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
processfitting,aresuitablefortheexistingprocessconditions,such
as process pressure, process temperature as well as the chemical
properties of the medium.
Youcanfindthespecificationsinchapter"Technical data" and on the
nameplate.
The instrument is suitable for standard and extended ambient condi-
tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1.
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. For this reason, the housing can be turned without any
toolsby270°.Rainandcondensationwatercanthusdrainoff.This
applies 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.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
