Avoid twisted and/or tensioned lines. For this reason, always route connection lines correctly. Route con-
nection lines separately from the lines of the power electronics.
The area around the thermometer must also be kept clean because aggressive media in particular could
chemically attack the thermometer, potentially damaging the construction. If the thermometer needs to
be used in aggressive media or contact with such media cannot be ruled out, it must be ensured that the
probe features are tailored to the respective installation situation.
NOTE!
Cable passages must match the respective cable diameter. If the cables have not been properly routed,
it will not be possible to ensure a reliable seal or compliance with the protection types.
8.2.2 Screw-in thermometer
NOTE!
Do not exceed the specified maximum torques!
If a maximum torque has not been specified, it must be determined empirically.
The tightening torques from the table below apply as a general guideline. The values specified here ap-
ply to dry screw connections (steel to steel).
Responsibility for choosing the correct tightening torques always lies with the user, because the torques
essentially depend on the respective installation situation and the specific thermometer.
