T 6 Installation
6.9 Requirements to the temp erature sensor of the motor
In order to protect the motor against unacceptable overheating a motor temperature sensor can be connected
to the b maXX® BM3400 device. When exceeding an adjusted limit temperature the converter switches off
the motor. Requirements to the temperature sensor you will fi nd in «Appendix D - Temperature sensors of
the motor» on page 190.
NOTE
The motor temperature sensor is to be executed in such a way, that the Safe electrical separa-
tion is guaranteed. The motor temperature sensors in the Baumüller motors are accordant to
these requirements. If a motor of another manufacturer is connected the operator must assure,
that the motor temperature sensor of the other manufacturer complies with the function Safe
electrical separation.
The motor must be built in such a way, that the temperature sensor in the motor is sufficient to the criter ion
„Safe separation“ according to EN 61800-5-1.
The underlying rated voltage is 300 V or 600 V at operation on an IT-system.
