Only use original accessories.
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 ields.

6.2.1 Connection assembly

For instruments with ratiometric output signals, a shielded cable must be used. The
cable shield must be grounded, if the cable is longer than 30 m or leaves the building.
Use a cable with suitable characteristics for the particular operating conditions.
For cable variants, strain relief must be employed.
Cable with ventilation tubes must be vented to atmosphere.
The instrument must be earthed via the process connection!
Select a cable diameter that matches the cable gland of the plug. Make sure that the
cable gland of the mounted plug has a tight it and that the seals are present and
undamaged. Tighten the threaded connection and check that the seal is correctly
seated, in order to ensure a tight seal.
For cable outlets, make sure that no moisture enters at the cable end.
