NOTICE: To ensure interference resistance, the total length of the 0-10 V control cable
should not exceed 15 m.

NOTICE: To ensure interference resistance, the total length of the PWM control cable
should not exceed 3 m.
• 0-10 V:
• Electric strength 24 V DC
• Input resistance of the voltage input >100 kOhm
• PWM:
• Frequency signal: 100 Hz-5000 Hz (1000 Hz nominal)
• Amplitude signal: 5 V-15 V (min power 5 mA)
• Polarity signal: positive / negative
• SSM: An integrated collective fault signal is applied as a potential-free normally closed
contact. Contact load:
• Permitted minimum: 12 V DC, 10 mA
• Permitted maximum: 250 V AC, 1 A
DANGER! Risk of fatal injury!
Improper connection of the collective fault signal (SSM) contact poses a risk of fatal
injury due to electric shock.
When connecting the SSM to the mains potential, the phase to be connected and phase
L1 on the mains connection cable of the pump must be identical.
• All connection cables must be installed so that they do not touch the pipe and/or the
pump or motor housing.
• Switching frequency:
• Interval between the switching times: at least 5 s.
• Switch on/switch off procedures via mains voltage £ 300 000 switching cycles during the
service life (80 000 operating hours).
• Switch on/switch off procedures via Ext. In, 0-10 V or via PWM £ 500,000 switching cycles
during the service life (80,000 operating hours).
