Safety information

NOTICE
Only one measuring system can be connected to each Sensor Module.
Note
There must be no electrical connection between the encoder housing and the motor (this
requirement is fulfilled for most encoder systems).
If this is not carefully observed, under certain circumstances the system will not be able to
reach the required noise immunity (there is then a danger of equalization currents flowing
through the electronic ground).
