WARNING
Unsuitable cables and/or cable glands
Danger of explosion in hazardous areas.
● Only use suitable cables and cable glands complying with the requirements specified in Chapter "Technical data
(Page 35)".
● Tighten the cable glands in accordance with the torques specified in Chapter "Technical data (Page 36)".
● When replacing cable glands use only cable glands of the same type.
● After installation check that the cables are seated firmly.
WARNING
Incorrect selection of type of protection
Danger of explosion in areas subject to explosion hazard.
This device is approved for several types of protection.
1. Decide in favor of one type of protection.
2. Connect the device in accordance with the selected type of protection.
3. In order to avoid incorrect use at a later point, make the types of protection that are not used permanently
unrecognizable on the nameplate.
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 (68°F).
● Before taking the device into operation let the device adapt for several hours in the new environment.
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 (68 °F) higher.
Two-wire mode
NOTICE
Connection of voltage source to current input
Device damage if a voltage source is connected to the current input I
● Never connect the current input I
● Always use a voltage source with a maximum output current of I = 20 mA.
Note
Improvement of interference immunity
● Lay signal cables separate from cables with voltages > 60 V.
● Use cables with twisted wires.
● Avoid getting too close to large electrical process cells.
● Use shielded cables to guarantee the full specification according to HART.
● Take account of the conditions specified in the technical data for HART communication.
