TO INSTALL:
T BAR CEILING MOUNTING
STEP 1:
Bring the ZR-MT 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:
Disconnect power to circuit by
turning circuit breaker OFF before
installation.
STEP 2:
Attach customer supplied cables
to the (2) cable slots on each side
of the housing. See Figure 2 and 3.
STEP 3:
Attach customer supplied cables
to mounting surface using
customer supplied hardware.
Ensuring that mounting surface
can support the luminaire.
STEP 4:
Make wiring connections per the
Electrical Connection section.
STEP 5:
Switch the circuit BREAKER on.
STEP 6:
Make sure the WIM blue LED has
a double blink pattern. If not,
please proceed to Troubleshooting
section. Otherwise, you can
proceed to commission the zone
controller. Please refer to the
Smartcast® document ion for
details. See Figure 4 on the next
page.

RESET
STEP 1:
Actuate RESET button through the access hole. Press
and hold Test/Reset button until the LED flashes fast
(approximately 5 seconds). See Figure 4.
STEP 2:
Release the Test/Reset button for 1 second (Fast flashing
continues). Press and hold Test/Reset for 1 second until fast
flashing stops. If the blue LED does not respond with the
two-blink sequence, please repeat the RESET procedure..
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 endcap by pulling down gently on one end
near endcap. See Figure 6.
STEP 2:
Before installing lens, ensure that one endcap is already
installed.
STEP 3:
After cleaning is complete, place loose endcap back onto
lens and angle lens into fixed endcap. After getting lens
seated into fixed endcap, rotate upwards to engage loose
endcap into position. See Figure 6. Lens may need to be
squeezed together to help guide into pan.
STEP 4:
Confirm there are no visible gaps along entire length of lens
and around endcaps. If necessary, push endcaps against
end panel or lens against luminaire to eliminate gaps
NOTE: If fixed endcap comes loose during removal, push
upwards while using end panel as a stop to engage clips
See Figure 7.

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 has a double blink
pattern. If not, please proceed to RESET procedure.
• If Blue LED is blinking, then perform a RESET (See RESET
section).
• If Blue LED is on solid or off, call Cree Lighting Customer
Service.
• If you have done a RESET, and the light is still off, call Cree
Customer Service..
If light is unresponsive, use Cree Lighting Configuration Tool to verify
configuration.
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.
