4.2 Wire Routing
To avoid induced noise (transfer of electrical energy from one wire to another), keep
input wiring isolated from high current output and power-limited wiring. Induced noise
can interfere with telephone communication or even cause false alarms. Avoid pulling
a single multiconductor cable for the entire system. Instead, separate high current
input/output from low current. Separate power-limited from non-power-limited wiring.
Non-power-limited wiring must be enclosed in conduit.
Wiring within the cabinet should be routed around the perimeter of the cabinet. It
should not cross the printed circuit board where it could induce noise into the
sensitive microelectronics or pick up unwanted RF noise from the switching power
supply circuit.

Note: The use of this knock out will reduce the number and/or size
of batteries this cabinet can contain. Evaluation of space is
important before using.
