The unit should have adequate clearance on all sides to allow proper air flow. Allow approximately 2 m (6.6 ft) of clearance on all sides.

• Place the unit in a stable position.

• Ensure that you use wheel chocks that are suitable for the trailer.

• Unfasten the tow vehicle before you operate the unit.

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.

Note: The procedure for the load connection is illustrated by using a dual voltage distribution panel. All instructions are typical for both the dual voltage distribution panel and for the single voltage distribution panel.

1. Ensure that the generator set is not operating. Place main circuit breakers 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 or bus bars.

2. Connect the output power cables to the receptacles or to the bus bars.

   If necessary, connect the output power cables to the bus bars:

   1. Connect the output power cables to the appropriate bus bars .

   Failure to connect the unit to a suitable grounding electrode can result in electrical shock and may cause injury or death.

3. Connect the ground connection to a suitable grounding electrode of no more than 25 ohms.

4. Connect the control wiring (if equipped) for the automatic start/stop to the connection points for the remote start/stop.

5. Close circuit breakers after the connection is made and the engine is running.
