The process connections of the available adapters and/or measuring chambers are to be
properly sealed and connected to the measuring point.
6.1.3 Installing the instrument
■
When screwing the instrument in, the force required to do this must not be applied through
the case, but only through the spanner flats provided for this purpose and using a suitable
tool. The torque should maximally be 60 Nm when screwing it in.
■
When screwing in, do not cross the threads.
6.2 Electrical mounting
WARNING!
The instrument shield does not act as a protec-
tive conductor for protection of personnel,
rather as a functional ground in order to shield
the instrument from electromagnetic fields.
6.2.1 Connection assembly
■
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 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 the ingress protection.
■
Make sure that no moisture enters at the cable end.
