2.4.2 To ground the ADU
The ADU must be grounded using one of the mounting bolts. To ground the ADU do as
follows:
1. Clean the metal underneath the head of
at least
one bolt of insulating protective
coating and use a serrated washer to obtain a good ground connection. For optimum
grounding connect the ground wire to the bolt marked in the figure below.
2. Tighten the bolt. Use stainless steel bolts and washers.
Tightening torque value: 30 Nm.
3. Seal the area suitably to avoid corrosion of the grounding point (recommended).
If the ADU cannot or should not be electrically connected directly to the mounting surface,
use a separate grounding cable to make the connection between the ADU and the common
ground to which the BDU is also connected.
