CARTRIDGE ASSEM. 4N4040 - Caterpillar

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 earth ground consists of a ground strap 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.Handling
Improper handling of the equipment may result in personal injury or death or damage to the equipment. Handle with care and move the equipment slowly. Ensure that the equipment is not handled in a rough manner. Bodily contact with electrical potential will cause personal injury or death.
After the power module has been inspected, determine whether the shipment is complete. Determine whether the shipment is correct.
Handle the power module with care. Rough handling may damage internal components and to external components.
Avoid scratching or marring of the finish of the power module container. Imperfections in the finish will allow rusting to begin.
When you ship the power module, the generator circuit breaker must be in the CONNECTED position. Exhaust Stack
This unit has an exhaust stack that may be stored inside the enclosure when the unit is being shipped. The exhaust stack must be assembled as described in the following procedure, prior to using the unit.Note: To prevent rain water from entering the engine, the exhaust must be covered with a rain cap or similar when the generator set is not running. The exhaust hole in the container must be covered if the exhaust stack is removed. If the hole is left uncovered, water could damage the engine.
