Routing data wires
Routing data wires in the same conduit as, or beside AC power cables, can cause electrical
interference, erratic readings, and/or improper control. Data wires include all of the following:
Temperature probe and humidity sensor cables
Actuator feedback (potentiometer) wires
Data communication wires, including RS-232/RS-485
Any cable or wire that does not provide AC power
Guidelines for routing data wires
Do not run the wires in the same conduit as AC power cables.
Do not run the wires beside AC power cables or near electrical equipment.
When crossing other cables or power lines, cross them at a 90-degree angle.
If in doubt,
do not run any wire or cable that is not an AC-power wire inside the same conduit or
beside other AC-power wires.
