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 120V - 277V AC, 50 or 60Hz.
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.
ADJUSTABLE SURFACE MOUNTING BRACKETS
Each bracket is cinched to the bracket mounting peg on each side of the light. The angle of the bracket is set by tightening
two cap screws on either side of the bracket. The cap screws act as a set screw. The bracket itself is mounted via a single
bolt hole at the top the bracket. There are two brackets, one on each end of the light. Once the brackets are mounted to a
surface (ceiling, floor or wall), the light fixture can be removed from the brackets by loosening the cap screws that hold the
bracket to the mounting peg.
SUSPENSION MOUNTING
Pendant mount fixtures hang from the ceiling and are suspended by rigid pipe. Each fixture features a 1/2” NPT junction box
on one end, and a 1/2” NPT adjustable L-bracket on the other end of the fixture. Operators bring rigid pipe down to the
threaded mounting hubs. Wiring is fed down through the rigid pipe to the junction box and tied in to the fixture’s lead wires,
completing the electrical connection. The adjustable L-shape mounting bracket provides support for the opposite end of the
fixture.
INSTALLATIONPRECAUTIONS
Do not install fixture in any classified location where the marked operating temperature exceeds the ignition
temperature of the hazardous atmospheres.
Consult fixture nameplate for the suitability ambient temperature shown on the nameplate.
Refer to fixture nameplate for minimum supply wire temperature rating.
Verify that the supply voltage agrees with fixture rating as indicated on nameplate.
All local and national electrical/building codes must be followed when installing this lighting fixture. For
code interpretation, consult your local authority.
Product must be used only with glass tubes intact and all cap threads fully engaged. Do not use if glass tubes
are cracked or damaged.

Caution: Only use lamp size, type and /or wattage as shown on fixture nameplate.
INSTRUCTIONS FOR INSTALLING
We strongly recommend that only a licensed electrician install this product.
WARNING: Make sure that the power is disconnected before installing. This fixture is extremely heavy and must be
mounted to a surface that can structurally support the load.
NOTE: This fixture requires a minimum of 50 inches of clearance from re-lamp end for lamp replacement. An optional
drop mounting kit that will allow for end to end row mounting is available, please consult factory.
WARNING: Do not let fixture hang on one bracket at any time. Failing to comply can result in breakage of
end casting or mounting bracket, allowing the fixture to fall, which can cause serious injury or death.
The mounting brackets are shipped installed on the
fixture.
Install the brackets to wall or ceiling with two 3/8" bolts
(not supplied) at center measurements.
Fixture is now ready for mounting.
For pendant mounts, see reference image.
It is strongly suggested to use two licensed electricians to proceed with the final mounting of the fixture to avoid any
possible personnel injury or damage to the fixture as the unit weights up to 46lbs (21.0 kg) and will be slightly awkward
to hold in position and attach to brackets mounted on wall or ceiling. Depending on mounting height and scaffolding, a
hydraulic man–lift or two good quality ladders should be used.
INSTRUCTIONS FOR WIRING LAMP
This lamp includes 50ft SOOW cable whip pre-attached from factory.
Once mounted, run cable to compatible receptacle outputting the correct voltage.
Check product label to ensure voltage is correct. This lamp is shipped with
selected voltage from factory which includes either 347-480V AC 50/60Hz.
Wire diagram included for maintenance reference.
WARNING: Fixture must be grounded as required per paragraph 410-21 and article 250 of the National Electric Code
and/or rule 30-500. Failure to properly ground this fixture will create an electrical shock, which can cause serious injury
or death.

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.
