2-1. Power Unit Operating Procedures. The typical mission for any mobile power generating
equipment can be described in three steps or phases. In the first phase, the power unit is towed to the worksite
and installed by unit level technicians (paragraph 4-2). In the second phase of the mission, the operator starts the
generator set, runs it to power a system or equipment, and eventually shuts it down. In the final phase, the power
unit is dismantled, packed up and either moved to a new worksite or returned to standby status (paragraph 4-3).
This final phase is also accomplished by unit level technicians.

To avoid damage to equipment, make certain of voltage, frequency, and phase
requirements of load connected to power unit.
Before starting generator set, do your Before PMCS as described in table 3-2.
Detailed procedures for prestarting, starting, operating, and shutting down the power unit generator set are found
in TM 5-6115-465-12 and on the Operating Instruction data plate found on the equipment. Refer to the data plate,
located inside the right hand control panel door to start and run the generator set. Monitor and adjust power
output as required during operation. At the end of the mission, shut down generator set in accordance with the
instructions on the data plate.
