5.3 Connection without the use of a measuring line
The smallest bending radius of the measuring line should not be less than 6 mm. Bending
or interruption of the measuring line lead to failure of the instrument.

If there are shocks or vibrations at the installation site of the probe, form several freely
swinging loops between the last fixing point and the probe. Any excess length must also be
coiled, since cutting the measuring line would render the instrument unserviceable.
Avoid welding or soldering and permanent fastening of the measuring line as this could
seriously damage the measuring line and impair the operation of the instrument.
The measuring line should not be installed close to cold or heat sources.
5.4 Case mounting
The case ingress protection is indicated on the product label and must be observed during
installation.
If possible, mount the indicator case at a shock- and vibration-free location, but observe at
least the following limit values:
Frequency range < 150 Hz
Acceleration < 0.7 g (7 m/s
)

A flexible connection line between the measuring point and thermometer can be used to
isolate the installation from the measuring point.
To ensure the best measurement accuracy possible, the ambient temperature on the
indicator case should be between 0 ... 40 °C. Higher or lower ambient temperatures can
cause indication errors.
