TO.

DO NOT ATTEMPT TO COMMISSION A PARALLEL CABINETS SYSTEMWITHOUT CAREFULLY READING THIS USER MANUAL (SEE ALSOCHAPTERS 3 AND 4

NOTE: IN ORDER TO ACHIEVE EQUAL LOAD SHARING BETWEEN THE UPS-CABINETS, THEINPUT CABLE LENGTHS FROM THE INPUT DISTRIBUTION BOARD TO THE UPS AND FROM THEOUTPUT CABLE TO THE OUTPUT DISTRIBUTION BOARD SHOULD BE THE SAME RESPECTIVELY.WHEN CABLING THE UPS’S BEWARE TO CONNECT INPUT AND OUTPUT WIRES TO THECORRESPONDING TERMINALS, RESPECTING THE SAME PHASE SEQUENCE ON ALL UPSCABINETS. EXAMPLE: PHASE1 UPS1 = PHASE1 UPS2 = …… = PHASE1 UPS n

WHEN CABLING THE UPS’s MAKE SURE THAT THE UPS’s ARECOMPLETELY VOLTAGE FREE. CHECK THAT THE MAINTENANCEBYPASSES (IA1) AND ALL PARALLEL ISOLATOR (IA2) ARE OPEN (“OFF”) ONALL CABINETS.

6.2.2 Paralleling of UPS-Cabinets

6.2.2.1 Connection of Parallel Communication Cables (BUS-lines)

For the correct performance of different parallel functions and operations the parallel unitscommunicate continuously between each other. This is achieved by means of the so-calledcommunication BUS-Lines.

After terminating the input and output cabling of each single UPS, it is necessary to connect theunits together to form the parallel system. For this purpose a communication BUS line isconnected sequentially between the units. Connect communication BUS lines according to Figure6.2.

NOTE: CONNECT THE BUS CABLES ONLY WITH SWITCHED OFF UPS AND OPENEDPARALLEL ISOLATORS IA2. RESPECT THE FOLLOWING CONNECTION SEQUENCES.

1. Fit the Parallel Adapter over the Connector JD8 on all UPS-cabinets

2. Set DIP Switch SW2-2 on each Parallel Adapter depending on the UPS Cabinet in theparallel cabinet configuration (see page 45)

3. Connect PORT JD6 on Parallel Adapter of UPS-Cabinet 1and PORT JD5 of ParallelAdapter of UPS-Cabinet 2 with the corresponding BUS-Cable;

4. Connect PORT JD6 on Parallel Adapter of UPS-Cabinet 2 and PORT JD5 of UPS-Cabinet 3 with the corresponding BUS-Cable

5. Continue in the same manner for the remaining UPS-Cabinets.

Before starting up the parallel system it is necessary to set the DIP Switches SW1-1 and SW1-9to their correct positions.

DIP Switch SW1-1

The DIP Switch SW1-1 is located on every UPS-Module and serves to define if the UPS-Moduleis a single or parallel Module.

SW1-1 has two positions:

HIGH = Parallel (the Module is in a parallel system)

LOW = Single (the Module is a single UPS)

In the case of parallel cabinet configurations the SW1-1 on all Modules is always in position HIGH= Parallel.

DIP Switch SW1-9

The DIP Switch SW1-9 is located on every Cabinet (PMC Extended Twin) and not on Modules.With this switch it is possible to determine the “position of an PMC Extended Twin-Cabinet” ina Multi-Cabinet Chain. Define each PMC Extended Twin-Cabinet in a Multi-Cabinet Chain as:

1. The “First”,

2. The “Middle” (there may be more than one) and

3. The “Last”

Cabinet in the Multi-Cabinet Chain by setting the DIP Switch SW1-9 on each cabinet according tothe Table below:

After having set the SW1-1 on all UPS-Modules and SW1-9 on all the PMC Extended Twin-Cabinets correctly the UPS’s may be commissioned

6.2.4 ON/OFF – Main Buttons

The ON/OFF-Buttons serve to shutdown the UPS-system for service or maintenance or foremergency reasons.

IF BOTH ON/OFF-BUTTONS ARE PRESSED ON THE UPS-Module IN A MULTI-Module SYSTEM ONLY THAT PARTICULAR UPS-Module WILL SHUTDOWN.TO SHUTDOWN THE COMPLETE SYSTEM PRESS BOTH ON/OFF-BUTTONSON EVERY UPS-MODULE OF A MULTI-MODULE SYSTEM .

6.2.5 Parallel Isolator (IA2)

Every UPS-unit is provided with a parallel isolator IA2. The parallel isolator is an importantelement of the UPS-unit, that allows the isolation of a unit from the parallel system without theneed to transfer the load to bypass.

IA2 OPEN: THE CORRESPONDING UPS-MODULE IS ISOLATED FROM THEOUTPUT. THERE IS NO COMMUNICATION BETWEEN THE ISOLATED UNIT ANDTHE REST OF THE PARALLEL SYSTEM. THE ISOLATED UPS-MODULE MAY BEREPLACED WITHOUT COMPROMISING THE REST OF THE SYSTEM.IA2 CLOSED: THE CORRESPONDING UPS IS BEING ADDED TO THE REST OFTHE PARALLEL SYSTEM.IMPORTANT: BEFORE CLOSING THE IA2 OF A UPS-MODULE BE SURE THATTHE STATUS OF THAT UPS-MODULE IS THE SAME AS OF THE REST OF THEOPERATING UPS-MODULE WITH CLOSED IA2. EXAMPLE: IF ALL UPS’s WITHCLOSED IA2 ARE ON INVERTER, MAKE SURE THAT THE UNIT ON WHICHISOLATOR IA2 IS BEING CLOSED IS ALSO ON INVERTER.

6.2.6 Maintenance Bypass (IA1)

There are two types of Parallel System Configurations: redundant and capacity parallel systems(see Chapter 5).

!

!

A3346302IT74-GB 46

6.2.6.1 Redundant Parallel Configuration

In a redundant parallel system a UPS-module may easily be isolated from the parallel system byopening the respective isolator (IA2). It is now possible to operate or shut down this unit withoutinfluencing the rest of the parallel system. The rest of the parallel system will continue to protectthe load. The isolated UPS-Module may be replaced without the need of transferring the load tobypass by means of the Maintenance Bypass (IA1).

6.2.6.2 Capacity Parallel Configuration

In the event of a fault in one of the UPS-Modules in a capacity parallel system the load willautomatically be transferred to static bypass (mains). In order to replace the faulty module theload must be transferred to mains by means of Maintenance Bypass (IA1).

6.2.7 ECO-MODE (BYPASS MODE) in Parallel Systems

The Eco-Mode function in a Parallel System is the same as in Single Systems. If in a PMCParallel System the load is supplied by the mains(load on mains) and in the event of mainsfailure, all UPS’s will automatically transfer the load back to the inverters with 5msec.

In order to provide the load with maximum protection RITTAL alwaysrecommends that the load be supplied by the inverter (ON-LINE-Mode).

6.3 COMMISSIONING OF MULTI-CABINET CONFIGURATION

ALL THE OPERATIONS IN THIS SECTION MUST BE PERFORMED BYAUTHORISED ELECTRICIANS OR BY QUALIFIED INTERNAL TRAINEDPERSONNEL.BY OPENING OR REMOVING THE UPS-MODULES AND MODULE COVERS YOURUN RISK OF EXPOSURE TO DANGEROUS VOLTAGES!BEFORE REMOVING A UPS-MODULE MAKE SURE THE INTERNAL DC-CAPACITORS HAVE BEEN DISCHARGED FOR AT LEAST 2 MINUTES.DO NOT EVER LEAVE THE UPS-MODULE COMPARTMENT WITHOUT ANAPPROPRIATE PROTECTION COVER.RITTAL WILL NOT TAKE RESPONSIBILITY OR BE LIABLE FOR PERSONNELINJURIES OR MATERIAL DAMAGES CAUSED BY IMPROPER MANIPULATION OFTHE UPS, OR BY INCORRECT CABLING. THE PROPER INSTALLATION ANDUSAGE INSTRUCTIONS OF THE UPS ARE DESCRIBED WITHIN THIS MANUALAND MUST BE STRICTLY ADHERED TO.

7 Maintenance

7.1 INTRODUCTION


To ensure an optimum operation of the PMC and a continuous and efficient protection of theconnected load it is recommended to check the batteries every 6 months, depending on theambiance temperature.

7.2 USER RESPONSIBILITIES

There are no user serviceable parts contained within the UPS so the maintenance responsibilitiesof the user are minimal. To maximise the useful working life and reliability of the UPS and itsbatteries, the environment in which the UPS operates should be kept cool, dry, dust and vibrationfree. The batteries should be hold fully charged.

7.3 ROUTINE MAINTENANCE

The UPS is designed to receive regular preventative maintenance inspections. Thesepreventative maintenance inspections are essential to ensure that both the useful working life andthe reliability of the UPS are maximised. When the UPS is commissioned, the commissioningfield service engineer will attach a service record book to the front of the UPS and this will beused to record the full service history of the UPS.

Preventative maintenance inspections involve working inside the UPS, which contains hazardousAC and DC voltages. Only RITTAL trained or agreed service personnel and authorised fieldservice engineers are fully aware of all of the hazardous areas within the UPS.

During a preventative maintenance inspection the field service engineer will carry out thefollowing checks:

• Site/environment conditions;

• Integrity of electrical installation;

• Cooling airflow;

• Rectifier operation and calibration;

• Inverter operation and calibration;

• Static switch operation;

• Battery status;

• Load characteristics;

• Integrity of alarm and monitoring systems;

• Operation of all installed options;

7.4 BATTERY TEST

The battery test takes approx. 3 minutes and should be performed only if:

• there are no alarm conditions;

• the battery is fully charged;

• mains is present.

The battery testing can be carried out independently of the operation mode (OFF-LINE or ON-LINE) and whether or not the load is connected.

The battery test procedure can be performed from the UPS front panel. See “Operation” Chapter 4.

9.5 POWER MODULAR CONCEPT-SOFTWARE SHUTDOWN AND MANAGEMENTSOFTWARE

9.5.1 Why is UPS Management important?

By combining a UPS with network management products, such as an SNMP protocol,System-administrators are guaranteed their data and their system will constantly be protectedfrom corruption or data loss even in the event of an extended power failure or when batteriesreach a critical low state. In the event of a power disturbance system administrators can alsomonitor their network from a central location, allowing an early detection of problems. In factutility power is unreliable at times, ensuring that all network systems have constant power canbe a difficult task. The situation becomes even more complex if systems are managed acrossa Local Area Network (LAN) or Wide Area Network (WAN) around the world.

When a power failure occurs action can be taken to protect the system and its valuable data. Ifno action is initiated by the operator, this event can seriously damage the system. The UPSsoftware will react automatically in such a case and shutdown the operating system. RITTALhas found it important to have a complete solution for its UPS and is able to offer a wide rangeof monitoring/remote controls for assuring the maximum protection degree to the RITTALcustomers.

9.5.2 Power Modular Concept-Software Shutdown and Monitoring Software

Power Modular Concept PMC-Software is an external monitoring and shutdown software whichwas designed to operate with all RITTAL UPS products, both with the DRY PORT (Relays) JD2and SMART PORT (RS232) JD1.

The software packet consists of a CD ROM for most diffused operating systems (Windows,Unix, OS/2, DEC VMS, Novell, Apple), a standard connection and a user manual.

The 25 pin port with voltage-free contacts may also be used for automatic shutdown inconnection with PMC-Software. It is necessary to provide a special cable to connect the 25pin port of the UPS and the serial port of the server.

Figure 9.5. Monitoring image.

The main characteristics of PMC-Software are:

• Automatic unattended master/slave shutdown in heterogeneous networks

• On-screen autonomy time / battery time countdown

• On-screen server log off and shutdown procedure

• Extensive logging of all UPS activity and power quality data, with timestamp

• Scheduled UPS economy mode, service mode, other systems status

• Graphical user interface for Windows compatible platforms

• Automatic unattended local shutdown

A3346302IT74-GB 54

• Special software modules to close and save open MS-Office documents.

• Compatible for all optional modules like UPSDIALER, SNMP adapters,Temperature sensors, etc.

The UPS-Management Software is a client-/server-application for networks and localworkstations. Basically PMC-Software consists of two parts: the server-module of the UPS-Management Software is UPSServ, which communicates via RS-232 cable with the UPS.Working as a background process the UPSServ collects messages, received from the UPS.The UPSServ interprets received messages and makes them available to the client-moduleUPSCli and to any SNMP-based management station.

When UPSServ detects voltage variations or a power failure it can execute various so calledsystem „event routines“, which for example may shutdown the server or send warning toconnected users. These system event routines which are a part of the UPS-ManagementSoftware can be adjusted to your demands.

The UPS management software includes with every serial number the licence for using theUPS service on one server with one UPS and an unlimited numbers of connected WINDOWSworkstations. When operating with two or more servers a licence for every additional server isrequired. It doesn’t matter if the UPS service runs at that location or if the server is halted by aUPS service via remote command. The same regulations are applicable to the use of remotesend/receive modules RCCMD and multiserver shutdown under NT, UNIX and other operatingsystems. The service programs are generally delivered as a single-licence. To use a singleCD ROM to shutdown multiple servers you have to purchase additional CD license keys.

Parallel/redundant UPS systems are also manageable by the software.

The main principle is: let introduce a shutdown of a Server only when strictly necessary. Acorrect Parallel Handling has therefore to manage a parallel system as a whole and alwaysconsidering redundancy. Following statements apply:

- Every alarm on any unit is immediately notified, but …

- … a reaction to a severe fault is introduced only when the minimum number of UPS –Modules necessary to supply the load exhibits an alarming situation.

- The real Battery autonomy time of the (whole) parallel system is computed continuously.

- Maintenance on a redundant unit may be executed without annoyance to the managementsystem (supervisor).

In order to be managed, a RITTAL UPS can be integrated into a network in two ways:

1. By means of the server which is being powered by the UPS and is integrated in thenetwork. In most of the cases the server is used as sub-agent and you only need the PMC-Software without any SNMP Adapter. You need a standard serial connection between theRS232 SMART port of the UPS and the RS232 port of the computer/server.

2. In some situations it is preferable to interface the network via an SNMP adapter. By this wayup to 50 computers can be shut down in a RCCMD environment. RCCMD (Remote ConsoleCommand) is an additional software module, which can be triggered by the SNMP device toexecutes a command (typically a shutdown command) on a remote system.

A3346302IT74-GB 55

9.6 SNMP CARD/ADAPTER FOR NETWORK MANAGEMENT /REMOTE MONITORING

The Simple Network Management Protocol (SNMP) is a worldwide-standardizedcommunication-protocol. It is used to monitor any device in the network via simple controllanguage. The UPS-Management Software also provides its data in this SNMP format with itsinternal software agent. The operating system you are using must support the SNMP protocol.We offer our software with SNMP functionality for Novell, OS/2, all Windows running onINTEL and ALPHA, DEC VMS, Apple.

Two types of SNMP interfaces with identical functionality are available: an external SNMP-Adapter (Box) and an internal SNMP-Card. Both can manage a parallel system (N modules)and return either global values - which are consistent for the whole parallel system - or specificvalues from the single modules.

Figure 9.6 SNMP Adapter

The adapter may be configured via Telnet, HTTP (Web-Browser) or serial connection(Terminal). For normal operation at least one network connection (Ethernet) is required.

The SNMP adapter can be used, utilising the RCCMD send function, for an automatic networkwide shut down or just for informing connected users. The shut down procedure can beinitiated on a low residual battery autonomy time (downtime) or by a countdown timer which isstarted at the beginning of the alarm. A shut down is therefore possible without extra inputfrom the operator, and is fully software controlled.

The small (125x70 mm) External SNMP adapter comes with following interfaces:

1. RJ-45 connector for 10/100 Base-T(autoswitchable)2. Serial Port for configuration (COM2) or optional ModBus

interface.3. Error/Link LED for UPS status4. Aux Port5. DIP Switch6. Serial Port to the UPS (COM1)7. DC Supply (9 VDC or 9-36 VDC supply, depending on model);

Figure 9.7 External SNMP Adapter

The Internal SNMP-Card can be inserted into an appropriateextension slot of the PMC. This adapter communicates via the serialport of the UPS and makes a direct multiple server shut downpossible without additional SNMP management software.

Figure 9.8 Internal SNMP Adapter

For detailed information please see Software Manual provided with the PMC-Software CDROM.RCCMD - Remote Console Command module for a multi-server shutdown. Thisstand-alone software module is designed to receive and execute a command issued by aremote device. Thanks to RCCMD it is possible to execute a shutdown in an heterogeneousmultiplatform network. The new release RCCMD2 is an application available for all OperatingSystems, analogous to PMC-Software. Our SNMP Interfaces are compatible to RCCMD.
