3-2 Wire Your Controller
• Separate wiring by signal type. Bundle wiring with similar electrical
characteristics together.
• Separate input wiring from output wiring.
• Label wiring to all devices in the system. Use tape, shrink-tubing, or
other dependable means for labeling purposes. In addition to labeling,
use colored insulation to identify wiring based on signal characteristics.
For example, you may use blue for dc wiring and red for ac wiring.
Wire without Spade Lugs
When wiring without spade lugs, it is recommended to keep the finger-safe
covers in place. Loosen the terminal screw and route the wires through the
opening in the finger-safe cover. Tighten the terminal screw making sure the
pressure plate secures the wire.
TIP
Do not run signal or communication wiring and
power wiring in the same conduit. Wires with
different signal characteristics should be routed by
separate paths.
