In the version with intrinsically safe outputs, an additional IP 40 cover is used for
the power supply terminals in the wiring compartment. Do not open the IP 40 cover
while circuits are alive! In the combination "EEx de wiring compartment" and
"intrinsically safe outputs", connection and disconnection of intrinsically safe wiring
(terminals 22/23 and 26/27), and measurements with certified measuring devices
is also permitted during operation.
