30 - 300 VDC.
Run-up time Depending on power 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 µs/cm (micro siemens).
Sound pressure level The sound pressure level is lower than the limiting values stated in the EEC Machinery Directive.
Radio noise
SQF comply with EMC Directive 89/336/EEC.
Approved according to EN 50081-1 and 50082-2.
Reset function SQF can be reset via CU 200 or by disconnecting the power from the power supply in 1 minute.
Power factor PF = 1.
Operation via generator
Voltage: 115 VAC, –10%/+6%.
The generator output must be a minimum of 1000 Watts.
Earth leakage circuit breaker
If the pump is connected to an electrical 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.
