MAINTENANCE MANUAL
• To avoid the risk of fire, explosion, or electric shock, this product must be installed in accordance with the applicable
installaon code by a person familiar with the construcon and operaon of the product and the hazards involved.
• Be certain electrical power is OFF before and during installaon and maintenance. It is recommended that prior to
installaon the main breaker controlling the desired locaon for the fixture be turned off.
• The luminaire must be connected to a wiring system with an equipment-grounding conductor.
• Ensure the supply voltage is the same as the rated luminaire voltage.
• Inspect each fixture for any signs of damage before beginning installaon; do NOT install any fixture that is damaged.
• All wiring should be performed by a qualified technician and according to the appropriate local electrical code. Wear
gloves when disassembling fixture.
• Locate a posion to install the light fixture. The selected locaon must not hinder venlaon to the fixture unless
product specificaons indicate otherwise.
WARNING
General Wiring Diagram
The fixture comes pre-assembled from the factory. Depending on customer needs, the lighng fixture will either come with
or without an installed power cord.
Pre-installed power cord
• Make the appropriate wire connecons between the cord and the power source. All wire connecons should be
completed using approved/appropriate wire connecons according to all applicable electrical codes.
• Wires must not be exposed or frayed. Inspect wires for any signs of damage.
NO pre-installed power cord
If there is no pre-installed power cord with the fixture, access to the internal components will be needed to make the
appropriate wire connecons.
1. Remove the lens by locang and releasing the latches holding the lens to the housing. Support the lens while releasing
the latches to avoid dropping the lens.
2. The LED tray is held in place using clips down the center of the tray or in an alternate design, with four Quarter-Turn
fasteners. Support the tray while releasing it from the housing and as the LED tray swings down, gently hang it from the
fixture as it is supported by plasc Tethers. The 8models will ulize two separate 4long LED Trays.
3. Run the external power line wires through the end of the housing and make the appropriate wire connecons. All wire
connecons should be completed using appropriate wire connecons and according to local electrical code.
4. Use appropriate parts/accessories to ensure the housing wire port is sealed to prevent water/dust intrusion.
5. Inspect the closed cell polyurethane gasket for any gaps or damage.
6. Reaach the LED tray and lens.

The fixture will be supplied with the FMB Slide plate already mounted. Mount the FMB Box to the building pendant
conduit in preparaon to slide the fixture in place. Slide the fixture into the FMB Box and secure in place with one of
the supplied #8 screws. Perform the appropriate wiring connecons and then aach the FMB Door to the assembly
as shown using a #8 screw. For 8fixtures, two FMB boxes will be supplied and must be spaced accurately as shown
below.
FMB Kit Installaঞon
Install the two brackets into the desired surface using appropriate hardware (supplied by others). Aach the standard
surface-mount brackets to the 45DEG angle brackets as shown below using the supplied hardware. Aach the fixture
to the brackets using the same method shown in the Surface-Mount instrucon above. Dimensions are approximate.

INSTALLATION &
MAINTENANCE MANUAL
If the fixture fails to operate once installaon has been completed:
• Ensure there is power to the fixture.
• Ensure the fixture is properly wired and grounded.
• Check to see if there are any loose wires inside the light fixture.
• Ensure the line voltage at the fixture is correct.
If none of these steps resolve the issue, contact your ILP representave for further assistance.
Depending on the applicaon of the fixture, maintenance schedules will vary and should be developed by the customer
following periodic observaon once fixtures are in operaon. At a minimum, the exterior surfaces should be wiped
down as part of regular maintenance.
Due to the IP rangs of the fixture, there should be no accumulaon of dust or moisture within the fixture. Therefore,
the fixture should only require dusng/wipe-down of the exterior surfaces as part of the regular maintenance.
However, if a more thorough cleaning is required or desired, the lens may be removed and washed according to the
following steps:
Lens Cleaning
1. Ensure power is turned offor disconnected before proceeding with maintenance. Once fixture is powered off,
ensure the fixture is given enough me to cool.
2. Idenfy the latches securing the lens to the housing. While supporng the lens in place, release all the latches.
Carefully lower lens from housing.
3. Clean the lens using warm water, then wipe down to dry. Use non-abrasive materials to prevent damage.
4. Inspect the closed cell polyurethane gasket around the perimeter of the housing before reinstalling the lens. The
gasket should have no gaps and should be capable of creang a ght seal.
5. Reinstall lens onto fixture housing.
