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 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.

Twist lock dual voltage 120/240 vac receptacles
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
single-phase 240/120 application
Figure 8. 240/139V 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.
