LUSIO® ESSENTIALS SERIES V 2.1 PRODUCT GUIDE
!
IMPORTANT: READ ALL INSTRUCTIONS THOROUGHLY AND CAREFULLY PRIOR TO INSTALLATION OF ESSENTIALS FIXTURES AND
RETAIN FOR FUTURE REFERENCE.
The Essentials Series of commerical and industrial LED highbay fixtures is for non-insulated ceiling applications with
Suspension, pendant (conduit), hook and loop, or surface mount installation methods.
Essentials fixtures are designed for use in 120-277V or 347-480V, 50-60 Hz protected circuits. Size line voltage service wires as required per the National Electrical Code (NEC). Install fixtures in accordance to all applicable building coes and requirements.
For more information or questions regarding the installation or use of the Essentials fixture, call 913-851-3000.
WARNING
• Only qualified personnel should install, inspect and maintain this product in accordance with all applicable building and electrical codes.
• To avoid electric shock: disconnect electrical power (Line power) before and during installation and maintenance.
• Verify supply voltage is same as the rated fixture voltage. The electrical characteristics of the Essentials fixture are indicated on the product label.
• Essentials fixtures are suitable for dry or damp locations.
• DO NOT install insulation within 6” of any part of Essentials fixture.
• DO NOT touch the lens of fixture (if applicable). If contact is made, clean glass with isopropyl alcohol. If NO lens,
DO NOT touch the reflector of fixture. If contact is made, clean reflector with isopropyl alcohol.
• Be cautious of any sharp edges. Wear proper safety gear (such as gloves and safety glasses) while handling.
MAINTENANCE
• Essentials fixtures should be dry dusted periodically as accumulation of debris can reduce life.
• The acrylic lens can be cleaned with common glass cleaner. DO NOT attempt to clean when fixture is turned on and illuminated.
TROUBLESHOOTING
WARNING: ALWAYS disconnect power from highbay fixture prior to servicing or troubleshooting. Turn circuit breaker/ panelboard disconnet off! DO NOT attempt to troubleshoot when power is still on.
Issue 1: Light fixture does not come on
• Step 1: Check breaker to ensure power (line voltage) is being delivered to highbay fixture.
• Step 2: Check electrical connections. Refer to wiring diagram in installation instructions to verify/confirm that fixture is wired correctly and power supplies are connected to light engine.
• Step 3: If steps 1 or 2 do not solve the issue, contact factory for replacement at 913-851-3000.
Issue 2: LED is out in module.
• Step 1: LED has failed. Fixture will continue to operate at reduced lumen output. Fixture replacement is optional.
For proper fixture operation - NO MORE than 20 LED can be out on a fixture.
Issue 3: Entire module (or 1/2 of multiple modules) is not lit.
• Step 1: Open the center channel wireway cover and locate power supply connected to failed module(s). `Apply line voltage to power supply and with voltmeter measure the output on the DC side of power supply. If power supply has proper voltage on DC side then, PCB board on module has most likely failed and fixture will have to be replaced. Please contact the factory at 913-851-3000. If power supply has NO voltage on DC side then, the power supply has failed contact the factory to get new power supply at 913-851-3000.
