When using combustible media:
Connect the stroke sensor to a suitable monitoring device according
to the details in the chapter "Technical Data" - also observe their
technical data!
The monitor / power supply installed by the customer must be able
to evaluate the current variations of the Namur sensor for indicating
a diaphragm rupture!
Install the heating cartridge according to its documentation. It must
only be connected to the supplied power supply or the protective
temperature limiter (for ATEX)!
Electrically connect the entire supplied installation according to the
earthing plan of the pump documentation cleanly and permanently to an
electrically clean earthing point, e.g. with an earthing bar of your system.
Either solder or screw the wires firmly in place.
WARNING!
The pressure switch must not be reprogrammed without the
written authorisation of ProMinent GmbH, Heidelberg.
