pressure monitor are provided. Only connect intrinsically safe simple operating means with suitable connection
data to these terminals in accordance with the Table below. Otherwise the explosion protection of the connected
sensors is not ensured. Only connect intrinsically safe devices with appropriate connection data to these termi‐
nals.
