WIRING
All wiring must comply with applicable electrical codes and
ordinances, or as specified on installation wiring diagrams.
WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property
damage.
Disconnect power supply before beginning wiring, or
making wiring connections, to prevent electrical shock
or equipment damage.
CAUTION
Equipment Damage Hazard.
Electrostatic discharge can short equipment
circuitry.
Ensure that you are properly grounded before
handling the sensor.
Prepare wiring as follows:
1. Strip 1/2 in. (13 mm) insulation from the conductor.
2. Cut a single wire to 3/16 in. (5 mm). Insert the wire in
the required terminal location and tighten the screw.
3. Pull on each wire in all terminals to check for good
mechanical connection.
