Connecting The Device - Siemens SITRANS P310 Kompaktbetriebsanleitung

NOTICE
Incorrect measured values with incorrect grounding
The device must not be grounded via the "+" connection. It may otherwise malfunction and be permanently damaged.
If necessary, ground the device using the "-" connection.

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 the device (Page 20)".
Note
Improvement of interference immunity
Lay signal cables separate from cables with voltages > 60 V.
•
Use cables with twisted wires.
•
Keep device and cables in distance to strong electromagnetic fields.
•
Use shielded cables to guarantee the full specification according to HART.
•
Refer to HART communication information in Chapter "Technical data (Page 34)".
