INSTALLATION AND MAINTENANCE MANUAL Vigilant SERIES LED HIGH BAY Document No: 9100-127-2275-99 Rev B August 2015 IMPORTANT: Please read carefully before installation and retain for future reference Document No: 9100-127-2275-99 Rev B 1: Introduction This High 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 120V277V, 50/60Hz AC supply without any variation in light output. This unit is suitable for use in the following locations: Dry locations only as per UL 1598 Note: Save these instructions for future reference. “THE ELECTRICAL CHARACTERISTICS OF THE LIGHT FIXTURE ARE THOSE INDICATED ON THE PRODUCT LABEL” 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. Surface temperatures will become very hot in some operating conditions. End user and installers are responsible for installing in an appropriate and safe environment. Recommended mounting height: 60-100 feet Page 2 of 6 1501 Route 34 South, Farmingdale, NJ 07727 Tel: (732) 919-3119 Fax: (732) 751-5778 www.dialight.com Dialight de México S.R.L de C.V.

As a result, light output may be reduced. The junction box for this high 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 junction box to the conduit (using Teflon tape or pipe sealant). o Insert 1/4-20 anti-rotation screw to secure the fixture to the conduit. (35-40 in-lb) o Hook fixture onto junction box as shown in figure 2 Connect power cable conductors as follows: o Green wire and ground connect to ground boss indicated in figure 1. o White wire connects to Neutral o Black wire connects to Live o When using 208V (two 120V phases) connect the black wire to one phase and the white wire to the other phase. Since the light fixture does not have an internal fuse on the white wire (as it is normally the neutral), a fuse may be connected in series with the white wire if required. Engage locking nut as pictured in figure 3. Torque nut to 50-55 in-lb. Restore power and verify operation.

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 lenses 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. 4: Specifications Nominal AC Supply Voltage 120-277VAC, 50/60Hz single phase Power consumption 483W nominal Operating temperature range Power factor ATHD Dimensions (Height x Diameter) Weight -40°C to +65°C [-40°F to +149°F] >0.95 <10% 16” x 24” [40.6cm x 61.0cm] 38 lbs.
