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.
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. If the radio reception is too weak, you
should search for a better position. In closed rooms this would be, for
example, close to a window or at least closer to an outer wall.
Note:
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.
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. Rain and condensation water can thus drain off. 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.
4.2 Installation procedure
