4 Mounting
4.1 General instructions
The field housing of the VEGAMET 861 is equally suitable for outdoor
or indoor installation due to its degree of protection IP66/IP67 and
Type 4X. The standard version is designed for wall mounting. A
mounting adapter for pipe mounting is available as an option.
The instrument is suitable for standard and extended ambient condi-
tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used
indoors as well as outdoors.
Avoid direct sunlight or use the optionally available sun shade.
Make sure that the environmental and ambient conditions specified in
chapter "
Technical data
" are maintained.
Protect your instrument against moisture ingress through the following
measures:
•
Use the recommended connection cable (see chapter "
Connect-
ing to power supply
")
•
Tighten the cable gland
•
Mount the instrument in such a way that the cable glands point
downward
•
Loop the connection cable downward in front of the cable gland
This applies mainly to outdoor installations, in areas where high
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
The visible area of the front panel must be protected from knocks,
otherwise water can penetrate through breaking of the front foil. In this
case, protection against accidental contact can no longer be ensured.
Caution:
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.
The pressure compensation for the housing is realized via a breather
element.
Note:
Make sure that the pressure equalization element is always free of
buildup during operation. A high-pressure cleaner may not be used
for cleaning.
