ELECTRONICS GP 4388494 - Caterpillar

The XQ175 distribution panel is equipped with a single adjustable main circuit breaker that is adjustable for 208 volts or 480 volts. The panel is equipped with a manual voltage changeover board and a single main load connection.Manually Change the Voltage for the Dual Voltage Distribution Panel with the Voltage Changeover Board on XQ175 Generator Sets
DANGER: Shock/Electrocution Hazard-Do not operate this equipment or work on this equipment unless you have read and understand the instructions and warnings in the Operation and Maintenance Manual. Failure to follow the instructions or heed the warnings will result in serious injury or death.
Ensure that the generator set is not operating. Place the handle of the main circuit breaker in the "OFF" position. The "OFF" position is the open position.

DANGER: Shock/Electrocution Hazard-Do not operate this equipment or work on this equipment unless you have read and understand the instructions and warnings in the Operation and Maintenance Manual. Failure to follow the instructions or heed the warnings will result in serious injury or death.
Verify the correct load phase rotation with the generator prior to connecting the output power cables.
Note: The procedure for the load connection is illustrated by using a XQ175 dual voltage distribution panel. All of the instructions are typical for both the dual voltage distribution panel and for the single voltage distribution panel.

Ensure that the generator set is not operating. Place main circuit breakers (1) in the "OFF" position. The "OFF" position is the open position.Dual voltage distribution panels can have two different voltages. Determine the voltage to use. Use either HIGH (480 V) or LOW (208 V) voltage. Select the applicable receptacles (5) or bus bars (3) .
Connect the output power cables to the receptacles (5) or to the bus bars (3) .If it is necessary to connect the output power cables to the bus bars:
Connect the output power cables to the appropriate bus bars (3) .
Failure to connect the unit to a suitable grounding electrode can result in electrical shock and may cause injury or death.
