Installation Instructions
HLF LED
2. With the yoke mounted securely and the weight of the luminaire supported so that it does not fall over, loosen
the two (2) 1/2" locking bolts just slightly enough to release clamping pressure to allow movement so the yoke
angle can be adjusted. For units with photocontrol receptacle, the fixture mounting angle must be restricted per
ANSI C136.10 and it is recommended to not install beyond 45° from horizontal.
3. When the desired angle is found, tighten one side of the yoke clamping bolt enough to secure housing, then
tighten both sides of the yoke back to approximately 35-40 ft-lbs (See Figure 3).
4. Make supply connections to the pre-installed 16-3 cord and energize the luminaire to verify operation and proper
illumination of area.
Driver Access
**THE FIXTURE SHOULD NOT BE ENERGIZED DURING ANY ELECTRICAL WORK**
The driver is pre-wired so access to the driver during installation is unnecessary. Open the fixture by loosening the four
or six hex key screws on the driver box cover and rotate the driver box cover away from housing to open. Ensure the
fixture is not energized and disconnect the electrical connectors to the affected driver. Remove the three slotted hex
screws holding the driver to the driver box cover. Remove the two slotted hex screws holding the driver to the bracket.
Attach new driver with two slotted hex screws torqued to 24 in-lbs. Reattach electrical connectors. Check gasket on
driver box for misalignment and correct as necessary. Rotate the driver box cover back to closed position and tighten
the six hex key screws (50 in.-lbs) EVENLY.
