SECTION 1: INSTALLATION INSTRUCTIONS
1.1 Disconnect all power to the luminaire being worked on and remove the old luminaire from the
ceiling Inspect the ceiling for any damage. Make sure the ceiling is rated for 4X the load.
1.2 Remove the new fixture from the box and check for any damages. Handle new fixture with care.
If damaged do not use; call your local rep for replacements.
1.3 Decide on a hanging or mounting method that will work for your application. If unsure of how to
hang fixture, contact your local rep or manufacturer. Make sure the new fixture is securely
mounted to the ceiling structure.
• If hanging fixture by optional mounting bracket, use the provided carriage bolt to secure the
bracket to the fixture. Do not over tighten the carriage bolt. This will deform the hanging bracket.
Make sure the bracket grip flange snaps into the groove on the fixture channel. SEE FIGURE 1.
• If hanging by chain, optional trapeze hangers can be purchased. The trapeze hanger clips into
the pre-punched loop on the luminaire end cover. Remember to crimp the trapeze hanger to
create a closed loop when done. Due to manufacturing tolerances, the loops on the end cover
might be a little lower on some units. Use a small tool to slightly increase the loop diameter if
needed in order for the trapeze wire diameter width to fit.
• If hanging by Gripple System, optional Gripple cables and hardware can be purchased. Insert the
hook connector into the 5/16” diameter holes on the back of the fixture.
• If stem mounting, use only approved stem hardware rated for 4X the load.

1.8 DOOR VERSION (for extra security): - Install the extra clip to the door using the provided
½” self-threading machine screw and plastic retaining washer as shown in FIGURE 2. This
should be done on the latch door side. The screw should engage the pre-punched nail
hole on the side of the fixture rail. This step is required on all high bay with door options.
SECTION 2: FIELD INSTALLED DOOR INSTRUCTIONS
2.1 Install the clips onto the door hinge rail rectangle slots (3 per side for the 2x4 door and 2 per side
for the 2x2 door). Install the door onto the fixture using the provided ½” self-threading screws.
The door should swing smoothly.
2.2 Install the nylon spacer onto the ½” self-threading machine screw. SEE FIGURE 2.
2.3 Install the screws into the pre-punched nail hole on the fixture (2 per fixture). Do not over tighten
the screws; this will deform the nylon spacer. SEE FIGURE 2.
2.4 Rotate the door to close position and rotate the latches to lock the door into position. NOTE:
make sure the latch fully engages the nylon spacer.
2.5 Install the extra clip on the latch side, center on door using the provided ½” self-threading machine
screw. The screw should engage the pre punched nail hole on the side of the fixture rail.
SEE FIGURE 2.
SECTION 3: FIELD INSTALLED WIRE GUARD INSTRUCTIONS
3.1 Install the clips onto the wire guard (make sure clips are oriented correctly). Test fit the first wire
guard onto the fixture to make sure the clips are installed in the correct cell. The clips should line
up with the pre-punched nail holes on the side of the fixture. Make sure the wire guard is centered
on the fixture. SEE FIGURE 3.
3.2 Mount the wire guard to the fixture using the provided ½” self-threading screws. The screws
should line up to the pre punched nail holes on the side of the fixture. DO NOT OVER TIGHTEN
SCREWS. SEE FIGURE 3.

SECTION 4: SENSOR EQUIPPED HIGH BAY
4.1 Remove the protective covering on the sensor unit. Remove the protective wire bushing on the
end cover. This is used to protect sensor wiring during shipping.

ballast(s).
5.3 Follow wiring diagram on the ballast. Use only UL recognized components and wires rated 90C or greater.
5.4 To replace the lamp holders, remove the lamp holder brackets. Install the new lamp holders into the existing location.
Follow lamp holders wiring diagram on ballast. If unsure please contact factory.
5.5 Reinstall the lamp holder brackets by sliding them into the pre formed clips on the end covers.
5.6 Reinstall the reflectors using the old hardware. Use gloves when handling reflectors, edges are sharp. IMPORTANT
– Do not use pliers to reinstall the middle reflectors camlocks. Use special fastener tool or hands. Pliers crush the
fasteners causing the camlocks to be loose.
