CHAPTER 2
INSTALLATION
MOUNTING
CONSIDERATIONS
l
The KSU should be attached vertically to any stur-
dy, flat, surface. It may be vertically rack mounted
if desired.
l
The KSU must be located within six (6) feet of a
proper electrical outlet. The power supply requires
a dedicated
AMP circuit, with a
wire ground, supplied to a standard (NEMA
electrical outlet.
l
The distance between the KSU and the
jacks must be 25 feet or less as per
FCC requirements. A nominal distance of 7 feet is
recommended.
.
The mounting location must be secure and dry and
have adequate ventilation. The temperature range
of the location must be within 32-122 degrees F
50 degrees C), and the relative humidity must be
less than 90 percent non-condensing.
.
If the mounting surface is damp or if it is concrete
or masonry material, a backboard must be attached
to the mounting surface to be used for KSU mount-
ing. Suitable mounting backboards are available
commercially or can be constructed out of
plywood cut to size.
l
Tools and hardware reauired for mountina include:

Fasteners wood screws

round
head), toggle bolts, or wall anchors
Screwdriver -to match fasteners
Electric
if prepared holes are required
Connecting tool for fastening wires to a
66 connector block.
Crimping tool for 623-type modular plugs
MOUNTING PROCEDURE
Unpack, and carefully inspect all equipment for
shipping damage. Notify the shipper im-
mediately of any damages found. Verify that
the packages contain all parts and accessories
needed for proper installation and operation.
If a backboard is required at the mounting loca-
tion, attach it securely to provide a stable
mounting surface for the equipment.

scale mounting template is supplied in the
packing box. Hold
it to the mounting sur-
face, and mark the location of the mounting
holes on the mounting surface as they are lo-
cated on the template. The mounting dimen-
sions are shown on Figure 2-l . .
holes in the mounting surface of a proper
size to accommodate the hardware being used.
If necessary, prepare these holes with inserts,
anchors or other attachment devices as dic-
tated by the type of mounting surface.
Attach the KSU to the mounting surface with
four (4) screws installed through the KSU
mounting flange and into the mounting surface
holes. Note that the flange holes are elongated
with an enlargement at one end. This feature
allows the mounting screws to be partially in-
stalled in the mounting surface before the
cabinets are hung on them.
Place the individual telephone stations as
desired and in keeping with accepted industry
and office standards. Currently produced 8

can be wall mounted if necessary
as they are
reversible. Currently

Refer to Chapter 4, Maintenance, for instructions in
preparing a desk/wall reversible station for wall mount-
ing.
Any previously produced
which may currently
still be in service can also be wall mounted if necessary.
Use a wall mounting bracket (part number 701032-056)
for this purpose.
