Explosion Proof LED Light Light Fixture
Instruction Manual
Do not attempt installation until you are familiar with all warnings, precautions, and procedures outlined within
this instruction sheet.
WARNING:
READ CAREFULLY BEFORE INSTALLING FIXTURE. RETAIN THESE INSTRUCTIONS FOR FUTURE
REFERENCE. CRITICAL SAFETY INSTRUCTIONS:
•To avoid the risk of fire, explosion, or electric shock, this product should be installed, inspected, and
maintained by a qualified electrician only, in accordance with all applicable electrical codes.
To avoid electric shock:
•Be certain electrical power is OFF before and during installation and maintenance.
•Luminaire must be supplied by a wiring system with an equipment grounding conductor.
To avoid burning hands:
•Make sure lens and housing are cool when performing maintenance.
To avoid explosion:
•Make sure the supply voltage is the same as the luminaire voltage.
•Do not install where the marked operating temperatures exceed the ignition temperature of the
hazardous atmosphere.
•Do not operate in ambient temperatures above those indicated on the luminaire nameplate.
•Use proper supply wiring as specified on the luminaire nameplate.
•All gasket seals must be clean.
•Before opening, electrical power to the luminaire must be turned off. Keep tightly closed when in
operation.
Refer to the luminaire nameplate for specific classification information, maximum ambient temperature
suitability, and corresponding operating temperature (TCode).
Luminaire construction is designed for use indoors and outdoors in marine and wet locations, where moisture,
dirt, corrosion, vibration, and rough usage may be present.
MOUNTING
1. Mount the cover module in its support position.
2. Ceiling and wall mount: mark and drill desired location on
mounting surface. Secure with 1/4" (6mm) bolts or lag
screws (not provided).
3. Pendant, stanchion mount: securely thread onto the
appropriate NPT size conduit. Tighten set-screw located in
the conduit hub. See Figure 1.
4. Thread lubricant must be added to the conduit threads to
prevent water from entering the fixture.
WIRING (Voltage: 120-277VAC 50/60 Hz)
1. Pull field wiring into cover module.
2. Close all unused conduit entries with conduit plugs provided. To prevent galling and to ensure water-
tightness, lubricate conduit plugs with lubricant before installing, and secure wrench-tight with at least
five (5) full threads engaged (42-52 ft.-lb. for 3/4” plugs, and 58-68 ft.-lb. for 1” plugs).
3. Hang LED luminaire on the cover module hinge hook. See Figure 2a.

4. Connect supply wires to luminaire wire leads (or terminal blocks) per the
attached wiring diagrams using methods that comply with all applicable
codes. See Figure 2b. Tighten all electrical connections.
5. Close driver housing onto cover module, making sure that all wires are
safely inside driver. Tighten captive closing screw to 30 in.-lbs. (3.4 N-m).
Ensure two (2) bosses on driver housing are in contact with cover module.
6. Turn power on.
MAINTENANCE
1. Perform visual, electrical, and mechanical inspections on a regular basis. The environment and
frequency of use should determine this. However, it is recommended that checks be made at least
once a year. We recommend an Electrical Preventive Maintenance Program as described in the
National Fire
2. Protection Association Bulletin NFPA No. 70B: Recommended Practice For Electrical Equipment
Maintenance (www.nfpa.org).
3. The lens should be cleaned periodically to ensure continued lighting performance. To clean, wipe the
lens with a clean, damp cloth. If this is not sufficient, use a mild soap or a liquid cleaner such as
Collinite NCF or Duco #7. Do not use an abrasive, strong alkaline, or acid cleaner. Damage may result.
4. Visually check for undue heating evidenced by discoloration of wires or other components, damaged
parts, or leakage evidenced by water or corrosion in the interior. Replace all worn, damaged, or
malfunctioning components, and clean gasket seals before putting the luminaire back into service.
5. Electrically check to make sure that all connections are clean and tight.
6. Mechanically check that all parts are properly assembled.

INSTALLATION CHECKLIST
Verify sufficient lubricant is on conduit plugs
(recommend approximately 1/8” bead
around the first thread of plug) and that all
unused conduit entries on the cover module
are closed with lubricated plugs.
Verify conduit plugs are installed to at least
five (5) full threads into the cover module
conduit entries.
Verify installed conduit plugs are torqued to
42-52 ft.-lbs. for 3/4” plugs and 58-68 ft.-lbs.
for 1” plug.
Verify supply wires are connected to
luminaire wire leads (or terminal block) per
wiring diagrams.
Verify all electrical connections are
tightened.
Verify all wires are safely and neatly inside
driver housing and not on top of wire
terminal. Close driver housing onto cover
module.
Verify captive closing screw is tightened to
30 in.-lbs. (3.4N-m) and two (2) bosses on
driver housing are in contact with cover
module.
