Electrical connection
The cables of the digital input, the analogue inputs and the bus communication must
be shielded via the metal cable gland of the cable entry (Fig. 19, Items 4, 5 and 6). For
shielding, see Fig. 27.
When used for extra-low voltage cables, up to three cables can be passed through for
each threaded cable gland. Use the appropriate multiple sealing inserts for this purpose.
NOTICE
Threaded cable glands M20 and seal inserts must be provided on-site.
NOTICE
If two cables are to be connected to one 24 V supply terminal, provide a solution on-
site!
Only one cable per terminal may be connected to the pump!
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. OFF function.
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:
