Level the Power Module
Once the power module is on the site, the landing gear on the trailer should be lowered in order to support the trailer. The truck should be removed from the trailer. Install the jack stands underneath the front of the trailer.
Before you operate the power module, level the power module. This will prevent a low coolant level alarm from sounding. This will also prevent the makeup oil supply (if equipped) from overfilling the engine crankcase.

(1) Adjustment for the landing gear | |
Use a level in order to verify if the power module is level front to the rear. Position the level on the side of the power module. Adjust the landing gear upward or adjust the landing gear downward in order to make the adjustment. The power module should be level within a 1/4 of a bubble on the level from the front to the rear.

(1) Adjustment for a jack stand | |
Use a level in order to verify if the power module is level from one side to the other side. Position the level on the front of the power module. Turn the jack stands upward or turn the jack stands downward in order to make the adjustment. The power module should be within 1/4 of a bubble on the level from one side to the other side. The radiator filler cap must be on the high side of level if the power module can not be completely level.
Multiple Units

Many electric power generation applications require several power modules to be operated. When you select a site, recommended spacing should be observed. There should be a minimum spacing of 6 m (20 ft) for less than five power modules that are placed beside each other. There should be a minimum spacing of 8 m (25 ft) for more than five power modules that are placed beside each other. This space between the power modules will allow fresh air to enter the air inlet openings. The power modules should be oriented so the radiator cooling air flow and engine exhaust will flow with the prevailing wind direction in order to prevent engine exhaust from recirculating into the power module.

The outlet of the cooling fan should be positioned in opposite directions if the power modules are placed behind each other. The radiator cooling air flow and engine exhaust from one power module should be directed away from the air inlet of another power module. To prevent recirculation of cooling air and exhaust, the minimum spacing between power modules is 15 m (50 ft).
Power Module Ground
 |
The Power Module must be properly grounded to prevent accidental injury or death from electrocution. |
 |
The switchgear in the power module controls the connection of the generator set to the electric system. The generator frame is grounded to the frame of the floor-standing switchgear. The switchgear must be connected to an earth ground at the site while the power module is operated. This consists of a ground cable from the ground bar at the switchgear to a ground stake. Consult local wiring codes in order to find the correct cable size and stake material for the appropriate electric load.
When several generators are operating in parallel, connecting all neutral bus bars can result in current circulating through the neutral connections. See this Operation and Maintenance Manual, "Generator Lead Connections" for further information.
Ladders
The power module is equipped with ladders for easier access into the doors. The ladders should be installed once the power module is parked.

The ladders for the power module are stored inside the storage boxes. Install the ladders on each door. The ladders are attached at the bottom of each door opening.
There may also be hooks for the ladders on both sides of the power module for the access doors to the air cleaners, and on the rear of the power module in order to access the makeup oil tank.
