OPERATING INSTRUCTIONS
Section I. OPERATING PROCEDURES
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.
a.
Generator Set Operating Procedures.
WARNING
Do not operate power unit generator set until properly grounded (paragraph 4-
2, b.). Serious injury or death by electrocution can result from operating an
ungrounded generator set.
Operating noise level of generator set can cause hearing damage . Ear
protectors, as recommended by medical or safety officer, must be worn when
working near power unit.
Make sure ICC or CRG generator power switch is in OFF position before
starting or stopping generator set.
CAUTION
To avoid damage to equipment, make certain of voltage, frequency, and phase
requirements of load connected to power unit.
NOTE
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 operating instructions on the data plate. To switch the power source from the primary
power unit to the standby unit, shut down the primary unit as outlined on the instruction plate and repeat startup
and operating procedures using standby unit. For paralleling instructions, refer to TM 5-6115-465-12.
