INSTALLATION

step 1: Disconnect power to the fixture.
Step 2 : For 2×2 or 2×4 luminaire installations, locate latches on the lens frame and release. Swing lens frame open and carefully allow the lens to hang open as shown in Figure 1.

NOTE: For vapor tights and lensed wraparound installations, remove the lens and set aside.
NOTE: For striplight and non-lensed wraparound installations go to Step 3.
Step 3 : Remove existing linear fluorescent tubes as shown in Figure 2. Dispose of tubes per local regulations.

Step 4: Remove the wiring compartment to access the existing ballast and set it aside. See Figure 3.

Step 5 : Cut the leads from the ballast to the socket housing on both ends of the fixture as shown in Figure 4.

NOTE: Cut the leads at the socket housing as short as possible. Push the leads back behind the lamp holder housing or cap any exposed leads. Lampholders may be removed but require removal of lamp holder leads.
Step 6: Cut the leads from the input power to ballast. See Figure 5.
NOTE: Cut leads at the ballast leaving as much length as possible to facilitate the installation of the driver. Strip wires as necessary.

Step 7: Remove ballast by unscrewing it from the fixture and dispose of it properly per local regulations. See Figure 6.
Step 8: Locate a flat area on the fixture within the wiring compartment to mount the driver. The driver must set flush with the fixture for proper thermal management. Install the driver where possible using existing crow’s feet or mounting holes, and the provided two drill point screws with serrated heads. Ensure the driver is properly grounded. See Figure 7.

NOTE: For stoplight mounting. it is recommended to minimize exposed blue and red light bar leads to 3.
Step 9: Red finer from double-sided foam tape strips at opposite comers of the light bar. Position the light bar approximately at the centerline of existing lamp sockets and center between the sockets as shown n Figure 8. Apply pressure to temporarily affix the light bar.
NOTE: Remove any support brackets for U Bend fluorescent lamps. These are typical in some 25(2′ luminaires. For stoplight fixtures. position the lamps on the wiring compartment cover.
For circular surface or pendant mount luminaires. be careful to position the light bars so that the branch circuit wiring insulation will not be abraided or cut.
Step 10: Once positioned secure light bar to the fixture with the (6) provided self-tapping screws as shown in Figure 9. Repeat for additional light bars.

CAUTION: Foam tape is temporary for ease of installation. Do not complete retrofit installation without securing screws (3 per lamp).
Step 11: Recommended mounting pattern. See Figure 10.

Step 12: Connect red leads from both light bars to the loose red lead wire with the supplied orange 3-position connector by pushing into the open slot. Repeat for blue leads. See Figure 11.

Step 13: Connect red and blue lead wires to the comet diver contacts as indicated on the driver label. See Figure 12.

NOTE: Optional 0-10V Analog Dimming Interface

• Use Violet (+) and Gray (-) for connection to 0-10VDC.
• Capping Violet and Gray separately provides 100% light output.
• Wiring Violet and Gray together provides minimum light output.
• The dimming control connections on the LED driver are for Class 2 wiring methods only. Separate the dimming control field wiring from the branch circuit field wiring in the wiring compartment in accordance with the National Electrical Code.

Step 14 : Prepare input power leads by stripping 1/4”. Connect power lead wires to the correct driver contacts as indicated on the driver label. See
NOTE: If the existing black and white lead wires are too short to reach the new driver position, an extension can be created using the provided black and white leads and red two-position connector.

Step15: Wiring Schematics

Step 16: Replace wiring compartment cover. Dress light bar leads under the cover. Take care not to pinch red and blue leads between the cover and fixture.
Step 17: Place relamp label at a visible location in the fixture. Close or replace the lens and secure latches or other fastening means.
