a powerful and energy efficient alternative to traditional hazardous location luminaries. This LED panel mount fixture is
ETL listed Class I Divisions 1 & 2, Class II Divisions 1 & 2,and is approved for use within paint spray booths. Cree LED
technology and compact design makes this lamp an excellent replacement upgrade option for paint booths and
hazardous locations where flammable chemical/petrochemical vapors are present.
WIRING
Standard pigtail(flying leads) wiring
We strongly encourage a licensed electrician install this product,in all locations especially in outdoor areas
where weatherproofing may be required. Universal voltage driver permits operation at 100V - 277V AC, 50 or 60Hz
except those factory ordered with low voltage 11V to 25V AC/DC.
Warning: Check product label for correct input voltage!
Attach supply line wires to the appropriate light fixture wires as
shown in thediagram 
Secure each pair of wires according to the diagram. Utilize a junction box
or similar device and take precautionary steps for
weatherproofing all connections if installed in a location where water
may come in contact with the unit. Ensure the unit is properly grounded
and that wiring is done according to all local and national electrical/building
codes.
This unit comes preconfigured with cord whip and selected color temp. Once mounted, plug cord into compatible
receptacle with correct voltage. Fixture available in 100-277 Volts AC, 50/60Hz or 11-25 Volts AC/DC and are not
interchangeable. Please check product nameplate for correct voltage!
WARNING: CHECK NAMEPLATE FOR
PROPER VOLTAGE. DAMAGE FROM
IMPROPER VOLTAGE WILL VOID
WARRANTY. FIXTURE AVAILABLE IN
VARIOUS VOLTAGES SELECTED
UPON PURCHASE.

MOUNTING
This fixture offers recessed panel mounting. Fixture is not intended to be suspended.
1. Make sure power is turned off at the source to the location at
which you are installing the fixture.
2. Remove existing troffer if applicable.
3. Place the troffer in the drop-ceiling or flat surface cut-out. If
utilizing drop ceiling installation, operators may choose to
penetrate the flanges of the fixture to secure to the ceiling.
When installing on flat surface cutouts, operators will be
required to drill holes in the fixture flange to secure the fixture
to the surface. Use minimum of 3/8" anchor bolts to secure the
fixture to flat surfaces. When drilling holes, ONLY drill holes in
the outer flange of the fixture, minimum 2" distance between
LED assembly and drilled holes. Drilling holes for anchor bolts
does not void certification.
4. Using provided wire, run provided wiring harness from the
back of the fixture inside of 3/4" rigid conduit. Secure the 3/4"
conduit to the back of the 3/4" NPT hub provided on the back
of the light fixture. Make remaining electrical connections
within a junction box that is approved for the environment
where the light fixture is being installed. This light fixture is
factory sealed and does not need a seal-off. Refer to wire
diagram. All local and national electrical/building codes must
be followed when installing this fixture in hazardous areas. If
unaware, contact local authority.
5. When complete, ensure voltage matches fixture nameplate
and return power back to the source.
Installation is complete.
MAINTENANCE
Caution: 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.
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.
4. Do not operate if the lens is cracked or damaged. All fasteners should be properly seated.
