Before Installing the CPX2000 Series Chassis

Power Cords
Motorola systems have detachable power cords that you can plug in at both
the wall socket and the equipment. Place the chassis within six feet of the
electric receptacle.
Note Do not use extension cords.
Cables
Your CPX2000 Series system chassis, console and some other peripherals
use shielded cables. You can successfully use shielded cables for
communication over extended distances. Reliable communication over
cables longer than 50 feet, however, depends on the absence of electrical
noise, correct ground potentials at termination points and other variables.
Cable Planning
When planning the installation of cables:
❏
Do not run signal cables parallel to AC power cables if they are
within four inches of each other.
❏
Do not install signal cables close to electric motors, power line
regulators, relays or power supplies.
❏
Avoid laying signal cables close to air conditioners, copy machines,
water coolers and other similar equipment that generates power line
“noise.”
❏
Do not run signal cables near equipment that generates radio
frequency interference (for example, radio transmitters).
❏
Do not expose cables to moisture or heat. If you install signal cables
outdoors, use a conduit or raceway to protect them from lightning
and weather.
❏
Use shielded cable to ensure radio frequency compatibility.
