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 mounting surface can support the
luminaire.
0 - 10V DIMMING OPTION
STEP 1:
Remove the cover of the junction box and bring in appropriate power
supply to the junction box using one of the knock-outs. See Figure 3.
STEP 2:
Remove the cover of the dimming junction box and bring dimming
conduit into dimming wire compartment using the knock-out. See
Figure 3.
STEP 3:
Wire luminaire per “Electrical Connections” section and push all leads
into the junction box. Reattach junction box cover that was removed in
Step 1 , make sure no wires are pinched.
STEP 4:
Install test switch assembly into ceiling by drilling a 1” hole into the
ceiling.
STEP 5:
Unscrew the small trim ring and place test switch assembly through the
ceiling. See Figure 4.
STEP 6:
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 4 on the next page.

CLEANING LENS
STEP 1:
Remove lens and end cap assembly by pulling
straight downward gently. See Figure 5.
STEP 2:
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.
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.

ELECTRICAL CONNECTIONS
NOTE: The emergency driver must be fed from
the same branch as the AC Driver.
STEP 1:
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/red luminaire lead to
the switched supply switched.
c. Connect white luminaire lead to the neutral supply lead.
d. Connect ground bare or green/yellow wire
lead to the supply ground lead.
e. If 0/1-10V Dimming is used, connect the violet lead
to the supply positive dimming lead. If dimming is
not being used ensure to cap off the violet lead.
f. If 0/1-10V Dimming is used, connect the gray lead
to the supply negative dimming lead. If dimming is
not being used ensure to cap off the gray lead.
g. Secure incoming dimming leads to the existing strain
relief, to prevent contact with primary wiring.
STEP 2:
Locate the two red leads in the junction box and connect them using
customer supplied connector.
