Question: What is the preferred way to wire a Magna 3 pump?

Answer: The Magna and all other E-Solutions series are instructed to be powered on continuously and then enabled through a contact. The power feed is wired as shown below in the diagram. Be sure to use stranded instead of hard wire to eliminate the potential problem of having the green connector becoming loose by the hard wire pressing against the cover. This is often the cause of having the Undervoltage Alarm error code (75) appear.

The contact for enabling the start/stop is pictured below:
