TO INSTALL
REMOVAL OF EXISTING LIGHT
ENGINE
-
STEP 1:
Disconnect power to the host lighting fixture to be replaced. -
STEP 2:
Remove the Lens/Louver, Fluorescent Light Bulbs, Lamp Holders (if applicable), Lamp Holder Leads and Ballast Cover from existing lighting fixture. See Figure
- STEP 3:
Cut the power wires going into the input side of the ballast. The ballast may remain in place, un-less it is determined that it needs to be removed to provide extra clearance.
NOTE: If parts have to be removed from the host lighting fixture in order to complete the installation of this upgrade kit, then make sure that open holes are closed-off utilizing the existing host lighting fixture hardware (i.e. screws, covers, etc.)
INSTALLATION OF ZR-RK RETROFIT
-
STEP 1:
Install the assembly brackets to fit in the existing luminaire by using the (4) #8 1/2 screw. Make sure to secure the assembly bracket flat on the grid. See Figure 2. -
STEP 2:
Apply re-lamping label “This luminaire has been modified to operate LED panel. Do not attempt to install or operate fluorescent lamps in this luminaire” to the surface of the luminaire. You can login into Cree Lighting website to buy the specific model of LED troffer.

-
ZRRK24-XXL-8XX-10V5-UNV
-
STEP 3:
If there is a gap between the luminaire and t-grid, add optional trim brackets. Push up existing troffer housing and slide the trim brackets into place between existing luminaire and t-grid. See Figure 3. -
STEP 4:
Place the door assembly body onto the keyholes of the end brackets and slide the door assembly body horizontally to the end of the slots. See Figure 4 . -
STEP 5:
Attach (2) safety cables to existing troffer housing using washer head M4 screws provided in hardware bag. See Figure 5. -
STEP 6:
Wire luminaire per “Electrical Connections” section and tuck all leads into the back of the existing luminaire housing. Ensure that no leads are pinched. See Figure 5.
-
STEP 7:
Secure the door assembly by gently swinging the door up into the other side of the luminaire and then locking in place with the locking latches riveted on each end off the assembly door frame. See Figure 4.
CLEANING LENS
-
STEP 1:
Locate the end cap with the arrow marks on it, indicating that the end cap is removable. See Figure 6. -
STEP 2:
Squeeze the middle of the lens while grabbing the lens section next to the end cap and pull lens and end cap together downward gently until end cap just clears luminaire (about 3” to 4” from original position). See Figure 7. -
STEP 3:
Disengage the other end of the lens from the other end cap. Once lens is removed perform cleaning. See Figure 7.
-
STEP 4:
After cleaning is complete insert lens back into fixed end cap. Push the removable end cap upward into the housing and using a gentle rocking motion engage the end cap to retention clip. Check removable end cap for any visible gap between the end cap and end panel. If necessary push end cap against the end panel to eliminate gaps.
In 1’ X 4’ and 2’ X 4’ products, make sure lens is snapped under lens retention clips in middle of housing. See Figure 8.
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.
