Designation Assignment Notes
SBM
Individual run signal/collective run
signal, readiness signal and “mains
on” signal Potential-free individual run signal/collective run signal (changeover con-
tact), operation readiness signal is available at the SBM terminals (menus
<5.1.6.0>, <5.7.6.0>).
Contact load:
minimum permitted: 12 V DC, 10 mA,
maximum permitted: 250 V AC/24 V DC, 1 A
SSM
Individual/collective fault signal Potential-free single/collective fault signal (changeover contact) is avail-
able at the SSM terminals (menu <5.1.5.0>).
Contact load:
minimum permitted: 12 V DC, 10 mA,
maximum permitted: 250 V AC/24 V DC, 1 A
IF module interface
Terminals of the serial digital BA in-
terface The optional IF module is inserted into a multi-plug in the terminal box.
The connection is twistproof.
Table 13: Terminal assignment
NOTICE
The terminals In1, In2, AUX, GND, Ext. off and MP meet the requirement for “safe
isolation” according to EN 61800-5-1
– to the mains terminals
– and to the SBM and SSM terminals (and vice versa).
The control system is configured as a PELV (protective extra low voltage) circuit.
This means that the (internal) supply meets the requirements for safe supply isola-
tion; the GND is connected to PE.

Table 14: Differential pressure sensor cable connections
NOTICE
The electrical connection of the differential pressure sensor should be fed through
the smallest threaded cable gland (M12) on the electronic module.
For twin-head pump operation in a Y-pipe installation, connect the differential
pressure sensor to the master pump. Arrange the measuring points of the differen-
tial pressure sensor in the common collector pipe on the suction and discharge side
of the Y-pipe installation
6.7.7 Making the electrical connection
ƒ
Make the connections in accordance with the terminal allocation.
ƒ
Earth the pump/installation as per regulations.
ƒ
Reinstall any uninstalled safety devices, e.g. module cover!
6.8 Protective devices
WARNING
Risk of burns from hot surfaces!
The spiral housing and the discharge cover assume the temperature of the fluid dur-
ing operation. It may cause burns.
• Depending on the application, insulate the spiral housing.
• Provide corresponding guards.
• Allow the pump to cool down at ambient temperature after switching it off!
• Observe local regulations.
