Exp Cord Cap
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.
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.
