Safety information

Note
Only connect one encoder system
Only one encoder system may be connected per Sensor Module.
NOTICE
Risk of equalization currents via the electronics ground
Make sure there is no electrical connection between the encoder system housing and the
signal lines and the sensor system electronics.
If this is not carefully observed, under certain circumstances the system will not be able to
reach the required interference immunity level (there is then a danger of equalization
currents flowing through the electronics ground).
