Wilo VeroTwin-DP-E Series User Manual

English
Installation and operating instructions Wilo-VeroLine-IP-E, VeroTwin-DP-E 79
NOTE:
The terminals In1, In2, AUX, GND, Ext. Off and MP meet the require-
ment for “safe isolation” (in acc. with EN61800-5-1) to the mains
terminals, as well as to the SBM and SSM terminals (and vice versa).
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 PE.
Differential pressure sensor connec-
tion
Tab. 4: Differential pressure sensor cable connection
NOTE:
The electrical connection of the differential pressure sensor is to be
fed through the smallest threaded cable connection (M12) on the
electronic module.
For a double pump or Y-pipe 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 respective collector pipe.
Procedure • Establish connections observing the terminal allocation.
• Earth the pump/installation in accordance with the regulations.
