5.1.2 Installation using an adapter and measuring chambers

EN
The process connections of the available adapters and/or measuring
chambers are to be properly sealed and connected to the measuring
location.
5.1.3 Installing the instrument
When screwing in the instrument, 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.

5.2 Electrical mounting

5.2.1 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 bushing of the connec-
■
tor. Make sure that the cable gland of the mounted connector 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.

CAUTION!
If the model GDHT-20 is delivered with an adapter or measur-
ing chamber, it is completely mounted and tested for leak
tightness ex-works. Dismounting compromises the leak
tightness of the measuring assembly and renders it unser-
viceable!
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.
