A. Cover Removal
1. Remove the upper and lower screws
which secure the cover to the main assem-
bly. 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.

B. Cover Installation
1. Reverse previous procedures for cover
installation.
NOTE
When installing the upper screws, attempt to
reuse the original threads. The easaiest way to
do this is by turning the screw counter-clockwise
until you feel the threads lign 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.
