50W Explosion Proof LED Flood Light Fixture
C1D2, C2D1/C2D2 - Serviceable Junction Box
Instruction Manual
This explosion proof light is designed for illumination of industrial locations. It uses the latest in
solid state lighting technology for long life, low maintenance and high efficiency.
The unique design focuses the light where it is needed, giving improved efficiency over a
conventional HID luminaire.
An internal, universal input, power-factor-corrected switch-mode supply allows it to be used from any
nominal 100-277V AC 50/60 Hz or 11-25 Volts AC/DC power supply (depending on model) without
any variation in light output.
WARNING
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 connected to a wiring system with an equipment-grounding conductor.
To avoid explosion:
•Make sure the supply voltage is within the luminaires’ voltage rating.
•Ensure the marked T rating is less than the ignition temperature of the Hazardous
Atmosphere.
•Do not operate in ambient temperatures above those indicated on the luminaire nameplate.
•Do not operate if the lens is cracked or damaged. All fasteners should be properly seated.
For supply connections, use wire rated for at least 110°C
Recommended mounting height is 25-40 feet.
MOUNTING
This fixture offers an adjustable surface mounting system that allows this fixture to be mounted to any
flat surface including walls and ceilings. A single ½-13 bolt is used to mount the fixture to the
surface.

WIRING (see attached wiring diagram)
This unit comes preconfigured with selected voltage, and beam
angle. Position device near work area for operation. Run cable to
nearby power source. Insert and twist-lock explosion-proof plug
into a compatible receptacle within the hazardous environment.
See plug operation below.
PLUG OPERATION
Electrical connection between plug and compatible receptacle is
accomplished after plug fully inserts into receptacle and rotated
clockwise.
1. Lift receptacle door and locate polarization on mating plug
pin and receptacle face. Insert plug straight all the way into
receptacle until it cannot go further.
2. Rotate plug clockwise limit (37º), this closes internal
contacts and completes circuit. This also mechanically
locks plug into receptacle so it cannot be pulled out.
3. To remove plug, push plug inward and turn to
counterclockwise, pull plug straight out.
Follow all applicable NEC, local, and state electrical codes.
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 cooking 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.
