OUTPUT TERMINAL PANEL FAMILIARIZATION
120 VAC GFCI Receptacles
There are two 120 VAC, 20 amp GFCI (Duplex Nema 5-20R) receptacles provided on the output terminal panel. These receptacles can be accessed in any voltage selector switch position. Each receptacle is protected by a 20 amp circuit breaker.These breakers are located directly above the GFCI receptacles. Remember the load output (current) of both GFCI receptacles is dependent on the load requirements of the U, V, and W output terminal lugs.
Pressing the reset button resets the GFCI receptacle after being tripped. Pressing the test button (Figure 7) in the center of the receptacle will check the GFCI function. Both receptacles should be tested at least once a month.

Twist Lock Dual Voltage 120/240 VAC Receptacles
There are three 120/240V, 50 amp auxiliary twist-lock (CS- 6369) receptacles (Figure 8) provided on the output terminal panel. These receptacles can only be accessed when the voltage selector switch is placed in the single- phase 240/120 position.
Figure 8. 120/240V Twist-Lock
Auxiliary Receptacles
Each auxiliary receptacle is protected by a 50 amp circuit breaker. These breakers are located directly above the GFCI 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 9) on the control panel to obtain the desired voltage.Turning the knob clockwise will increase the voltage, turning the knob counter-clockwise will decrease the voltage.

Removing the Plastic Face Plate (Hard Wire Hookup Panel)
The output terminal lugs are protected by a plastic face plate cover (Figure 10). Un-screw the securing bolts and lift the plastic terminal cover to gain access to the terminal enclosure.
After the load wires have been securely attached to the terminal lugs, reinstall the plastic face plate.
