DCA-85USJ — OUTPUT TERMINAL PANEL FAMILIARIZATION

Connecting Loads

Loads can be connected to the generator by the OuputTerminal Lugs or the convienience receptacles. (See Figure 13). Make sure to read the operation manual before attempting to connect a load to the generator.

To protect the output terminals from overload, a 3-pole, 250A main circuit breaker is provided. Make sure to switch ALL circuit breakers to the OFF position prior to starting the engine.

Figure 13. Connecting Loads

Over Current Relay

An over current relay (Figure 14) is connected to the main circuit breaker. In the event of an overload, both the circuit breaker and the over current relay may trip. If the circuit breaker can not be reset, the reset button on the over cur- rent relay must be pressed. The over current relay is lo- cated in the control box.

Blower Fan

This unit has an intake fan located at the rear of the machine to draw outside air into the cabinet to cool the engine. The fan has a 10 amp AC fuse located beneath the Voltage Selector Switch (Figure 15).

DANGER - ELECTROCUTION HAZARDS

This fuse has current running through it any time the engine is running. This fuse is NOT connected to the main circuit breaker of the generator. Attempting to replace the fuse with the engine and/or generator operating

could result in electrocution and severe bodily harm. ALWAYS turn the unit completely off before attempting to replace or handle this fuse.
