Removal Procedure
- Place the system in bypass mode by turning the keyswitch to the Bypass position.
- Isolate the system from the load by closing the bypass circuit breakers.
- Open the circuit breaker for the output of the system.
- Open the AC circuit breaker for the input of the system.
- Allow the capacitor banks to bleed down for approximately 5 minutes.
Note: When the flywheel is spinning, the following components are energized: the bus, the armature leads and the fuses. Accomplish the procedure as quickly as possible. During the procedure, the rotor is spinning on the bottom bearing.
- Label all of the input wires and all of the output wires.
- Disconnect the input connector from terminal "J4".
- Disconnect the "APC I/O" connector from terminal "J10".
- Disconnect the "Contact Status" connector from terminal "J8".
- Disconnect the "CR Out" connector from terminal "J9".
- Disconnect the "110 In" connector from terminal "J7".
- Disconnect the "Contactor Control" connector from terminal "J3".
- Disconnect the "CT I/O" connector from terminal "J2".
- Disconnect the "Input Voltage" connector from terminal "J1".
- Disconnect the "Inverter Voltage" connector from terminal "J11".
- Disconnect the "Output Voltage" connector from terminal "J12".
- Remove the board from the ten plastic mounting spacers.
Installation Procedure
- Install the board.
- Connect the "Output Voltage" connector to terminal "J12".
- Connect the "Inverter Voltage" connector to terminal "J11".
- Connect the "Input Voltage" connector to terminal "J1".
- Connect the "CT I/O" connector to terminal "J2".
- Connect the "Contactor Control" connector to terminal "J3".
- Connect the "110 In" connector to terminal "J7".
- Connect the "CR Out" connector to terminal "J9".
- Connect the "Contact Status" connector to terminal "J8".
- Connect the "APC I/O" connector to terminal "J10".
- Connect the input connector to terminal "J4".
- Calibrate the AC Voltage and the AC Current. Proceed to Testing and Adjusting, "AC Voltage".
