1. Input POWER ON/OFF Switch
This toggle switch turns the machine on or off.
Putting the switch in the ON “ ” position ener-
gizes the machine’s input contactor applying input
power to the machine. Switching the switch to the
OFF “ ” position de-energizes the input con-
tactor.
2. POWER Light
When the POWER switch is in the ON position the
machine’s white POWER light will illuminate. If the
input contactor de-energizes the machine in an
abnormal situation the pilot light will still illuminate.
In this situation it may be necessary to reset the
machine by switching the POWER switch to the
OFF and then to the ON position. (See Overload,
Overcurrent, and Fault Protection Section)
