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 conguration. The following illustrations and directions are for changing that con-

guration 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.
