Please see if the motor on your machine can be changed to 3-phase 220. The current model has too much power and cannot be used if it cannot be changed.

The wire connection method is as follows: Power supply > overcurrent protector > pressure switch > phase converter > motor. However, please pay attention to the wire diameter of the power wire. The power wire needs to be more than 8 square millimeters, and the motor wire needs to be more than 6 square millimeters.

It is recommended to use a 35A circuit breaker

This output can only be used for three-phase asynchronous motors. Any other equipment except three-phase asynchronous motors cannot be used. At the same time, the motor must be changed to three-phase 220. The other power supplies on your equipment should be able to use single-phase power supply. The only thing that cannot supply power is your motor, so if you have strong hands-on ability, this can still be used by you. This mainly depends on your hands-on ability.

No, it can't be used in a single phase installation for a Stiebel Eltron 3phase Hot water unit.
