5.2 Electrical mounting

WARNING!
The instrument shield does not act as a protective conductor for protection of personnel, rather as a
functional ground in order to shield the instrument from electromagnetic fields.

5.2.1 Connection assembly (model GD-20-D)

Use a cable consisting of shielded twisted pair data lines with suitable characteristics for the particular operating
■
conditions.
Select a cable diameter that matches the cable bushing of the connector. Make sure that the cable gland of the
■
mounted plug has a tight fit and that the seals are present and undamaged. Tighten the threaded connection and
check that the seal is correctly seated, in order to ensure the ingress protection.
Make sure that no moisture enters at the cable end.
