IMPORTANT SAFEGUARDS
When using electrical equipment, basic safety precautions should always be
followed including the following:
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
- DANGER – RISK OF SHOCK – DISCONNECT POWER BEFORE INSTALLATION
- WARNING – Risk of fire or electric shock. LED Upgrade Kit installation requires knowledge of luminaires electrical systems. If not qualified, do not attempt installation. Product must be installed in accordance with NEC or your local electrical code. If you are not familiar with these codes and requirements, contact a qualified electrician.
- WARNING – Risk of fire or electric shock. Luminaire wiring and electrical parts may be damaged when drilling for installation of the LED upgrade kit. Check for enclosed wiring and components.
- WARNING – Risk of fire or electric shock. Check the existing wiring for damage before installing upgrade kit. Do not install if existing wires are damaged.
- WARNING – To prevent wiring damage or abrasion, do not expose wires to the edge of sheet metal or any other sharp objects.
- WARNING – Risk of fire or electric shock. Install this kit only in the luminaires that have the construction features and dimensions shown in the photographs and/or drawings.
- The retrofit assembly is accepted as a component of a luminaire where the suitability of the combination shall be determined by ulu or authorities having jurisdiction
- Only the holes indicated in the photographs or drawings may be made or altered as a result of the kit installation. Do not leave any other holes open in a wiring enclosure or electrical component.
SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE
NOTES:
1. Upgrade Kit is for installation in a nominal 1×4 or 2×4 Listed dry or damp location fluorescent troffer, wrap or strip luminaire, with or without a diffuser. The luminaire shall have the following minimum dimensions:
- 2-15/16” deep pan
- 3“ wide minimum wiring compartment
- 43” minimum length to accommodate lightbars
- Only ONE kit is to be installed per luminaire
2. Consult your local authority regarding disposal or recycling of removed
ballast and lamp.

TO INSTALL
NOTE: The instructions below reflect the steps necessary for retrofit of
a typical fluorescent troffer luminaire. These steps are functionally
identical for retrofit of a typical wrap or strip luminaire.
STEP 1: Locate latches on the lens frame and release them allowing lens
frame to swing open. Carefully let lens frame hang. See Figure 1. STEP 2:
Remove existing linear fluorescent tubes and properly dispose of them. See
Figure 2. STEP 3:
To remove the wiring compartment, squeeze the sides in and pull down and set
aside. See Figure 3.
STEP 4:
Locate the existing ballast and remove the screw holding the ballast to the
housing. Properly dispose of the screw. See Figure 3. STEP 5:
To remove the ballast from housing, cut the leads from the ballast to the
socket housing on both ends of the luminaire and cap socket leads. See Figure
4 and 5.
NOTE: When cutting leads, leave the smallest amount of wire attached to
luminaire. STEP 6:
Cut the leads from the ballast to the input power ensuring to leave as much
length as possible for electrical connections. Remove ballast from housing and
properly dispose of. See Figure 6.
STEP 7:
Push exposed socket leads back into socket housing on each side of the
luminaire or cap any exposed accessible leads. See Figure 7. STEP 8:
Prepare input power by stripping input power leads 1/4”. See Figure 8. STEP
9:
Bring new driver into housing using mounting holes from old ballast and secure
it using supplied #8-32 screw. Ensure that the existing luminaire housing is
properly grounded to ensure proper driver grounding. See Figure 9.
NOTE: If housing has multiple locations for power supply, new driver can
be secured in any of these locations.
STEP 10:
Make electrical connection per “Electrical Connections” section on page 5.
NOTE: Ensure that the driver is properly grounded to luminaire using
supplied screw from Step 9.
STEP 11:
Bring wiring compartment previously removed in Step 3 into the housing.
Carefully tuck all leads and wire connectors into the wire compartment.
Reattach wire compartment by snapping into place over driver insuring no wires
are pinched. See Figure 10.
NOTE: Route the driver outgoing leads through the wiring compartment
allowing leads to be exposed through the end of the wiring compartment. See
Figure 10. STEP 12:
Snap (3) supplied mounting clips onto each LED lightbar. See Figure 11.
STEP 13:
Bring LED lightbar into housing and reposition clips on LED lightbar as
needed. For temporary placement of LED lightbar the clips have magnets located
on the bottom of the clip. Repeat this step for each LED lightbar supplied in
kit. STEP 14:
Once all LED lightbars are in desired position permanently secure them to
housing by inserting (2) supplied self tapping screws into each end of the LED
lightbar. See Figure 12.
NOTE: The middle bracket on the LED lightbar DOES NOT need to be secured.
STEP 15:
Connect the power supply leads connector, that is exposed at the end of the
wiring compartment with the LED lightbar connector. See Figure 13.
NOTE: For UR3 kits an extension cord needs to be applied to the lightbar
connector farthest from the wiring compartment and the power supply leads at
the end of the wiring compartment. See Figure 14.
NOTE: Place the revamp label, provided in the kit, on the lighting
compartment. Make sure that the label is visible.
TEP 16:
Close the lens door and secure the latches.
