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 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 (See Figure 15) in
the center of the receptacle will check the GFCI function.
Both receptacles should be tested at least once a month.
Reference the maintenance section in this manual for
further testing of the GFCI receptacle

Twist Lock Dual Voltage 120/240 VAC Receptacles
There are three 240/139V, 50 amp auxiliary twist-lock
(CS-6369) receptacles (Figure 16) 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

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.
Voltage Regulator
NOTICE
The voltage regulator (VR) allows the user to increase
or decrease the selected voltage.
Turn the voltage regulator control knob (Figure 17) 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.
