Note
Electromagnetic compatibility (EMC)
You can use this device in industrial environments, households and small businesses.
For metal housings there is an increased electromagnetic compatibility compared to high-frequency radiation. This
protection can be increased by grounding the housing, see Chapter "Connecting (Page 31)".
Note
Improvement of interference immunity
● Lay signal cables separately to cables with voltages > 60 V.
● Use cable with twisted wires.
● Keep the device and the cables at a distance from strong electromagnetic fields.
