4 Mounting

4.1 General instructions

Make sure that all parts of the instrument coming in direct contact

with the process, especially the sensor element, process seal and

processtting,aresuitablefortheexistingprocessconditions,such

as process pressure, process temperature as well as the chemical

properties of the medium.

nameplate.

Toprotectthediaphragm,theprocessttingiscoveredbyaprotec-

tive cap.

Remove the protective cap just before installation so that the dia-

phragm will not get damaged. It is recommended to keep the cap and

use it again later for storage or transport.

Select an installation position you can easily reach for mounting and

module. The housing can be rotated by 330° without the use of any

tools. You can also install the display and adjustment module in four

dierentpositions(eachdisplacedby90°).

You can give your instrument additional protection against moisture

penetration by leading the connection cable downward in front of the

cableentry.Rainandcondensationwatercanthusdraino.Thisap-

plies mainly to outdoor mounting as well as installation in areas where

high humidity is expected (e.g. through cleaning processes) or on

cooled or heated vessels.
