Figure 13.  Connecting Loads

Connecting Loads

Loads can be connected to the generator by the 

Ouput

Terminal Lugs

 or the convienience receptacles (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, 175A 

main 

circuit breaker is provided. Make sure to

switch 

ALL

 circuit breakers to the 

OFF

 position prior to

starting the engine.

DCA-70SSIU (60 Hz)  — OUTPUT  TERMINAL PANEL FAMILIARIZATION

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.

Figure 14. Over Current Relay

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).

Figure 15.  Blower Fan Fuse

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.
