Given that I already have an existing setup using P33 cables with a three-phase 380V power supply, does the M60 series have a compatible three-phase power supply unit (PSU)? Or will I need to convert my current setup to a single-phase power supply instead?

What is the maximum switching time (this is the switching time between different power sources (for example, the general network and the energy storage system)) between power supplies in milliseconds?
