WIRING
CAUTION
Electrical Shock or Equipment Damage
Hazard.
Can shock individuals or short equipment
circuitry.
Disconnect power supply before installation.
CAUTION
Erratic System Operation Hazard.
Failure to follow proper wiring practices can
introduce disruptive electrical interference
(noise).
Keep wiring at least one foot away from large
inductive loads such as motors, line starters,
lighting ballasts, and large power distribution
panels.
Shielded cable is required in installations where
these guidelines cannot be met.
Ground shield only to grounded controller case.
IMPORTANT
All wiring must agree with applicable codes,
ordinances and regulations.
Connect low voltage wiring from the sensor to the
appropriate system component terminals using 1/4 in.
(6 mm) female quick-connectors at both ends. See Fig. 4
and 5.
