C.6.3 Isolation of the ADU from the mounting base
In cases where the ADU is to be isolated from the mounting base, do as follows:
1. Use shoulder bushings and washers (accessories) as illustrated below. Note that the
isolation must be implemented on all four mounting bolts (including the bolt securing
the ground cable).
2. Connect the ground cable at one of the mounting/grounding bolts on the ADU as
illustrated below.
3. Seal the joint with protective coating to avoid corrosion.
