You must fulfill the following conditions before supplying auxiliary power to the positioner in
potentially hazardous areas:
The installed electronic unit has been approved.
The enclosure of the positioner is closed.

certified cable inlets or sealing plugs.
You must install an ignition trap if you use a "conduit piping system". The maximum
