SQF pump
Motor
Electrical data
30-300 VDC or 1 x 90-240 VAC, 50/60 Hz
Power supply to pump
30-300 VDC, PE.
1 x 90-240 V –10 % / +6 %, 50/60 Hz, PE.
Run-up time Depends on the energy source.
Start/stop No limitation to the number of starts/stops per hour.
Enclosure class IP 68.
Motor protection
Built into the pump.
Protection against
• dry running by means of a water level electrode
• overvoltage and undervoltage
• overload
• overtemperature.
Conductivity  70 s/cm (micro siemens).
Sound pressure level The sound pressure level of the pump is lower than the limiting values stated in the EC Machinery Directive.
Radio noise
The SQF complies with the EMC Directive 89/336/EEC.
Approved according to the standards EN 61000-6-2 and EN 61000-6-3.
Reset function The SQF can be reset via the CU 200 or by disconnecting the power supply for 1 minute.
Power factor PF = 1.
Operation via generator
Voltage: 115-230 VAC –10 % / +6 %.
The generator output must be
• minimum 1000 W (helical rotor pumps)
• minimum 1500 W (centrifugal pumps).
Earth-leakage circuit breaker
If the pump is connected to an electric installation where an earth-leakage circuit breaker (ELCB) is used as
an additional protection, this circuit breaker must trip out when earth fault currents with DC content
(pulsating DC) occur.
