!
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 be-
fore plugging in or connecting the unit.
The primary power source, fuse, and
any extension cords used must conform
to local electrical code and the recom-
mended circuit protection and wiring
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 configuration. The following illustrations
and directions are for changing that configuration 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 installa-
tion.
NOTE!
When installing the upper screws, at-
tempt 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.
