If external Teach-In option is not used, the Teach-In wire must be attached to GND.
10 Grounding concept
For maximum EMC protection and reliable application, use a shielded cable. Also, the sensor has to be
grounded.
We recommend the grounding concept as shown in the picture. Ground the sensor with a toothed washer
between the screw head and the sensor.

OADM
If you prefer another grounding concept please contact your Baumer electric sales staff.
11 Service notes
The OADM requires no maintenance apart from keeping the front windows clean. Dust or fingerprints can
impair the sensor function. It is normally sufficient to wipe the windows dry with a clean (!), soft cloth. Alcohol
or soapy water may be used for heavy soiling.
