TO INSTALL:
T- BAR CEILING MOUNTING
STEP 1:
Bring the FLEX troffer up into
the T-Bar grid.
STEP 2:
Locate the luminaire hooks and
bend them out 90 degrees for
installation. See Figure 1.
NOTE: The luminaire hooks ship
bent in and need to be bent out
for installation.
STEP 3:
Then bend the luminaire hooks
against the T-Bar to secure the
luminaire. See Figure 1.
SUSPENDED MOUNTING
STEP 1:
Attach customer supplied
cables to the (2) cable slots on
each side of the housing. See
Figure 2.
STEP 2:
Attach customer supplied
cables to mounting surface
using customer supplied
hardware. Ensuring that

STEP 2:
Release for 1 sec.
STEP 3:
Press/Hold RESET button for 0.5 sec. Light will turn off for a
few seconds then go to full bright and the Blue LED on the RF
Module should begin a 2 blink sequence. Figure 4.
INSTALLING TEST SWITCH
STEP 1:
Install test switch assembly into ceiling by drilling a 1” hole into
the ceiling.
STEP 2:
Unscrew the small trim ring and place test switch assembly
through the ceiling. See Figure 5.
STEP 3:
Secure the test switch assembly by screwing the small trim ring
removed in Step 5 back onto the test switch assembly. Tighten
the larger trim ring above the ceiling until it is snugged tight
against the ceiling. See
Figure 5.
CLEANING LENS
STEP 1:
Remove lens and end cap assembly by pulling straight
downward gently. See Figure 6.
STEP 3:
After cleaning is complete insert lens and end cap assembly
back into the luminaire housing. Check end caps for any visible
gap between the end cap and end panel. If necessary push end
cap against the end panel to eliminate gaps. Check lens for any
visible gap between the lens and luminaire.
TROUBLESHOOTING:
Out of the box, if the light does not turn on when power is
applied:
• Check Wiring with power off
• If wired correctly, check to see if Blue LED blinking on
the RF Module.
• If Blue LED is blinking, then perform a RESET
(See RESET RF MODULE section).

See Figure 3.
STEP 2:
Using customer supplied 90°C minimum rated wire
connectors, make the following electrical connections:
a. Connect the black luminaire lead to the
unswitched voltage supply lead.
b. Connect the white luminaire lead
to the neutral supply lead.
c. Connect ground wire lead to the supply ground lead.
STEP 3:
Locate the two red leads in the junction box and connect them.
STEP 4:
Push all leads into the junction box. Reattach junction box

EMERGENCY DRIVER CHECK
NOTE: For short-term testing of the
emergency function, the battery must be
charged for at least one hour. The emergency
driver must be charged for at least 24 hours
before conducting a long-term test.
STEP 1:
When AC power is applied, the charging
indicator light is illuminated, indicating the
battery is being charged. When power fails,
the emergency driver automatically switches
to emergency power, operating the LED array.
When AC power is restored, the emergency
driver returns to the charging mode.
STEP 2:
Although no routine maintenance is required
to keep the emergency driver functional, it
should be checked periodically to ensure
that it is working. The following schedule is
recommended:
• Visually inspect the charging indicator
light monthly. It should be illuminated.
• Test the emergency operation of
the fixture at 30-day intervals for a
minimum of 30 seconds. When the test
switch is depressed, the LED array
should operate.
• Conduct a 90-minute discharge test
once a year. The LED array should
operate for at least 90 minutes.
If the luminaire fails any of these checks,
consult service personnel.
REFER ANY SERVICING INDICATED BY
THESE CHECKS TO QUALIFIED PERSONNEL
EMERGENCY DRIVER AND AC DRIVER MUST
BE FED FROM THE SAME BRANCH CIRCUIT.
