Site Preparation
General Site Considerations
The first step is to locate an acceptable site for the common equipment
(KSUs, boards, etc.). When locating a mounting site for the KSUs, the
following points must be considered.
The KSUs are designed for wall mounting and should not be
mounted directly to a masonry or plasterboard wall. It is
recommended that a 1/2 inch plywood back board be firmly
mounted to the wall, and the KSU and MDF, if other than the MDF, be
mounted to the back board.
The location must have access to a dedicated 110 Volt AC (±10%), 60
Hz, single-phase circuit with a circuit breaker or fuse rated at 15 amps.
A 3-wire (parallel blade grounded outlet should be within
approximately 6 feet of the lower left rear of the BKSU mounting.
The location must have access to a good earth ground, such as a
metallic cold water pipe with no non-metallic joints. The ground
source should be located as close as possible to the system.
The system should be located in an area which is well ventilated with
a recommended temperature range of 68°-78° F and a relative
humidity range of 5-60% (non condensing).
The system should be located within 25 feet of the telephone
company' s termination point. Also, the location should be within the
prescribed station loop lengths for all keysets and terminals. If
existing cabling is to be used, the location of existing cabling and
conduits should be considered.
Protection from flooding, flammable materials, excessive dust and
vibration.
The site should be away from radio transmitting equipment, arc-
welding devices, copying machines and other electrical equipment
that are capable of generating electrical interferences. Operation of
this equipment in a residential area is likely to cause interference in
which case the user, at their own expense, are required to take
whatever measures may be required to correct the interference.
