Electrical connection
NOTICE
The control is designed as a SELV (Safe Extra Low Voltage) circuit. In this way, the
(internal) supply fulfils the requirements for safe separation of the supply. GND is
not connected to PE.
NOTICE
The pump can be switched on and off without intervention from the operator. This
can be done, for example, using the control function, by external BMS connection or
also by the function EXT. Off.
If pumps are delivered with a differential pressure sensor fitted, it is connected to ana-
logue input Al 1 at the factory.
If the differential pressure sensor is connected on-site, carry out the cable assignment
as follows:

NOTICE
For a twin-head pump or Y-pipe installation, connect the differential pressure
sensor to the main pump! The measuring points of the differential pressure sensor
must be on the suction and discharge side of the double-pump system in the com-
mon collector pipe. See chapter "Twin-head pump installation/Y-pipe installation".
Wilo Net is a Wilo system bus used for establishing communication between Wilo
products:
ƒ
Two single pumps as a twin-head pump in the Y-piece or one twin-head pump in a
twin-head pump housing
ƒ
Several pumps used with Multi-Flow Adaptation control mode
