Pumps for this system can each have a cable with 3, 6 or 9 wires. 3-wire cables
are for the 230 V version, the pump(s) of which can be connected by Phoenix contact
plugs on the outside of the underside of the control unit. For this reason, no further
information about this version is provided in this section. For 9-wire cables, double
assignment of the phases in the wastewater pump (
