Notices
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 permissible: 12 V DC / 10 mA,
maximum permissible: 250 V AC / 24 V DC, 1 A
Potential-free single/collective fault signal (changeover contact) is avail-
able at the SSM terminals (menu <5.1.5.0>).
Contact load:
minimum permissible: 12 V DC / 10 mA,
maximum permissible: 250 V AC / 24 V DC, 1 A
The optional IF module is pushed into a multi-plug in the terminal box.
The connection is twist proof.
NOTICE
The terminals In1, In2, AUX, GND, Ext. off and MP meet the
EN 61800-5-1 "safe isolation" requirement
– to the mains terminals
– and to the terminals SBM and SSM (and vice versa).
The control features a PELV (protective extra low voltage) circuit design.
This means that the (internal) supply meets the supply requirements for
safe isolation, the GND is connected to protective earth (PE).

NOTICE
Guide the electrical connection for the differential pressure sensor
through the smallest threaded cable gland (M12) on the electronic mod-
ule.
For a twin-head pump or Y-pipe installation, connect the differential
pressure sensor to the main pump. The measuring points of the differen-
tial pressure sensor must be arranged in the collector pipe on the suction
and discharge side of the twin-head pump system.
• Make the connections in accordance with the terminal allocation.
• Earth the pump/installation as per regulations.
• Reinstall any uninstalled safety devices, e.g. module cover!
