4 Mounting
4.1 General instructions
In the standard version, the PLICSMOBILE T81 is designed for
wall mounting. Mounting adapters for carrier rail mounting (top hat
rail 35 x 7.5 according to DIN EN 50022/60715) as well as for tube
mounting are optionally available.
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.
Make sure that the environmental and ambient conditions specified in
chapter "
Technical data
" are maintained.
Check before mounting if a sufficient network coverage (signal
strength) of the mobile network provider is available at the planned
location. This can be simply tested by means of a mobile phone.
Keep in mind that the SIM cards in the PLICSMOBILE T81 and in the
mobile phone are from the same mobile phone provider or work in
the same mobile phone network. The PLICSMOBILE T81 supports
the mobile phone standards 2G (GSM) and 3G (UMTS). The mobile
phone standard 4G (LTE) however is not supported. Therefore for this
test of the network coverage, the 4G standard in the mobile phone
should be temporarily switched off.
If the radio reception is too weak, you should search for a better posi-
tion. In closed rooms this would be, for example, close to a window
or at least closer to an outer wall. In addition, an antenna extension
with magnetic base is available which can be placed up to 2.9 m away
from the instrument.
Caution:
During operation, a distance of at least 20 cm should be kept between
the antenna and persons working nearby. Operation of the instrument
with smaller distances is not recommended.
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
•
When mounting horizontally, turn the housing so that the cable
gland points 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.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Make sure that the degree of contamination specified in chapter
"
Technical data
" meets the existing ambient conditions.
