Explosion Proof LED Light
Instruction Manual
Do not attempt operation until you are familiar with all warnings, precautions, and procedures outlined within this instruction sheet.
Read carefully before operating. Retain these instructions for future reference.
WARNING:
USER SHOULD BE TRAINED IN THE PROPER USE AND MAINTENANCE OF THIS DEVICE. IF WIRING OR LAMP REPLACEMENT
INSTRUCTIONS ARE NOT FOLLOWED EXACTLY, THE HANDLAMP MAY NOT BE SUITABLE FOR THE HAZARDOUS LOCATION INVOLVED.
WHEN HANDLAMP IS CONNECTED TO A POWER SOURCE IN HAZARDOUS AREA, JUNCTION BOX, OR PLUG, AND MATCHING RECEPTACLE
MUST BE SUITABLE FOR HAZARDOUS LOCATION INVOLVED.
WARNING: To prevent ignition of a hazardous atmosphere, the supply circuit should be disconnected when installing, re-lamping or performing any
maintenance on this fixture.
WARNING: When installing this fixture in hazardous locations, check the operating temperature limits prior to installation to be sure it confirms to the
environmental temperature restrictions and NEC classifications. Check the fixture’s metal nameplate for temperature (T) ratings.
WARNING: The globe is tempered glass. Do not scratch or chip. Turn the power off before starting installation, repair or re-lamping.
WARNING: Operate this fixture only at the voltage of your specific supply circuit. Failure to do so will result in damage to the fixture.
WARNING: Substitute components may impair explosion proof safety.
THE GLOBE IS MADE OF TEMPERED GLASS. IF THIS GLASS BECOMES SCRATCHED OR CHIPPED IT SHOULD BE REPLACED IMMEDIATELY.
INSTALLATION
1. Install fixture’s mounting accessory per instructions supplied with the mount (See
Mounting Options). Unscrew and remove the fixture from mount (C).
2. Verify that the supply line voltage and fixture nameplate voltage are compatible.
3. Wire according to wiring instructions in this manual.
4. Make sure the external threads at the top of the fixture tank are free of any dirt, metal
chips or other foreign materials. Apply a thin coat of lubricant to the threads.
5. Close off any open NPT ports.
6. Screw fixture into mount and tighten the set screw.
7. Loosen the set screw for the globe assembly to access pattern switch (A).
8. Enable power to the fixture and toggle switch until desired pattern is selected.
9. Make sure the globe support threads are clean. To prevent galling of threads, apply a
thin coat of lubricant to the male threads. Thread the globe support assembly back
into the fixture tank and turn until there is no gap between the flanges.
10. Tighten the locking screw (A).
11. To install the guard (D) loosen the 4 screws (B), slip the guard over the screws and
rotate it to the locked position. Tighten the screws firmly. The globe assembly can be
removed with the guard installed.
Join or “lap” marks may form during the pouring of molten glass in the globe manufacturing process. It is not unusual for these marks to
become visible. This is a common and normal occurrence for large explosion proof globes and does not affect performance. Take
extreme care not to cross-thread the fixture when installing into mounting accessory. Install fixture by threading into the mounting
accessory; the electrical contacts will automatically engage. Be sure the fixture is tight. This fixture is factory sealed.
Pendant Mounting
1. Thread the fixture onto the conduit, sealing around the conduit using approved NEC
procedures. Flats are provided at the top of the fixture to tighten with a wrench.
2. After securing to the conduit, tighten the set screw.
Wall Mounting
1. Remove the wiring box from the arm and attach box to the mounting surface.
2. Pull leads to the box and through the arm to the wiring chamber.
3. Attach the arm to the wall box.
4. The mounting screws should be tightened in alternate sequence.
Ceiling Mounting
1. Attach fixture to mounting surface using the two mounting tabs provided.

Wiring Instructions
Remove the wiring access plug. For high voltage fixtures, connect neutral to white fixture wire and line to black fixture wire, connect
ground (earth) to ground lug inside the fixture. For low voltage fixtures, connect low voltage (+) to white fixture wire, and low voltage (-)
to black fixture wire. Make all wiring connections accordance with accepted NEC and local wiring procedures for factory sealed fixtures.
Be sure any unused wiring entrances are closed with closure plugs provided.
Maintenance
Following this manual information will extend the lifespan and use of this light in a safe manner.
KEEP THIS LIGHT AND ALL ACCESSORIES OUT-OF-REACH OF CHILDREN.
Turn OFF the supplying circuit before opening fixture for re-lamping. To re-lamp loosen the locking screw and remove the globe support
assembly.
The globe support assembly disengages after approximately 3 turns. Access to the fixture internal lamp area is only necessary for
changing the flash pattern. Clean the threads and apply a thin coating of lubricant before reassembling.
To maintain maximum light output, the fixture should be cleaned periodically. Maintenance procedures sometimes require fixtures to be
hosed down for good housekeeping.
The supply circuit must be turned OFF and the fixture globe must be allowed to cool to the ambient room temperature before cleaning.
Only mild, non-abrasive cleaning agents should be used. These periodic cleaning procedures are important to prevent the accumulation
of dust and dirt which will impair the light output of the fixture. The glass globe should be regularly inspected for scratches and chips
and, if damaged, the entire globe support assembly must be replaced.
