DANGER! Risk of fatal electrical shock!
If the mains and SSM cores are both in the same 5-wire cable (Tab. 7.2, ver-
sion 1), the SSM core may not be operated with protective low voltage, oth-
erwise there could be voltage transmission.
• Earth the pump/unit according to regulations.
• L, N,
alternatively, the mains connection between two phases of a three phase net
earthed in a start point is possible with a triangular voltage of 3~230 VAC,
50/60 Hz.
• SSM: An integrated collective fault signal is applied at the SSM terminals as
potential-free normally closed contact. Contact load:
• Permitted minimum: 12 V DC, 10 mA
• Permitted maximum: 250 V AC, 1 A
• Switching frequency:
• Switch-on/off procedures via mains voltage 20 / 24 h
• Switch-on/off procedures via Ext.Off, 0-10 V or via digital, serial interface
20 / h
NOTE: If an individual motor is switched voltage-free in a double pump, the
integrated dual pump management is deactivated.
