Mounting
Proceed as follows to connect the communications module to functional ground via a
conductive mounting base:
1.
Drill 2 mounting holes with a distance of 155.6 mm.
2.
Screw the module together with the M4 fastening screws with a torque of 1.2 Nm.
NOTICE
Grounding with a conductive mounting base
If you fasten the communications module to a conductive, grounded base, the lower
fastening screw provides a conductive connection to the ground potential.
Ensure there is a low-impedance connection between the communications module and the
conductive base and between the conductive base and functional ground.
①
Grounded, metallic base
②
Unpainted thread or nut support
