INSTALLATION AND MAINTENANCE MANUAL DUROSITE™ SERIES LED LOW BAY Document No: 9100-127-1434-99 Rev B April 2011 MODEL #’s LBW1X1X Document No: 9100-127-1434-99 Rev B 1: Introduction This Low Bay 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 power-factor-corrected switch-mode supply allows it to be used from any nominal 100V277V, 50/60Hz AC supply without any variation in light output. Models LBW1X1X are suitable for use in the following locations: • • Wet Locations as per UL 1598 Outdoor Type (Salt Water) as per UL 1598A Note: Save these instructions for future reference. 2: Installation 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. Warning: 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. Warning: • • Make sure the supply voltage is the same as the rated luminaire voltage. Do not operate in ambient temperatures above those indicated on the luminaire nameplate. Recommended mounting height: 12-20 feet Page 2 of 5 1501 Route 34 South, Farmingdale, NJ 07727 Tel: (732) 919-3119 Fax: (732) 751-5778 www.dialight.com Document No: 9100-127-1434-99 Rev B Pendent Mount Installation Steps: • • • • For maximum long term reliability and light output, the light must be installed in free air. o The Low Bay fixture design incorporates an over-temperature control circuit that reduces input power should internal temperatures reach a maximum level. As a result, light output may be reduced. The Low Bay fixture is threaded for 3/4” NPT in order to be assembled to conduit. o Calculate and measure required conduit length. o Feed the power cable through the conduit and into the junction box. o Attach the fixture to the conduit (using Teflon tape or pipe sealant). o Insert 1/4-20 anti-rotation screw in order to secure the fixture to the conduit. Connect power cable conductors as follows: o Green wire connects to Safety Ground. o White wire connects to Neutral o Black wire connects to Live Restore power and verify operation. Interfacing to an Occupancy Sensor: The Dialight Low Bay fixture is ideally suited for control by an occupancy sensor in order to maximize energy savings based on its instant-on behavior and low power consumption. Instructions for connecting the High Bay fixture to an occupancy sensor are listed below. WARNING: TO BE INSTALLED AND/OR USED IN ACCORDANCE WITH APPROPRIATE ELECTRICAL CODES AND REGULATIONS. WARNING: CONTROLLING A LOAD IN EXCESS OF THE SPECIFIED RATINGS OF THE OCCUPANCY SENSOR COULD DAMAGE THE UNIT AND POSE RISK OF FIRE, ELECTRIC SHOCK, PERSONAL INJURY, OR DEATH. CHECK LOAD RATINGS TO DETERMINE THE UNIT’S SUITABILITY FOR YOUR APPLICATION. NOTE: SEE OCCUPANCY SENSOR INSTALLATION INSTRUCTIONS FOR ADDITIONAL INFORMATION.

Multiple fixtures may be connected to a sensor, as long as the rated load of the sensor is not exceeded. 4) Restore power at circuit breaker or fuse. 5) Verify operation of system. If the light will not turn on, check the operation of the fixture and sensor individually, and check that the wiring is done correctly. If the light will not turn off or it turns off and on quickly, see the sensor’s installation instructions for further guidance. 3: 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 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. Do not use an abrasive, strong alkaline or acid cleaner as damage may occur. 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. Page 4 of 5 1501 Route 34 South, Farmingdale, NJ 07727 Tel: (732) 919-3119 Fax: (732) 751-5778 www.dialight.com Document No: 9100-127-1434-99 Rev B 4.
