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 Technical
data (Page 199).
Note
Improvement of interference immunity
● Lay signal cables separate from cables with voltages > 60 V.
●
Use cables with twisted wires.
● Keep device and cables at a distance from strong electromagnetic fields.
● Take account of the conditions for communication specified in the Technical data
(Page 199).
● Use shielded cables to guarantee the full specification according to HART/PA/FF/Modbus/
EIA-485/Profibus DP.
