Noise Prevention

 Route field wiring away from any other wiring and as far as possible from

sources of electrical noise, such as motors, transformers, contactors, and AC

devices. As a general rule allow at least 15.2 cm (6 in.) of separation for every

120 V of power.

 Routing field wiring in a grounded conduit can reduce electrical noise.

 If field wiring must cross AC or power cables, ensure that they cross at right

angles.

 If noise persists for a device, try grounding the opposite end of the cable shield

or ground both ends of the shield.
