Explosion protection
Installation point
● Flameproof enclosure "d"
● Intrinsic safety "ia"
● Types of protection"ic", "nL", "nA nL"
● Dust, protection by enclosure "tD"
Permissible ambient temperature
● For operation with or without HART
● For operation with PROFIBUS PA or
with FOUNDATION Fieldbus
At ≤ -10 °C (+14 °F), the display refresh rate of the display is limited. For basic devices with explosion protection: When
1)
using Iy module, only T4 is permissible.
Natural gas as actuator medium
See detailed operating instructions for technical data for natural gas as actuator medium.
