OUTPUT TERMINAL PANEL FAMILIARIZATION
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 change-over 
board configuration. 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 (See Figure 7) in 
the center of the receptacle will check the GFCI function. 
Both receptacles should be tested at least once a month.

There are three 240/139V, 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 change-over board is configured for  
application
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.

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.
