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.
