Installation and operating instructions Wilo-Stratos GIGA 29
NOTE:
The control is designed as a PELV (protective extra low voltage) cir-
cuit, meaning that the (internal) supply meets the requirements for
safe supply isolation; the GND is connected to M (Ground)
Differential pressure sensor
connection
NOTE:
The electrical connection of the differential pressure sensor is to be
fed through the smallest threaded cable connection (M12) on the
module.
For a double pump or Y-pump installation, the differential pressure
sensor is to be connected to the master pump.
The measuring points of the differential pressure sensor of the master
pump must be on the suction and pressure side of the double-pump
system in the corresponding collector pipe.
Procedure • Establish connections observing the terminal allocation.
• Ground the pump/system according to regulations.
