WIRING
(see attached wiring diagram)
This unit comes preconfigured in the selected voltage, beam spread, and explosion proof cord cap.
Run cord from light and plug into matching receptacle. Follow all applicable local, state, and National
Electrical Code for the hazardous area!
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.
WARNING:
ELECTRICAL POWER SUPPLY MUST BE “OFF” BEFORE AND DURING INSTALLATION AND
MAINTENANCE. INSTALLATION AND MAINTENANCE PROCEDURE MUST BE PERFORMED BY A TRAINED AND
COMPETENT ELECTRICIAN.
If any part of the plug appears to be missing, broken, or show signs of damage—discontinue use immediately! This
condition could cause serious or fatal personal injury due to electrocution and/or equipment damage. Repair with the
proper replacement part(s) before continuing service.
During the inspections, perform the following steps:
1.
Inspect all contact wire terminals for tightness and re-torque if necessary. NOTE: Discoloration due to excessive
heat is an indicator of potential issues and should be thoroughly investigated and repaired as necessary.
2.
Explosion Proof Plugs: Check grounding and bonding for correct installation. Secure connections and retorque if
necessary.
3.
Check gaskets for deterioration and replace if necessary.
4.
Clean exterior surfaces to ensure the nameplates remain legible.
5.
Inspect cable grip tightness to ensure proper cord/cable gripping.
6.
Inspect all parts and replace those which are broken or excessively worn.
7.
Check the contacts for signs of excessive arcing or burning and replace if necessary.
USE AND CARE
Unauthorized modification may impair the function and/or safety of the extension cord and could affect the life of the
equipment. Always check damaged or worn out parts before using the unit. When extension cord is not in use, store it in a
secure place. Inspect for good working condition prior to storage and before re-use.
