Usage

Mount the Micro Magic Auto Switch securely near your DOL motor starter panel.
Ensure the main power supply is completely switched off before making any wiring connections.
Connect the 440V power lines and motor starter terminals according to the provided circuit diagram.
Set the unit toggle switch to either Auto or Manual mode depending on operational preference.
Restore electrical power to allow the automatic system to monitor phases and initiate pump start/stop cycles.
In the event of single-phasing or severe voltage fluctuation, the preventer automatically cuts off power to protect the motor.
