SHOCK, PERSONAL INJURY, OR DEATH. CHECK LOAD RATINGS TO DETERMINE THE UNIT’S
SUITABILITY FOR YOUR APPLICATION.
NOTE:
SEE OCCUPANCY SENSOR INSTALLATION INSTRUCTIONS FOR ADDITIONAL
INFORMATION.
1) WARNING: TO AVOID FIRE, SHOCK OR DEATH, TURN OFF POWER AT CIRCUIT BREAKER
OR FUSE AND TEST THAT THE POWER IS OFF BEFORE WIRING.
2) Install occupancy sensor as per sensor instructions to provide desired coverage of area.
3) Connect luminaire wires per wiring diagram as follows: Black lead to load of the occupancy
sensor, White lead to the line (neutral), Green lead to earth ground. Multiple fixtures may be
connected to a sensor, as long as the rated load of the sensor is not exceeded.
4) Restore power at circuit breaker or fuse.
5) Verify operation of system. If the light will not turn on, check the operation of the fixture and
sensor individually, and check that the wiring is done correctly. If the light will not turn off or turns
off and on quickly, see the sensor’s installation instructions for further guidance.
3: Maintenance
• To avoid personal injury, disconnect power to the light and allow the unit to cool down before
performing maintenance.
Warning: No user serviceable parts inside of fixture. Risk of electric shock. Removal of the lens
will void the warranty.
1) Perform visual, mechanical and electrical inspections on a regular basis. We recommend routine
checks to be made on a yearly basis. Frequency of use and environment should determine this. It
is recommended to follow an Electrical Preventive Maintenance Program as described in NFPA
70B: Recommended Practice for Electrical Equipment.
2) The lens should be cleaned periodically as needed to ensure continued photometric performance.
Clean the lens with a damp, non-abrasive, lint-free cloth. If not sufficient, use mild soap or a liquid
cleaner. Do not use an abrasive, strong alkaline or acid cleaner as damage may occur.
3) Inspect the cooling fins on the luminaire to ensure that they are free of any obstructions or
contamination (i.e. excessive dust build-up). Clean with a non-abrasive cloth if needed.
