hardware (#10-32 hex head screw at 4 mm diameter, flat washers,
tooth lock washer and nut).
A #10 flat washer must be used between the screw head and the
grounding lug to prevent damage to the tin plating on the lug.
Insert a #10 flat washer between the grounding lug and the module
frame. A #10 tooth lock washer must be inserted between the nut
and the module frame to break the anodized layer of the frame.
This mechanical bond between the tooth lock washer and the frame
of the module will ensure a good electrical bonding path.
The #10-32 assembly attachment screw must be tightened between
20-25 inch-pound. A 10 AWG bare copper ground conductor must
be attached to the ground lug using the stainless-steel set screw
provided by the lug manufacturer. Tighten the set screw between
10-15 inch-pound to ensure a strong mechanical and electrical
bond.

assembly:
