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.
