SECTION 200-096-205
FEBRUARY 1991
1 GENERAL
1 .OO This chapter provides the procedures neces-
sary to install the DK KSUs. The chapter includes
mounting considerations, grounding instructions,
and instructions to test the power supply. Instruc-
tions to remove and replace the power supply are
also provided.
2 KSU INSTALLATION
2.00 The KSU may be either wall-mounted or
table-top mounted. The following paragraphs
provide procedures for both mounting options.
2.01 To optimize airflow and ventilation:
l
Ensure that the installation site provides the
minimum clearances specified in Installation
Site Requirements, Section 200-096-203,
Paragraph 3.
l
Do not block the ventilation holes at the rear
and both sides of the KSU.
2.10 Wall Mounting
1) Install the three wall-mounting brackets (packed
in the shipping carton with the KSU) on the rear
of the KSU in both upper corners, and at the
bottom center. Secure each bracket to the KSU
with the back panel screws and the screws
supplied with the brackets (see Figure 5-l).
NOTE:
The KSU back panel should not be removed.
2) Mark the appropriate mounting screw locations
on the wall by using Figure 5-1, or hold the KSU
against the wall at the selected mounting lo-
cation. Mark the positions of the holes in the flat
part of each mounting bracket where they
contact the wall. Mounting screws will be in-
stalled at these locations.
NOTE:
Wall anchors are required for dry-wall sur-
faces where studs do not align with the
I
mounting screw locations (see Figure 5-6).
1 3)
Install two 1.25-inch long panhead wood screws
approximately half way into the wall at the
upper mounting bracket locations.

WALL MOUNTING BRACKET INSTALLATION
4) Hang the KSU from the top two mounting
screws.
5) Install a third 1.25-inch panhead wood screw I
through the hole in the bottom mounting bracket.
6) Tighten the three mounting screws firmly to
secure the KSU to the wall.
2.20 Table-top Mounting
2.21
Table-top mounting requires no special in-
stallation procedures. However, it is suggested
that the top wall-mounting brackets be installed to
ensure adequate ventilation at all times.
NOTE:
Do not install the KSU directly on the floor.
2.30 KSU AC Power and Ground
2.31
Ensure the system AC power and earth
ground complies with the requirements listed in
Installation Site Requirements, Section 200-096-
203, prior to connecting the AC power plug.
NOTE:
TheACpowermustbe dedicated to the KSU.
Do not use power/ground intended for an-
other piece of equipment.
2.32 Ensure that
SG/FG
and
LG/FG
ground straps
are installed.
