2.3 WIRE ROUTING

Notes:
All high voltage and non-power limited wiring must be kept separate from power limited
wiring. A ¼" separation must be maintained, with high voltage and non-power limited
wiring running in separate conduit openings from power wiring.
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. Improper wiring
installation may cause improper operation. Avoid pulling one multi-conductor cable for
the entire system. Instead, separate high current input/output from low current.
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.
