ICON 100 SERIES INSTALLATION GUIDE
4.4 Electrical Wiring
We would recommend protecting the controller power supply from
electromagnetic disturbances, voltage peaks, etc. This can be easily done
while wiring by following the instructions below:
•
separate the power supply cables of the compressor, motors, etc.
from those of the controller;
•
keep the probe cables, the controller power supply cables, and the
load power supply cables separate and sufficiently far away from
each other, so they do not cross or form spirals.
4.5 Applications in Critical Environments
When used in particularly critical industrial environments the following
precautions can also be useful:
•
Use mains network filters to reduce disturbances at the controller
power supply, as well as filters for the loads in order to attenuate
disturbances at the controller relay outputs;
•
Use screened probe cables connected to the grounding system, if the
previous indications are not sufficient;
•
In the event of strong radio disturbances screen the entire device with
a metallic screen and connect it the grounding system.
