INSTRUCTIONS
Industrial Luminaires
Installation and Maintenance
READ THOROUGHLY BEFORE INSTALLING
SAVE THESE INSTRUCTIONS FOR FUTURE USE
WARNING
Risk of electric shock
• Turn power off before servicing
CAUTION
Risk of burn
• Do not touch operating luminaire
GENERAL
This luminaire is designed for indoor applications only, and should be installed and maintained according
to these instructions.
NOTE: The maximum fixture ambient temperature rating is the LESSER of the ratings indicated on the
ballast and optical assemblies.
All luminaire refractors and lenses made of acrylics or polycarbonates will yellow over time with exposure
to heat and ultraviolet (UV) light. The rate of yellowing is determined by the specific material, any additives
and coatings, the operating temperature, and the amount of UV exposure. Yellowing can reduce the light
output and lower the impact resistance of acrylic or polycarbonate opticals.
In no case should the maximum lamp wattage listed for the luminaire be exceeded. Contact the factory
for more information.
UNPACKING
This luminaire has been properly packed to avoid damage during transit. Inspect the luminaire to confirm
there is no damage. Do not install a damaged luminaire or damaged luminaire components.
NOTE: The luminaire is supplied with a hanger hub and locking nut which are threaded together, and
are included in the ballast housing carton.

CONDUIT MOUNTING
1. Fasten the mounting plate (minimum of five full turns) to a 3/4-inch conduit by threading the
mounting plate onto the conduit. See Figure 1.
2. Tighten the set screw to lock the mounting plate to the conduit.
3. Loosen the set screw on the top corner of the ballast housing.
4. Loosen the wiring box door screws on the ballast housing to allow the wiring box door to pivot.
5. Pivot the wiring box door 180 degrees to allow the mounting plate room to slide onto the ballast
housing.
6. Slide mounting plate onto ballast housing, making sure that the upper rim of the ballast housing
slides into the rails of the mounting plate. (Figure 2)
7. Tighten the set screw on the top corner of the ballast housing so that the mounting plate cannot
back out.
8. After wiring is complete, pivot the wiring box door back into the original position and tighten the
two wiring box door screws.
FLEXIBLE MOUNTING
If flexible mounting accessories (hook or loop) are supplied separately, follow the instructions above for
conduit mounting .
CAUTION: If this instruction is not followed damage to the mounting parts can occur causing the
fixture to fall. When using hook or loop fixture mounting, do not apply luminaire weight when the
mating parts are as shown in Figure 3. Do not apply any twisting action to the hook and loop assembly.
When properly installed the hook and loop assembly is shown in Figure 4.
WET LOCATION OPTION
(Water tight seal bwteen conduit and hub)
1. Fasten hanger hub securely (minimum of five full turns) to 3/4-inch conduit by threading locking nut
and hanger hub assembly onto conduit. See Figure 5.
