Electrical Installation
Next, assemble the recommended ILSCO grounding lug to the aluminum frame using stainless
steel M3 or M5 screw and hardware as shown below. Note: there are two different size
grounding holes, the smaller of which is being phased out.
Further, buildup of hardware for mounting the grounding lug are the same—except for the M3
screw, an added flat washer is mounted directly under the M3 screw head. The star washer is
fitted directly under the grounding lug and makes electrical contact by penetrating the anodized
coating of the aluminum frame; the screw assembly is further fitted with a flat washer, then a
split lock washer and finally a nut to secure the entire assembly, as shown. Recommended
torque of M3 or M5 screw assembly is 0.8NM or 1.5 NM.
