Only use original accessories. For accessories see data sheet PE 81.61.
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.
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 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 a tight seal.
For cable outlets, make sure that no moisture enters at the cable end.
