Site Planning

Establishing Suitable Environmental Conditions for the System
•
Place KSU1 (and KSU2 if applicable) within 5 feet (1.5 meters) of an isolated, dedicated, 105-125VAC, 57-63Hz,
15A, single-phase commercial power source.
Note: This must be an isolated, dedicated AC circuit for proper operation. All three wires (power, neutral, and
ground) must be run separately from the outlet to the breaker panel without being bonded to any other wire or
circuit. Do not plug any other equipment into this outlet. To maintain the protection provided by the isolated,
dedicated circuit, the length of the AC power cord limits the distance between the KSU and the outlet. Do not use
an extension cord.
•
To protect the system from lightning damage or other AC power line disturbances, a surge protector should be
installed.
•
Select the KSU location to minimize cable run length. Terminal Equipment connected to the system must not
exceed specified limits (see overview Specifications).
•
The KSU location should not be exposed to direct sunlight, high humidity, heat, dust, or strong magnetic fields
(such as those generated by heavy motors, copy machines and some kitchen appliances).
IMPORTANT! The DX-80 system must be installed in a climate controlled environment. When equipped with
optional voice processing modules, the system takes on the characteristics of a mechanically driven computing
storage device. (A computer with a hard disk drive.)
This equipment cannot function in environments above 95 degrees Fahrenheit ambient temperature.
•
The MDF should consist of a 3/4-inch plywood backboard large enough to mount all hardware and equipment
allowing all components ample space for adequate ventilation and servicing. Allow additional room for external
apparatus, if used.
•
For cooling purposes, ample air space (at least four inches on the top, bottom, left and right sides) should be
provided for the KSU.
•
SMDR/SMDA output device(s) must be placed within 50 feet (15 meters) of the KSU (limited by RS-232C
standard wiring practices).
The equipment should be located in a climate-controlled room adhering to the Environmental
Specifications listed in the Overview section of this manual.
Note: When installing the KSU and station instruments, allow a sufficient margin for error in case of air
conditioning failure, routine maintenance, plant shutdown, etc. As a general rule, if conditions are suitable for
office personnel, they are also suitable for KSU and terminal equipment operation. A properly controlled
environment will help to extend the operating life of the equipment.
From UL 1459, a product safety specification governing telephone equipment:
•
Never install telephone wiring during a lightning storm.
•
Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
•
Never touch non-insulated telephone wires or terminals unless the telephone line has been disconnected at the
network's interface.
•
Use caution when installing or modifying telephone lines.

Tools and Supplies

•
Assemble the correct supplies and tools to install the Comdial DX-80 as it is intended.
•
Use UTP (Unshielded, Twisted-Pair) three or four pair (recommended) cable to run from the MDF (Main
Distribution Frame) to all extension terminals (speakerphones, DSS Consoles and analog devices). Digital
terminals only need one twisted pair to operate. (Additional pairs are always recommended to allow for future
potential uses.)
