INSTALLATION AND MAINTENANCE MANUAL DUROSITE STW SERIES Document No: 9100-127-1508-99 Rev E JULY 2015 FOR USE WITH MODEL NUMBERS: (WHERE “X” IS A PLACE HOLDER FOR ANY CHARACTER) STWXX2X These instructions contain important safety information, read and follow them carefully. Dialight will not accept any responsibility for injury, damage or loss which may occur due to incorrect installation, operation or maintenance. Document No: 9100-127-1508 -99 Rev E 1: Introduction This STW Series light is designed for illumination of industrial and commercial 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 supply allows it to be used from any nominal 100V-277V, 60/50Hz single phase AC supply without any variation in light output. 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 in-line with the white wire (normally the Neutral) a fuse may be connected in series with it if required. Series STW is suitable for use in the following locations: SUITABLE FOR WET LOCATIONS UL 1598/ 1598 A 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. NEVER open or attempt to open LED luminaire. NO user serviceable parts inside Warning: 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 recommend by the manufacture may cause an unsafe condition DO NOT use this equipment for other than intended use Page 2 of 7 1501 Route 34 South, Farmingdale, NJ 07727 Tel: (732) 919-3119 Fax: (732) 751-5778 www.dialight.com Document No: 9100-127-1508 -99 Rev E 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 Dialight replacement parts are to be used when unforeseen maintenance is required Must install using NEMA 4x rated components to maintain rating. Warning: POLYCARBONATE LENS SUSCEPTIBLE TO CHEMICAL ATTACK AVOID USE WITH: o Strong Bases Ammonium Hydroxide Sodium Hydroxide Potassium Hydroxide o Halogenated solvents Methylene Chloride Chloroform Carbon Tetra Chloride o The Ketones Acetone Acetonitrile Ethyl Acetate Methyl Ethyl Ketone – (MEK) o Also Avoid Use With Benzene Benzyl Alcohol Lacquer Thinner Mineral Spirits Jet Fuel Dimethyl Sulfoxide Diethyl Ether Carbon Disulfide Eylene Urea ***NOTE: This list is not comprehensive and is not meant to be so. It is up to the end user to test and verify the product is suitable for use in a given location*** º For supply connections use wire rated for at least 90 C Models STW are factory supplied with 10feet (3meters) of cable. If longer lengths of cables are required a minimum of 18awg (1.5mm diameter) is required. It is recommended that to ensure moisture does not flow through the cable a loop in the cord should be implemented where possible during installation. If this is not practical for the install than necessary precautions should be taken to prevent moisture entering the conduit thus entering the fixture. Recommended mounting height: 8 feet to 24 feet (2.4 m to 7.3 m) Page 3 of 7 1501 Route 34 South, Farmingdale, NJ 07727 Tel: (732) 919-3119 Fax: (732) 751-5778 www.dialight.com Document No: 9100-127-1508 -99 Rev E Pendent Mount Installation Steps: RECOMMENDED FOR USE WITH 360° AND WALKWAY OPTICS. For best optical performance Dialight Corportation recommends mounting a unit with 360° and Walkway Optics parallel to the floor. For maximum long term reliability and light output, the light must be installed in free air. o The STW Series 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 STW series 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 pipe sealant). o NOTE: 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 the cable or conduit and entering the fixture. o Insert 1/4-20 set screw in order to secure the fixture to the conduit. Connect power cable conductors as follows: o For single phase (100 / 277 VAC): Green wire connects to Safety Ground. White wire connects to Neutral Black wire connects to Live Restore power and verify operation. Stanchion Mount Installation Steps: RECOMMENDED FOR USE WITH 180° AND WALKWAY OPTICS. For best optical performance Dialight Corportation recommends mounting a unit with 180° optics at a 45° angle with respect to the vertical mounting pole or wall. For best optical performance Dialight Corportation recommends mounting a unit with Walkway Optics parallel to the floor.

For maximum long term reliability and light output, the light must be installed in free air. o The STW Series 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 STW series fixture is threaded for ¾” 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 pipe sealant). o NOTE: 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 the cable or conduit and entering the fixture. o Insert ¼-20 set screw in order to secure the fixture to the conduit. Connect power cable conductors as follows: o For single phase (100 / 277 VAC): Green wire connects to Safety Ground. White wire connects to Neutral Black wire connects to Live Restore power and verify operation. …CONTINUED NEXT PAGE Page 4 of 7 1501 Route 34 South, Farmingdale, NJ 07727 Tel: (732) 919-3119 Fax: (732) 751-5778 www.dialight.com Document No: 9100-127-1508 -99 Rev E WIRE DIAGRAM FOR USE WITH STW SERIES LUMINAIRE ANTI-ROTATION SCREW ¾” NPT INLET POTTING INSTALLED INTO BASE OF ENTRANCE (NOT SHOWN) Page 5 of 7 1501 Route 34 South, Farmingdale, NJ 07727 Tel: (732) 919-3119 Fax: (732) 751-5778 www.dialight.com Document No: 9100-127-1508 -99 Rev E 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. 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 COOLING FINS POLYCARBONATE LENS Page 6 of 7 1501 Route 34 South, Farmingdale, NJ 07727 Tel: (732) 919-3119 Fax: (732) 751-5778 www.dialight.com Document No: 9100-127-1508 -99 Rev E 4: Specifications Nominal AC Supply Voltage 100-277VAC, 50-60Hz, single phase Power consumption 70W nominal ([STW8, STW9 SRS) 55W nominal ([STW4, STW5 SRS) 43W nominal ([STW2, STW3 SRS) Operating temperature range -40°F to +149°F [-40°C to +65°C] Power factor >0.95 ATHD <5% @120VAC <10% @230/240VAC <12% @277VAC Dimensions (Height x Diameter) 10.7” x 9.7” x 6.6” [271mm x 246mm x 167mm] Weight 10.0 lbs [4.5 kg] Intertek Certified to UL 1598/ 1598A and CAN/CSA C22.2 No. 250 DIMENSIONS ARE FOR REFERENCE ONLY.
