9.3 The GSM module location

The GSM module can be located easily inside the cubicle mounted on a DIN-RAIL. This solution simplifies the
housing of the module and the wiring (short wires). This arrangement suits a solution of an antenna cable
connected at the housing of the GSM module with a SMA male connector.
The cable will be allowed to come out the cubicle via a PG sleeve.
Please refer to Air Contact Installation Manual.

9.4 The antenna placement

This device has to be placed outside the compressor cubicle. This leads to the need of a cable
to connect the antenna to module. The connection distance between antenna and module can
also vary from case by case, and to be installed at the customer site. The chosen standard
solution is an external antenna with magnetic base, prewired with 5 m cable and connected to
the Air Contact via a male SMA right angle type connector.
