Installation and operating instructions Wilo-Stratos GIGA2.0-I, Wilo-Stratos GIGA2.0-D 173
NOTICE
The terminals of the analogue inputs, digital inputs and Wilo Net meet the “safe
isolation” requirement (according to EN 61800-5-1) to the mains terminals, the ter-
minals SBM and SSM (and vice versa).
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 EXT function. Off.
7.4 Differential pressure sensor con-
nection
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:
Cable Colour Terminal Function
1 Brown +24 V +24 V
2 Black In1 Signal
3 Blue GND Earth
Table 12: Connection; differential pressure sensor cable
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 twin-head pump system in the
common collector pipe. See “Twin-head pump installation/Y-pipe installa-
tion” [
} 163] section.
7.5 Wilo Net connection
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
ƒ
Wilo-Smart Gateway and pump
For details on connection, see the detailed instructions at www.wilo.com!
NOTICE
For Stratos GIGA2.0- D , the Wilo Net cable for twin-head pump communication is
factory-fitted to both electronic modules.
In order to establish the Wilo Net connection, the three H, L, GND terminals must be
wired with a communication cable from pump to pump.
Incoming and outgoing cables are clamped in a terminal.
Possible cable for Wilo Net communication:

Y(ST)Y 2x2x0.6 telecommunications cable
