To open the service hatch
Do as follows to open the service hatch:
1. With a Torx TX30 screw driver, loosen the 8 screws that keep the hatch in place.
2. Lower the service hatch and let it hang in the 2 strips
.
2.3.2 To ground the ADU
Ground the ADU at the mounting bolts. To ground the ADU do as follows:
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.
3. Tighten the bolt. Use stainless steel bolts and washers.
4. Seal the area suitably in order 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.
