5.1 Field Wiring
+ Note: In the process of wiring the modules, route all signal wires as far as possible from potential sources
of electrical noise, such as motors, transformers, etc., (especially ac devices). As a general rule, allow 15.2
cm (6 in) of separation for every 120V of power. Signal wires must never share the same conduit with ac
wiring. Also, when you must route signal wires past ac wiring, do so at right angles.
