NOTICE
Ambient temperature too high
Damage to cable sheath.
● At an ambient temperature ≥ 60 °C (140 °F), use heat-resistant cables suitable for an
ambient temperature at least 20 °C (36 °F) higher.
NOTICE
Condensation in the device
Damage to device through formation of condensation if the temperature difference between
transportation or storage and the mounting location exceeds 20 °C (36 °F).
● Before taking the device into operation, let the device adapt for several hours in the new
environment.
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 Connecting (Page 57).
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 195).
● Use shielded cables to guarantee the full specification according to HART/PA/FF/Modbus/
EIA-485/Profibus DP.
