Collective fault signal (SSM)
The contact of the collective fault signal (potential-
free normally closed contact) can be connected to a
building automation system. Internal contact is closed
in the following cases:
▪ The pump has zero current.
▪ There is no fault.
▪ The control module has failed.
DANGER
Electric shock!
Danger to life through voltage transmission if mains
and collective fault signal line are led together
through a 5-wire cable.
▪ Do not connect SSM pipe to protective low voltage.
▪ Use 5 x 1.5 mm² cable.
Connection
▪ minimum permitted: 12 V DC, 10 mA
▪ maximum permitted: 250 V AC, 1 A, AC 1
During connection of the SSM pipe to the network po-
tential:
▪ SSM phase = live wire L1

Connect
DANGER
Electric shock!
During connection of the pump risk of death from
electric shock!
▪ Disconnect power supply before starting work.
▪ Only allow qualified electricians to carry out electrical
connection.
