Note: Use separate mains systems for each power supply whenever it is possible

A battery back-up with 10A requires one 10A power supply and one YR2.DIODE redundancy module.

Please note:

Set output voltage of power supply to 26.5Vdc minimum to ensure, that the load current is delivered from the power

supply and not from charger (battery). Use a fuse between battery and YR2.DIODE!
