Cable Shields
Do not ground the shield to earth ground or to the control
module’s power ground. The PROT485 and the individual
so that there are no ground loops. If the voltage on the
shield becomes too great relative to the earth ground, then
PROT485 or on the control modules.
Noise Avoidance
Avoid running communication wires or sensor input wires
next to AC power wires or the control module’s relay
output wires. These can be a source of noise that can
Common sources of noise are:
Spark ignitors
Radio transmitters
Variable speed drives
Generators
Relays
Transformers
If noise is a problem and the wiring cannot be moved,
use ferrite clamp-on chokes on the cabling to improve
signal quality.
Induction heaters
Video display devices
Lamp dimmers
Fluorescent lights
Parallel runs with power lines
