3.1 General instructions for use of the instrument
Protect your instrument against moisture ingress through the following
measures:
•
Use a suitable connection cable (see chapter "
Connecting to
power supply
")
•
Tighten the cable gland or plug connector
•
Lead the connection cable downward in front of the cable entry or
plug connector
This applies mainly to outdoor installations, in areas where high
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Note:
Make sure that during installation or maintenance no moisture or dirt
can get inside the instrument.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
