OUTPUT TERMINAL PANEL FAMILIARIZATION

Twist Lock Dual Voltage 240/139 VAC Receptacles

There are three 240/139V, 50 amp auxiliary twistlock (CS6369) receptacles (Figure 7) provided on the output terminal panel..

Connecting Loads

Loads can be connected to the generator by the Output Terminal Lugs 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 3pole, 2500A main circuit breaker is provided. Make sure to switch ALL circuit breakers to the OFF position prior to starting the engine.

Figure 7. 240/139V TwistLock Auxiliary

Receptacles

Each auxiliary receptacle is protected by a 50 amp circuit breaker. These breakers are located directly above the auxiliary receptacles. Remember the load output (current) on all three receptacles is dependent on the load requirements of the Output Terminal Lugs.

Turn the voltage regulator control knob (Figure 8) on the control panel to obtain the desired voltage.Turning the knob clockwise will increase the voltage, turning the knob counterclockwise will decrease the voltage.

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.
