SECTION 1: GENERAL GE Critical Power 129FD Product Manual 1.1 GENERAL The 129FD system is designed to provide up to an output of 800 Amps at 48VDC when fully equipped with sixteen rectifier modules. Two -48 to +24 VDC converter shelves are also available, and when fully loaded with eight converters supply 160 Amps at +24VDC. 48VDC load distribution is 32 positions without converters and 23 when converters are equipped. Converter outputs have 8 positions on the right side. Additional distribution is available (L20, L21, L31, and L32), and all hardware (1/4 on 5/8 ) is provided (lugs must be supplied by the installer.) The 129FD plant is available in 2 basic system configurations. The first are basic rear access systems available in traditional relay rack configurations using GE II s exclusive heavy-duty relay rack, or can be shipped loose (on shipping rails) for mounting in any standard 23 NEMA bay or cabinet. The heavy-duty GE relay rack configurations are ZONE 4 NEBS compliant, with up to 1,100 pounds of batteries in the bottom 2 trays. It is ZONE 2 compliant with up to 4 trays of batteries. The second basic system is a 100% front access version when mounted in the List 120 List 124 frame. This frame allows for mounting next to walls with full replacement or adding of modular rectifier shelves and battery trays. This frame is NEBS ZONE 4 compliant in any configuration. It is recommended to use the optional List 165 battery hold down bracket in ZONE 4 areas for added protection. The plant has been designed to provide various distribution options (up to 600A devices). It includes such features as plug-in circuit breakers, plug-in fuse holders of various types, optional built in converter plant capable of +24V at 160 Amps, and either Low Voltage Battery Disconnect (LVBD) or Low Voltage Load Disconnect (LVLD). All plant interfaces for the system are front accessible when placed in a List 120 List 124 frame. The main source of power for the Power Plant is commercial AC power, which is converted to DC by the modular switchmode rectifiers. Rectifiers are individually AC sourced with an option to supply 2 rectifiers per AC circuit in a diverse method ensuring a low chance of losing 2 critical rectifiers. The system uses a new generation digital controller that focuses on battery health and has hardwire backup. The plant is fully automatic and provides float and recharge capacity. Alarms are given whenever any plant circuit breaker trips, a fuse fails, a rectifier fails, or the plant output voltage goes out of prescribed limits. The plant can interface with a LAN/WAN. The basic controller offers web browser based monitoring and plant setpoints to be accessed and/or changed. Refer to the controller manual (4380400PD) for complete details. Issue 25, May 2015 Page 13

1.2 RECTIFIER The compact SM50H48D rectifier provides 50 Amps at 48VDC (220VAC input) and 25 Amps at 48VDC (110 VAC input). Up to 4 rectifier modules can be equipped in a 23-inch rack-mounted shelf, for a total of 200 Amps per shelf. For rectifier module details, refer to the rectifier product manual (4380421PD) attached at the rear of this manual. Test jacks are located on the bottom left front of each rectifier module to read individual rectifier current. Lift handle to access test jacks 1.2.1 RECTIFIER BLANK PANEL Front View FIGURE 1-1: SM50H48D Rectifier Module Each rectifier shelf may accommodate up to four rectifier modules. All unused rectifier positions must be covered with a rectifier blank panel (GE part number 4361179P). 1.3 RECTIFIER SHELF The rectifier shelf provides 200 Amps at 48VDC when fully equipped with four (4) SM50H48D rectifiers. Four fully loaded shelves may be equipped in the system to provide a total of 800 Amps of 48VDC. 1.4 CONVERTER The SM24P20D converter provides 20 Amps at +24VDC. The high power density, lightweight design, allows up to 4 converter modules to be equipped in a 23-inch rack-mounted shelf, for a total of 80 Amps per shelf. Two fully loaded converter shelves (if equipped) supply a total of 160A. FIGURE 1-2: SM24P20D Converter Module Page 14 Issue 25, May 2015

1.4.1 CONVERTER BLANK PANEL Each converter shelf may accommodate up to four converter modules. All unused converter positions must be covered with a converter blank panel. 1.5 CONVERTER SHELF The converter shelf (if equipped) provides 80 Amps at +24VDC when fully equipped with four (4) SM24P20D converters. Two fully loaded shelves may be equipped in the system to provide a total of 160 Amps of +24VDC. 1.6 DISTRIBUTION Two distribution heads are available for the 129FD system. The first (List 1), for use with NO converter shelves (straight 48V, no +24V) has 32 distribution positions, 16 on the left and 16 on the right in vertical stacks. Each side is rated 500 Amps and the total system is rated 800 Amps. The second distribution head (List 2) is for use with 48V to +24V converters and allows 23 48V distribution positions and 8 +24V distribution positions. The +24V distribution is located at the top of the right side stack. The converter output distribution is NOT designed to be changed in the field. Four supplemental distribution cabinets are available (List 20, List 21, List 31, and List 32) that provide additional distribution points and capabilities. The supplemental cabinets mount above the main distribution cabinet or above another supplemental cabinet. Alarms are sent down via wiring and a connector on the left side of the system. The ground bar in the rear of the supplemental cabinet is connected to the ground bar below by a splice plate to ensure the ground bus rating throughout the entire system is maintained at 800 Amps. The 48V is transferred up the left and right side stacks via small splice plates. The rating in the supplemental cabinets (no mater how many) is 350 Amps (continuous) per side maximum. The left side stack is always 48V. The right side stack is 48V when installed above a List 1 basic, and will be +24V if mounted above a List 2 split bus basic. In the case of List 2 split bus, only a list 20 can be mounted directly on top of the List 2. If List 21, List 31, or List 32 are desired, a list 20 must make the transition from the basic List 2 to the desired supplemental. List 20 provides 20 positions of plug in distribution to increase the number of positions available in the system. When connected, the hot bus splice plates block the top 2 positions on the basic (or List 20 directly below). This gives a net gain of 16 positions. List 21 adds the capability to add 6 (3 per side) large frame (GJ type) single pole circuit breakers. 1 single pole and 1 double pole could be used in each side. It is not recommended that circuits larger than 400 Amps be used due to temperature rise at bus splices. Total continuous load on each side of supplemental cabinets should be kept to 350 Amps or less. Breakers are available with or without shunts for optional monitoring. List 31 adds the capability to add 6 (3 per side) TPL-B (up to 250 Amps) fuse positions. Each position has a shunt for optional monitoring. List 32 adds the capability to add 4 (2 per side) of TPL-C (275A to 400A) fuses. TPL-B (70A to 250A) can also be inserted with an additional adapted cover. Each fuse holder has a shunt for optional monitoring. It is not recommended that larger than 400 Amp circuits be used due to temperature rise at bus splices. 1.7 OPTIONAL LVD (LOW VOLTAGE DISCONNECT) There are two schemes available for LVD, either low voltage load disconnect (LVLD) or low voltage battery disconnect (LVBD). NOTE: Both, L70 and L73, cannot be equipped at the same time. Issue 25, May 2015 Page 15

1.7.1 (INTERNAL) LOW VOLTAGE LOAD DISCONNECT (LVLD) LIST 70 An optional low voltage load disconnect can be built into the load bus and is accomplished by an 800 amp contactor. During an AC outage the output voltage to the plant drops below a predetermined setpoint, the low voltage disconnect will open the loads (both +24V and -48V) from the plant to avoid possible damage to the batteries or equipment. The batteries and rectifiers are on one side of the contactor, and the loads are on the other side. The plant controller monitors the battery voltage to control the contactor. The contactor replaces a bus plate in the charge bus portion of the plant behind the left side distribution module. Wiring for the LVD module is always present in the plant wiring harness and is plugged in when this option is equipped. The system automatically resets and comes back on line to recharge the batteries and supply current to all loads once the AC source is restored. 1.7.2 (INTERNAL) LOW VOLTAGE BATTERY DISCONNECT (LVBD) LIST 73 List 73 is an optional low voltage battery disconnect that is physically the same and located in the same place as the List 70. There is an extra bus that wraps to the rear of the system and covers the normal rectifier connection positions. By terminating the rectifiers on this bus, the charger outputs are moved to the load side of the LVD contactor. All other wiring and cabling remains the same. The system controller/monitor remains powered during all phases of disconnect operation. 1.8 MANUAL BATTERY DISCONNECT 1.8.1 BATTERY DISCONNECT SWITCH Located on the plant digital controller interface is a (guarded) battery disconnect slide switch. If the optional battery disconnect is equipped, this switch will allow the user to manually disconnect the battery bus from the plant. To disconnect the batteries, slide the switch to the right position. To reconnect the batteries, slide the switch to the left position. 1.9 DIGITAL PLANT CONTROLLER The digital plant controller monitors and/or controls voltages, currents, temperatures, and other parameters within the 129FD and displays this data via the LCD screen. The digital plant controller consolidates all data and provides all interface functions for the power system, including both local and remote capabilities for monitoring and providing setpoint information. For complete details, refer to the digital plant controller manual (4380400PD). 1.10 OPTIONAL BATTERY / SHUNT MONITORING MODULE (ADAC) The battery/shunt monitor module (also referred to as the ADAC monitoring module) is an optional factory/field configurable device used to monitor load shunts and/or battery measurements. Using a combination of known module types and the battery/shunt monitor module dipswitches, the end user can configure each monitored point as one of five (5) basic measurement types: Branch shunt current (30 max per system) Battery current (24 strings max per system) Battery temperature (24 strings max per system) Battery midpoint (24 strings max per system) Battery sense (6 max per system) For more information about the optional ADAC module refer to the digital plant controller manual (4380400PD). For ordering information, refer to the J-Drawing attached to the rear of this manual. Page 16 Issue 25, May 2015

SECTION 3: OPERATIONAL CHECKOUT 3.1 GENERAL The following procedure should be followed after installation. After performing any maintenance to the system, follow the procedure detailed in section 3.3. It is assumed that the system is installed in the plant, input power is available, outputs are tied to the applicable loads, and all other system interfaces have been made. NOTE: Alarms will be sent. Notify alarm surveillance personnel. 3.2 INITIAL PHOENIX DIGITAL CONTROLLER START UP ROUTINE 1. Remove F1 (CONTRL fuse) from the plant interconnect card (620668P or 6200668P-1) located within the plant distribution head. F1 is a 3 Amp GMT fuse. 2. Remove all rectifier modules and converter modules from the plant. 3. If equipped, turn each battery string breaker ON (one string at a time). This will apply battery potential to the power plant. 4. Once all battery string disconnect breakers are ON, replace F1 (CONTRL fuse) into the plant interconnect card (6200668P or 6200668P-1), located within the plant distribution head. F1 is a 3 Amp GMT fuse. This will start the digital controller initialization / self-test process. 5. The plant digital controller initialization / self-test will start within 30 seconds. During the start up, the LCD screen will flash SELF TESTS PASSED. Each LED on the front of the digital controller will cycle in order from the top left position to the bottom right position. Refer to Figure 3-1 for a visual representation of what the digital controller LCD screen will display once the plant digital controller self test is complete.

3.3 INITIAL TURN-ON AND SYSTEM OUTPUT VOLTAGE VERIFICATION 1. Install each rectifier module. 2. If equipped, verify that each input breaker (on the front of each converter module) is in the OFF position and install each converter module. 3. Apply AC Power to each rectifier, one at a time. Each rectifier will start up and begin communications with the plant digital controller. Once AC Power has been applied to all of the installed rectifier modules, visually verify that the green LED AC OK and the green LED DC OK are illuminated on each rectifier module. Verify that the RECTIFIER MAJOR (or RECTIFIER MINOR) LED and the AC FAIL LED on the plant digital controller are extinguished. If the system is equipped with converters, the plant digital controller should still be reporting a POWER MAJOR alarm. 4. If equipped, turn "ON" each converter breaker (located on the front of each converter module), one at a time. When all converters in the bay have successfully been powered on, the POWER MAJOR LED on the plant digital controller will extinguish. 5. The plant digital controller OK LED (green) and FLOAT MODE (green) should be the only two LEDs illuminated on the front of the plant digital controller panel. If any alarms are still showing on the plant digital controller, refer to section 6.2. a. Verify that the only front panel LEDs illuminated are SYSOK and FLOAT MODE. b. Verify the controller reports no alarms. c. Verify communications to the rectifier by looking at status of all rectifiers. d. Verify communications to the converters by looking at status of all converters. e. Verify plant voltage displayed on controller is ± 0.05V of voltage measured between +24V bus, and GND bus using an external calibrated meter. f. Verify Plant Voltage is equal to the Float Voltage Setpoint ± 0.05V. NOTE: Before performing the following tests, verify that the plant is operating normal (showing no alarms). The only two LEDs illuminated on the front of the plant digital controller should be the Green SYSOK LED and the Green FLOAT LED. 3.4 DISTRIBUTION FUSE ALARM TEST The following procedure will demonstrate what happens during a distribution fuse failure. A. Simulate a circuit breaker trip by temporarily strapping the two alarm pins (use an empty circuit breaker position, if available) in the distribution head (once for the 48V distribution and once for the +24V distribution, if equipped). The following will occur: 1. The Red PMJ LED and the Red DISTRIBUTION FUSE LED will illuminate on the front of the plant digital controller panel. B. Remove the temporary jumper from the distribution head and the system will react as follows: 1. The Red PMJ LED and the Red DISTRIBUTION FUSE LED will extinguish and the plant will return to normal operation. Page 38 Issue 25, May 2015
