Warning:
Caution – Risk of Shock
• This product must be installed in accordance with the applicable installation code by a person familiar with the construction and operation of
the product and the hazards involved.
• LEDs are ESD (Electro Static Discharge) sensitive devices that can be easily damaged if the proper ESD mitigating steps are not taken.
• LEDs are very sensitive to mechanical damage. Caution must be taken to avoid damage to the LEDs.
• Do not use power tools to fasten the boards into the fixture. Over-torqueing the LED board fasteners will damage the boards.
• Make sure all electrical power is turned off while installing the fixture.
• This luminaire must be adequately grounded for protection against shock hazards and to assure proper operation.
• Disconnect power before servicing.

Step 5: Place the canopy flush to ceiling tile and thread upper cable
retainer onto the 1/4 - 20 stud (Fig. 3).
A stand-alone fixture will require two suspension cables. The
5” diameter canopy will be used only at power feed locations.
Smaller 2” canopies are to be used at non-feed locations (Fig.
4). Power feed cord will pass through hole with plastic strain
relief bushing.
Note: For safety, always support the weight of the fixture. Do
not leave a fixture hanging by only one end while working.

Step 6: Hang the fixture from suspension cables by hooking into
each end of light fixture. Install 10 - 32 flange nuts from the
hardware kit onto threaded cable end and adjust up or down
as necessary until fixture is level (Fig. 5A). Fully adjustable
cables allow you to vary the length from 6” to 96” with a
stopping device that may be secured at any point along the
length of cable. One 10 - 32 flange nut from the hardware kit
secures the fixture.
NOTE: When hanging the junction box onto the T-bar
mounting bracket, tie the ceiling support wire for
this location directly to the T-bar.
