NOTICE: These instructions contain important safety information, read and follow them carefully.

Larson Electronics will not accept any responsibility for injury, damage or loss which may occur due to

incorrect installation, operation or maintenance.

INTRODUCTION:

This LED 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 optical design focuses light downward to 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 100V-277V supply without any variation in light output.

WARNINGS:

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.

DO NOT let power cord touch hot surfaces.

DO NOT mount near gas or electric heaters.

Equipment should be mounted in locations and at heights where it will not be subjected to

tampering by unauthorized personnel.

The use of accessory equipment not recommended by the manufacture may cause an unsafe

condition.

DO NOT use this equipment for other than intended use.

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 nameplate.

Do not operate if the lens is cracked or damaged. All fasteners should be properly seated.

WARNING –Explosion Hazard –Substitution of components may impair suitability for Class I

Division 2 and Class II Division 1

Explosion Hazard –Do not disconnect equipment unless power has been switched off or the

area is known to be non-hazardous.

INSTALLATION

WARNING: The technical data indicated on the luminaire are to be observed.

Changes to the design and modifications of the luminaire are not permitted.

Only genuine Larson replacement parts are to be used when unforeseen maintenance is

required. Consult factory at www.larsonelectronics.com or call 1-800-369-6671 for

assistance.

For supply connections use wire rated for at least 90°C

Conduit thru Mount

For maximum long term reliability and light output, the light must be installed in free air.

oThe fixtures design incorporates an over-temperature control circuit that reduces input

power should internal temperatures reach a maximum level. In this event, light output

may be reduced.

The fixture is threaded for ¾” NPT, at the center and each end of the power supply housing, in

order to be assembled to conduit.

oAttach conduit. Use conductive pipe sealant for all fittings and conduit.

oWarning: If there is moisture present or chance of it in the conduit system than

necessary precautions should be taken by the installer to prevent the moisture from

entering thru cable or conduit and entering the fixture. Failure to comply with the above

could void warranties.

oFixture is factory wired for both Pendant and Through wiring. Remove the power supply

covers to attach incoming power to the white wire and black wire leads with wire nuts

at the end of the fixture. Attach the ground wire to the green ground lead supplied at

the end of the fixture. Repeat this procedure for the opposite end. Ensure that the o-

rings are properly seated in the grooves; reattach the cover using the screws previously

removed. Tighten all screws to 15 in/lbs (1.75NewtonM’s).

oConnect incoming power as follows:

-Green to safety ground lead supplied at the end of the fixture

-Neutral to white

-Line to black

oRestore power and verify operation.

MAINTENANCE

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 fixture. Risk of electric shock. Removal of the lens will void

the warranty.

1. We suggest performing visual, mechanical and electrical inspections on a regular basis. We

suggest 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. If the lens requires periodical cleaning to ensure continued photometric performance, clean the

lens with a damp, non-abrasive lint-free cloth. If not sufficient, use mild soap and water.

3. Inspect the outside of the luminaire housing to ensure that they are free of any obstructions or

contamination (i.e. excessive dust build-up). Clean with non-abrasive cloth if needed.

4. Do not operate if the lens is cracked or damaged. All fasteners should be properly seated.

5. NOTE: Screws on other wiring compartments are factory torqued and should not be tampered

with during installation or maintenance.
