6. Commissioning, operation

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 sealings should be used at the process
connection. Alternatively, take other measures for grounding. When screwing the
instruments in, the force required for sealing must not be applied through the
case, but only through the spanner flats provided for this purpose, and using a
suitable tool.
