Shielding guidelines

9Installation

As a general rule, Reliance Electric recommends shielding

of all conductors if:

• wire lengths exceed 4 inches and power and logic leads

must be bundled together*; or

• radiated and/or conducted noise must be minimized due

to concerns about immunity or general compliance (CE,

FCC, etc.)

* Reliance Electric considers this an unfavorable condition and does

not recommend bundling power and logic leads for any length.

ATTENTION: If it is not practical to shield power

conductors, Reliance Electric recommends shielding all

logic-level leads. If shielding is not practical, use

twisted-pair control wiring to minimize induced noise.

ATTENTION: Under no circumstances should power

and logic leads be bundled together. Induced voltage

can cause unpredictable behavior any electronic device,

including motor controls.
