STEP 1.
Remove the bottom-left pre-installed M6 x 16mm Hex Cap Screw.
STEP 2.
Install bracket on XR luminaire as shown using supplied M6 x 20mm Hex
Cap Screw. Torque M6 x 20mm Hex Cap Screw to 40 in-lbs (4.5 Nm). It is
strongly recommended that a medium or high strength thread-locker be
used when installing the bracket. For units using surface or suspension
mounting, install safety kit hardware on top of the surface mount or
suspension mount brackets in the same location as shown.
STEP 3.
Attach stainless steel chain to safety kit bracket using stainless steel oval
shaped threaded connecting link.
STEP 4.
Attach loose end of chain. Secondary safety mounting point must be
suitable for supporting a minimum of 120lbs:
- Attach loose end of stainless steel chain to xed eye-bolt (not
