WARNING!
Physical injuries and damage to property and the
EN
environment caused by media escaping under high
pressure
With the pressurisation of the instrument, as a result of
poor sealing of the process connection, media under high
pressure can escape.
Due to the high energy of the media that can escape in
the event of a failure, the possibility of physical injuries and
damage to property exists.

6.1 Mechanical connection

In accordance with the general technical regulations for pressure gauges
(e.g. EN 837-2 "Selection and installation recommendations for pressure
gauges").
Instruments must be grounded via the process connection.
This is why electrically conductive sealing should be used at the process
connection. Alternatively, take other measures for grounding. Grounding
measures applied from the factory (e.g. welding points or fuse plates)
must therefore be used to integrate the instruments into the equipoten-
tial bonding and must never be removed. Make sure that, following any
dismounting (e.g. instrument replacement), the grounding measures are
reinstalled.
Installation with open-
ended spanner

The sealing of the process connection must be carried out
expertly and checked for leak tightness.
