DCA-125USJ — GENERATOR START-UP PROCEDURE (MANUAL)

Before Starting

CAUTION - LETHAL EXHAUST HAZARD

The engine's exhaust contains harmful emissions.

ALWAYS have adequate ventilation when operating.

Direct exhaust away from nearby personnel.

WARNING - STARTINGTHE GENERATOR

NEVER! manually start the engine with the main, GFCI or auxiliary circuit breakers in the ON (closed) position.

1.Place the main,G.F.C.I. and aux. circuit breakers (Figure 39) in the OFF position prior to starting the engine.

5.Place the voltage selector switch in the desired voltage position (Figure 41).

Circuit Breakers (OFF)

2.Connect the load to the receptacles or the Output Terminal Lugs as shown in Figure 13. These load connection points can be found on the output terminal panel and the output terminal panel’s hard wire hookup panel.

3.The output terminal lugs are protected by a plastic cover. Remove this cover to gain access to the terminals. Tighten terminal nuts securely to prevent load wires from slipping out.

4.Close all engine enclosure doors (Figure 40).

(Manual Position)

In cold weather conditions, placing the MPEC Control Switch in the MANUAL position will preheat and start the engine AUTOMATICALLY. The Preheat Lamp (Figure 43) will turn off when the engine has started.

7.Once the engine starts, let the engine run for 1-2 minutes. Listen for any abnormal noises.
