OUTPUT TERMINAL PANEL FAMILIARIZATION

Connecting Loads

Loads can be connected to the generator by various 

methods, output terminal lugs, camlocks or the convenience 

receptacles (Figure 9). 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, 

70A 

main

 circuit breaker is provided. Make sure to switch 

ALL

 circuit breakers to the 

OFF

 position prior to starting 

the engine.

Figure 9. Connecting Loads

Over Current Relay

An 

over current relay

 (Figure 10) 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 

current relay must be pressed. The over current relay is 

located in the control box.

Figure 10. Over Current Relay

NOTICE

Remember the

 overcurrent relay

 monitors the current 

flowing from the 

U, N and V Output Terminal Lugs

 to 

the load.
In the event of a short circuit or over current condition, 

it will automatically trip the 70 amp main breaker.
To restore power to the 

Output Terminal Panel

, press 

the reset button on the overcurrent relay and place the 

main

 circuit breaker in the 

closed

 position (

ON

).
