2. Intended Field ofApplication
The Universal Flameproof LED Lighting, Model THT-P1202 is intended for using in gas explosive
atmospheres (Zone 1 and Zone 2) and dust explosion hazards (Zone 21 and Zone 22). The use in other
potentially explosive atmospheres does not correspond to the designated use and is therefore not allowed.
The apparatus is designed for using in indoor and outdoor environments.

WARNING
uTo reduce the risk of ignition due to electrostatic discharge, avoid contact with the luminaire while
an explosive atmosphere is present. Clean only with a damp cloth.
uContact manufacturer for information on the flameproof joints.
uInstructions for safety (i.e. putting into service, use, assembling, maintenance, installation,
adjustment, and mounting).
uTools used for the equipment.
uInstructions relevant to the safe installation, use, and operation of the equipment shall be in both
English and French (for Canada).
uTo avoid personal injury, disconnect power to the light and allow the unit to cool down before
performing maintenance.
uPerform 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. Frequency of use and environment should determine this. It is recommended to follow
an Electrical Preventive Maintenance Program as described in the National Fire Protection
Association Bulletin NFPA No. 70B: Recommended Practice for Electrical Equipment Maintenance.
uThe lens should be cleaned periodically to ensure continued lighting performance. Clean the lens
with a clean, damp, non-abrasive, lint-free cloth. If this is not sufficient, use a mild soap or a liquid
cleaner. Do not use an abrasive, strong alkaline or acid cleaner as damage may occur.
uInspect the cooling fins on the luminaire to ensure that they are free of any contamination (i.e.
excessive dust build-up). Clean with a non-abrasive cloth if needed.
uElectrically check to make sure that all connections are clean and tight.
uMechanically check that all parts are properly assembled.
uMaintenance work is not permitted on flameproof enclosures. Repairs are only to be carried out by
the manufacturer. Unauthorized repair shall cause the manufacturer’s liability and warranty
expires.
