4.2.2 Installing the Evaluation Unit
Note the following points when installing the evaluation unit:

Position the evaluation unit depending on the length of the
HF cable in the vicinity of the microwave probe.

The evaluation unit has to be protected against vibrations.
In some cases, it is advisable to set up the evaluation unit
on a stand separated from the pipeline system.

For instrument installation you should foresee a cutoff de-
vice to allow easy and quick disconnection of the device
from the power supply.

Provide an automatic separating device (line circuit breaker)
that disconnects the unit from power within 0.03 seconds in
case of failure. The separating device must be matched to
the cable cross-section of the supply line, but at least it
must be designed for 1 A continuous current.

When installing the evaluation unit on a crystallizer, use a
distance rail to minimize the thermal radiation and conduc-
tion. See Figure 4-3:

For outdoor applications, the evaluation unit must be pro-
tected from direct sunlight and rain, for example by a suita-
ble shelter.
