3.03 Primary Input Power Connections
CAUTION
Check your power source for correct voltage before plugging in or connecting the unit. Check the Voltage Selector
at the rear of the unit for correct setting before plugging in or connecting the unit. The primary power source, fuse,
and any extension cords used must conform to local electrical code and the recommended circuit protection and
wiring requirements as specified in Section 2.
Most units are shipped from the factory with a 230Volt input power cable wired to the input contactor in
the single - phase configuration. The following illustrations and directions are for changing that con
-
figuration to a different voltage and or to three - phase operation or back again if a change had already
been made.

Three Phase Input Power Wiring
NOTE
There is only one jumper setting that changes between the single and three phase settings. To change from single
phase to three phase, the jumper connected to L2 needs to be removed and placed on the other L3 connection so both
ends of the jumper are attached to the same electrical point. See previous illustrations.
