Figure 8 DC Terminal Connections Refer to your UPS installation documentation for termination of the DC power cables within the UPS. The DC power cables must be sized so that the maximum voltage drop (due to cable resistance) between the UPS and the flywheel is 2 volts at rated power. CB1 is rated at 250A 500V DC. WARNING Identify and verify polarity (plus (+) and minus (-)) prior to making electrical connections (positive to positive and negative to negative). Improper connections may result in failure or equipment damage. The field-supplied DC power cabling provided by the electrical contractor must be rated 600V and in accordance with local, regional and national electrical codes. Connect the DC power cables according to the table in the Interconnect Diagram. GE Flywheel, Standard and Enhanced, Installation Manual 22

4.5. Grounding The flywheel must be effectively connected to the UPS ground terminal. The ground connection must be as short as possible. The DC power ground lug can accommodate one (1) 13 mm 2 to 125 mm 2 (see Figure 9). Figure 9 Ground Terminal Connections Wire sizes and installation must comply with applicable local, regional and national electrical codes. Connect the ground wires according to the table in the Interconnect Diagram. GE Flywheel, Standard and Enhanced, Installation Manual 23

4.6. Route 4 Auxiliary Control Power Terminal Connections The AC power wires are terminated at TB1 inside the flywheel (see Figure 10). TB1 can accommodate one (1) 2 mm 2 to one (1) 5 mm 2 cable per terminal. Figure 10 Auxiliary Power Terminal Connections The AC power can be 200-240 VAC, single-phase, 50 or 60 Hz AC that must come from the critical bus of a UPS system. The required AC value has been identified prior to shipment so the proper internal settings have been made by the factory. The product nameplate identifies the factory setting. (See Figure 11) Table 4 Auxiliary Control Voltage and Appropriate Circuit Breaker Ratings Auxiliary Input Voltage, Volts AC 200 240 Current, Amps 6 5 Circuit Breaker 15 15 NOTE The AC power is a factory-set feature. If the available power is different from the voltage marked on the nameplate, call your GE Service Representative. The field-supplied AC power wiring provided by the electrical contractor must be in accordance with local, regional and national electrical codes. Connect the AC power cables according to the table in Interconnect Diagram. Figure 11 Enhanced Flywheel Nameplate (sample) GE Flywheel, Standard and Enhanced, Installation Manual 24

4.7. Route 2 and 5 CB1 Controls and Optional Customer Interface Board (CIB) 4.7.1. CB1 Controls (J10) The control wires are terminated at J10 shown in Figure 12. The control wiring allows basic communication between the other equipment and the flywheel. J10 pin 1 is at the top for +24 UVR; pin 2 is for UVR return; pins 3, 4, & 5 are for CB1 Auxiliary contacts, NO, COM and NC respectively. J10 can accommodate one (1) 0.4 mm 2 to 5 mm 2 per terminal. Route control wires as far away from power cables as possible to minimize interference. 4.7.2. Customer Interface Board (CIB) The CIB consists of six relays that allow for remote monitoring of the following signals: Warning (Summary); Shutdown; Alarm (Summary); Ready; Charging; and Discharging. These are potential free Form C contacts; see Technical Reference, CIB for more information.

4.8. Optional Remote Emergency Power Off (REPO) Optional REPO This option is intended to activate an Emergency Power Off (EPO) from a remote location. The EPO interface requires a Normally Open (N.O.) contact. When the contact is closed it invokes an EPO command, the flywheel goes into a shutdown mode and opens the main Circuit Breaker. Figure 13 Remote Emergency Power Off Connections (Optional) Optional REPO Control When this option is purchased, a Normally Open isolated contact must be used. Connections are made to the DIN rail Terminal block shown. GE Flywheel, Standard and Enhanced, Installation Manual 26
