1 Introduction Eltek Energy is a world leader in the development of new power supply systems, designed to meet the rapid growth within the field of telecommunication, as well as the increasingly stringent reliability requirements. With the introduction of microelectronics in electronic equipment, energy distribution and telecommunication and data systems technology require a guaranteed, uninterruptible power supply and to meet this demand, Eltek Energy make in-depth investments in all types of scientific research, technical development, and experimental mathematical modeling of thermal characteristics of components and systems. The ultimate in reliability is secured through innovative new technologies and topologies, which reduces the size of the power blocks and extend the operating range, thereby increasing efficiency and reducing costs. Eltek Energy invests heavily in research and development - with highly qualified engineers and research scientists working with the most advanced development platforms available, we are able to offer tailor-made solutions - a key factor for penetrating new markets. A modern power supply system must fulfill various international standards and regulations while, at the same time, meeting market requirements. Increased awareness of Electromagnetic Compatibility (EMC), especially in Europe, has resulted in Eltek’s investment in an EMC test laboratory. This laboratory not only ensures that products comply with relevant standards, it is also utilized throughout product development. The EMC test laboratory forms part of Eltek’s extensive in-house test facility. Electronic equipment for data and telecommunications require supply voltages generated from the AC mains, as well as from battery-assisted DC voltage. Intensive development work has produced power supply systems designed to meet both present and future power requirements, and the development of control and alarm modules make our power supply systems a market leader. Programmed functions monitor operating conditions, load and battery. Should problems be detected, the operator will be notified immediately, either via the telephone network, or via Ethernet. Shutdowns can thus be avoided for critical applications. Eltek’s software expertise is constantly expanding the remote communication capabilities of our systems, using standard network protocols such as SNMP and HTTP. Eltek Energy AS accepts no responsibility for any damage or injury to the system, site or personnel caused by drawings, instructions or procedures not prepared by Eltek Energy.

2 General Information This manual provides detailed instructions for installing the Flatpack® FP1UD AM, 1U 125A power system. Flatpack Power Systems are made up of Power Shelves for plug-in rectifier modules, a DC distribution that includes a monitoring and control unit and optional batteries. The power shelves include the necessary amount of rectifiers needed in the system. The DC distribution may include fuses, circuit breakers, and load and/or battery disconnect contactors, as well as a Monitoring & Control Unit. This document contains information about the Flatpack FP1UD AM-125A DC system. It includes information about alarm connections, DC connections and optional equipment, together with a description on how to install the distribution. Flatpack FP1UD AM-125A is a 1U high, front access, DC distribution unit designed for mounting into 19” rack cabinets. All load and battery connections are available at the rear of the unit. Alarm output connections are located on the rear of the unit, on the far right side as viewed from the rear, behind the monitoring unit. Box-clamp terminals are provided for the AC mains input connections, in a compartment in the left rear corner (rear view) of the rectifier power rack. An optional removable rear cover prevents accidental contact with the mains wiring after installation. The system can be mounted into customer equipment racks or it can be supplied in Eltek’s own racks. The unit can be flush-mounted or mid-mounted. Extenders are available for installation into ETSI standard or 23” racks. The FP1UD AM-125A DC System contains the LVD contactors and all interconnecting bus work, and the Flatpack Monitor and Control Unit (MCU). All DC electrical interconnections are bolted copper bus bar connections for maximum reliability and minimum voltage drop.

General Information


2.1 Dimensions and Weight Total system height at maximum build-out with Flatpack® rectifiers. A maximum of two power racks can be supplied. This system is then 3U (5.25” or 133.3mm) tall. The system is designed for flush or NEBS (mid) mounting in 19”and 23” EIA, or 21” (ETSI) equipment racks. Overall system depth is 11.6” (295mm). Mid mounting: horizontal protrusion is 5 inches (127mm) from the front of the equipment rack rail and 6.5 inches (165mm) behind the front rack mounting surface. The fully equipped (1 LVD contactor) 1U distribution system (core section) alone weighs approximately 12.3 lbs (5.6 kg). Models with no LVD contactors weigh slightly less.

2.2 Total DC Current The Flatpack® 1U Distribution supports up to four Flatpack® rectifiers for up to 120 amperes of total charge current. Shunt and conductor ratings allow a maximum of 125A battery discharge (load) current.

2.3 List of Tools Required Caution: Use of fully insulated tools is required when working with any powered AC or DC circuits. Never work alone. If insulated tools are not available, do not apply AC power or make any battery connections.

The following tools are required for the installation: Standard wrench and/or socket set (1/4” to 1”) Torque wrench (see Table 3 for required range) Small flat blade screwdriver or awl (3/32” maximum width) Standard and Phillips tip screwdrivers Wire cutters / strippers Hoist with lifting straps (optional)

1503287, Rev1, May 2004 7(18)

2.4 Unpacking the System Rectifiers are shipped separately in their own cartons. Depending on ordering options, the MCU system controller may also be packed separately, or it may be pre-installed in the 1U distribution panel. The assembled system should be lifted by two persons in order to maintain control over the assembly while moving and/or mounting in the host cabinet. After unpacking the system, inspect the assembly for damaged or missing components. Report any problems to Eltek Energy’s Customer Care department. Once the system has been unpacked and inspected, then secure the system into the final mounting location in the host cabinet prior to making electrical connections.

2.5 Mechanical Mounting The system is designed to mount in an EIA standard equipment cabinet having 1.75” rack unit spacing and EIA standard mounting hole spacing. Typically, #12 SAE hardware is used to retain the system assembly within the host cabinet; in some cases #10 SAE hardware may also be used. Under no circumstances should hardware smaller than #10 SAE be used to mount the system into the cabinet rack rails. Use of paint penetrating rack mounting screws is recommended to ensure adequate ground bonding between system components. At least two such screws should be used at each component mounting position (one in each side bracket).

Caution: All mounting bracket hole locations must be populated in order to ensure structural integrity of the system within the host cabinet.

2.6 Environmental Information The system is designed to operate in the following environment: • Operating ambient temperature: -40 to +65 degrees C (MCU controller / LCD display –10 to +55 degrees C). • Storage ambient temperature: -40 to +85 degrees C. • Relative Humidity: 0-95%, non-condensing • Elevation: -200 to 5000 feet (-61 to 1524 meters). Between 5000 feet (1524 m) and 13000 feet (3962 m), the ambient temperature is derated by 2°C (3.6°F) per 1000 feet (302 m) as the altitude increases.

3 AC Connections The electrical installation will be detailed in sections. The AC input wiring will be detailed first, followed by the DC wiring.

3.1 AC Service Wiring Options AC input power is connected to the rear of the rectifier racks. Wiring entry points are sized for ½” (trade size) conduit, EMT, or protective bushings / grommets. AC connections are made directly to the AC mains input terminal blocks on the rectifier power racks. AC wiring access and entry is from the rear of the assembly. An entry point for EMT (conduit) is provided at the side of the assembly. Depending on installer preference and installation requirements, wiring may be either routed through the entry hole provided, or individual AC line cords may be connected directly to the AC input terminals and anchored to a (customer-supplied) wire management and support system.

3.1.1 AC Input Current and Wiring Ratings The Flatpack 700 rectifier is a constant power device, operating over an input range of 85 to 300VAC. From 85 to 99V input, output power is limited to 600 watts. From 99V to 312V input, output power is limited to 700 watts. Each power rack accepts up to two (2) rectifiers. The Flatpack 1500 rectifier is a constant power device, operating over an input range of 85 to 275VAC. From 85 to 150V input, output power is limited to 600 watts. From 150V to 185V input, output power is limited to 1130 watts. From 185V to 275V input, output power is limited to 1500 watts. Each power rack accepts up to two (2) rectifiers. Maximum low-line input current per rectifier is approximately 9 amperes for the Flatpack 1500 and 7.5 amp for the Flatpack 700. For the Flatpack 1500 a 20 ampere service feeder / circuit breaker does not provide sufficient margin, and cannot be used to feed two (2) rectifiers at some line voltages. The next higher standard service feeder rating is 30 amperes. It is acceptable to utilize a 25 ampere circuit if local codes permit this configuration, otherwise a 30 ampere rated circuit must be used in the indicated configurations. For the Flatpack 700 a 20 ampere service feeder / circuit breaker can be used to provide power to one power rack (two rectifiers). All wiring calculations are based on the 1999 National Electric Code, tables 310-16 and C4. The wire selection is based on the use of copper wire with 90°C rated insulation installed in a design ambient temperature of 65°C. Use of wire sizes other than factory recommendations must take into consideration the wire insulation ratings, maximum ambient temperature, and type of wire enclosure. Eltek Energy is not responsible for any hazards resulting from incorrect wire size determinations. Contact the factory if assistance is required in determining alternative wire sizing.

AC Connections


3.2 Installing AC Feed Connections Caution: Before proceeding, verify that all AC circuit breakers feeding the system are in the OFF position. Never work alone.

3.2.1 AC Input Connection Remove the rear AC wire way cover, if supplied, to gain access to the rectifier power rack input terminals. See Figure 1. A #2 Philips screwdriver is required to remove the screws retaining the cover. Do not remove the DC bus bar cover.

3.2.1.1 One Feed per Rectifier In this arrangement, each power rack requires two separate AC feeds, and a maximum of six (6) each, 15-ampere 120 VAC or 208/220/240 VAC single-phase service feeds are required. #14 AWG wire is recommended and up to #10 AWG may be used. See Figure 3 for connector arrangement and Figure 4 for termination procedure. The optional shorting jumpers shown in Figure 3 are not installed in this configuration.

3.2.1.2 One Feed per Power Rack (two rectifiers per feed) In this arrangement, each power rack requires a single AC feed, and a maximum of three (3) each, 30-ampere 120 or 208/220/240 VAC single-phase service feeds are required. #12 AWG wire is recommended and up to #10 AWG may be used. See Figure 3 for connector arrangement and Figure 4 for procedure. Note that the red jumpers connect the two rectifiers’ individual feeds together for a single AC power feed per rectifier power rack. These jumpers are shipped attached to the rectifier power racks for on-site installation. Remove the jumpers from their packaging and install as shown in Figure 3.
