INSTALLATION
SECTION 1
STANDARD INSTALLATION DETAILS
MOUNTING
CONSIDERATIONS
The common equipment cabinet should be attached
vertically to any sturdy, flat surface. It may be
vertically rack-mounted if desired.
The cabinet must be located within six feet of a
proper electrical outlet. The system requires a
dedicated 117VAC 15 AMP circuit, with a third-wire
ground, supplied to a standard electrical outlet
(NEMA
5-15R).
The distance between the common equipment and
the TELCO/PBX 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-l 22 degrees F
(O-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 common
equipment mounting. Suitable mounting
backboards are available commercially or can be
constructed out of
in-inch
plywood cut to size.
SPECIAL MOUNTING CONSIDERATION
When the battery back-up is to be included as part of
the installation, the optional external batteries, cable
assembly, the common equipment, and the wiring
connections must be located in a dedicated equipment
room (as defined in the National Electric Code
published by The National Fire Protection Association,
Quincy MA, 02269).

MOUNTING PROCEDURE
Unpack and carefully inspect all equipment for
shipping damage. Notify the shipper immediately
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 location,
attach it securely to provide a stable mounting
surface for the equipment.
Refer to
Flgure
3-l
for the locating dimensions
required for the three mounting screws, and mark
their locations on the mounting surface.
Drill 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 dictated by
the type of mounting surface.
Insert the two top screws into the mounting surface
and tighten them to within approximately l/8-inch
of the surface.
Hang the cabinet on the top screws using the
mounting holes located on the rear of the cabinet.
Note that these holes are elongated with an
enlargement at one end. This feature allows the
cabinet to snap down on the screws to secure the
mounting when the cabinet is hung on them.
Insert a third screw through the mounting tab
located on the lower edge of the cabinet and into
the mounting surface, and tighten it into place.
Place the individual telephone stations as desired
and in keeping with accepted industry and off ice
standards. A telephone station can be wall
mounted if necessary as they are desk/wall
reversible. Refer to Chapter 6, Maintenance, for
instructions in preparing a desk/wall reversible
station for wall mounting.
