3.05 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 wir-
ing requirements as specified in Section 2.
Most units are shipped from the factory with a
230 Volt input power cable wired to the input
contactor in the single - phase conguration.
The following illustrations and directions are for
changing that conguration to a different voltage
and or to three - phase operation or back again if a
change had already been made.
A. Cover Removal
1. Remove the upper and lower screws which
secure the cover to the main assembly. Do
not loosen the lower screws inside the cut
out slots in the bottom of the cover.
NOTE
The upper screws and lower screws are
not the same. Do not mix them. The upper
screws are for threading into the plastic of
the front and rear panels. DO NOT use the
finer threaded lower screws for this.

2. Carefully pull the Cover up and away from
the unit.
B. Cover Installation
1. Reverse previous procedures for cover
installation.
NOTE
When installing the upper screws, attempt to
reuse the original threads. The easiest way
to do this is by turning the screw counter-
clockwise until you feel the threads line up,
then begin to turn the screw clockwise to
tighten. Do not over tighten.
C. Input Power Selection
Set the Input Voltage Selection Switch at the rear
of the unit based on the primary input voltage it
is connected to. Low is 208/230 VAC and high is
460 VAC.
