Correct
Q: In addition to limiting the current draw from the mains during start-up of the pump, how does the soft-start functionality benefit operation?
A: It reduces the occurrence of water hammer in the pipes and minimises wear during start-up.
Correct
Q: What is a key installer benefit of the voltage protection in SQ/SQE?
A: Fewer service visits
Correct
Q: Which submersible pump was replaced with a Grundfos SQ?
A: A 4” submersible pump 
Correct
Q: Why is correct sizing of the submersible pump important?
A: Because an undersized pump will not be able to deliver the required flow and pressure and an oversized pump reduces energy efficiency, which increases operational costs.
Correct
Q: What is the benefit of a slow increase in speed?
A: It keeps the motor current low
Correct
Q: Why is it important to protect the pump from over- and under voltage?
A: Because large variations in power supply will damage the motor over time.
Correct
Q: How does the integrated dry-running protection work?
A: It automatically shuts down the pump if water shortage is detected.
Correct
Q: How long did it take to replace the pump with a Grundfos SQ?
A: 60 minutes
Correct
Q: How many times higher than nominal speed does the motor current reach during the first milliseconds?
A: Seven times higher
Correct
Q: By how much does the supply voltage decrease before the motor contactor stops the pump?
A: More than 10 %
