Site Planning - Comdial DX-80 Technical Manual

Installing the DX-80

2.2 Site Planning

The first step in site planning is establishing suitable environmental conditions for the system.
1. 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.
This must be an isolated, dedicated AC circuit for proper operation.
Run all three wires (power, neutral, and ground) 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 dis-
tance between the KSU and the outlet. Do not use an extension cord.
Note: To protect the system from lightning damage or other AC power line disturbances, install
a surge protector.
2. Select the KSU location to minimize cable run length. Terminal equipment connected to the
system must not exceed specified limits (see Section 1.15, Specifications).
3. 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).
The DX-80 system must be installed in a climate controlled environ-
ment. This equipment cannot function in environments above 95
4. 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.
5. For cooling purposes, ample air space (at least four inches on the top, bottom, left and right
sides) must be provided for the KSU.
6. SMDR/SMDA output devices 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 Section 1.15.4, Environmental Data.
