Before you start
- Verify that the voltage ratings of the transfer switch, line circuit breakers, and other accessories match the selected line voltage.
- Affix a notice to the generator set after reconnecting to a voltage different from the nameplate voltage.
Procedure
- Place the generator set master switch in the OFF/RESET position.
- Disconnect the engine starting battery, negative (--) lead first. Disconnect power to the battery charger.
- Use the reconnection schematics to determine the voltage configuration. Route leads through current transformers and connect per the diagram.
- If the controller has meters, reposition the meter scale lamp jumper to match the desired voltage.
- Recalibrate the overvoltage shutdown if reconnecting to or from 139/240 V (low wye) or 277/480 V (high wye) 3-phase 4-wire 60 Hz.
- Set the phase selector switch to L1-L2 or connect a voltmeter across leads L1 and L2.
- Reconnect the starting battery, negative (--) lead last. Start the generator set and verify the voltage changed to the desired value; adjust if needed.
- Stop the generator set after completing the voltage adjustment. Replace the controller cover.
