Enclosure Door Cutout
The 2800 is designed to be mounted in the
door of an enclosure or on an operators
console. Care must be taken to prevent
metal chips or other conductive particles
such as wire clippings from entering the unit.
Failure to protect the unit may cause damage
when power is applied and may void the
warranty.
A minimum clearance of six inches should be
kept between the 2800 and any other device
that generates heat. In the event that the
internal enclosure temperature periodically
exceeds 50
E
C (122
E
F), fans or a purge air
system must be used.

Wiring Considerations
Care should be taken when routing DC power supply wires and the communication cable. Follow these guidelines
for a trouble free installation. The DC power lines and communication cable must be kept away from AC power
lines. Keep both at least one foot away from 115 VAC lines, and two feet away from higher voltage lines. This
especially applies to the communication cable. If the cables must cross AC power lines, cross them at right angles
(90
E
). Keep the cables away from sources of high energy fields such as arc welders, AC motors, motor starters,
servo controllers, generators, induction heaters, and transformers.
