Each voltage selector switch is equipped with a locking mechanism. Once the proper voltage has been selected,
push the red latch on the inside of the switch handle up and insert a padlock through the handle. By locking the handle
in place, you will prevent unauthorized personnel from changing the switch settings.
Note:
UNITS WITHOUT A CONVENIENCE RECEPTACLE BUCK TRANSFORMER AND NOT AT 600V:
When the
voltage selector switch is in position for 277/480V 3Ø, voltage at the two GFCI duplex convenience receptacles is
139 Volts and the voltage at the three twist-lock receptacles is 139/240 volts. When the voltage selector switch is in
position for 120/208V 3Ø, voltage at the two GFCI duplex convenience receptacles is 120 volts and the voltage at
the three twist-lock receptacles is 120/208 volts. When the voltage selector switch is in position for 120/240 3Ø
(DELTA), voltage at the two GFCI duplex convenience receptacles is 120 volts and the
THREE TWIST-LOCK
RECEPTACLES SHOULD NOT BE USED
. When the voltage selector switch is in position for 120/240V 1Ø, voltage
at the two GFCI duplex convenience receptacles is 120 volts and the voltage at the three twist-lock receptacles is
120/240 volts.
