22.5. BATTERY BACK-UP
A battery back-up with 10A requires one 10A power supply and one YR2.DIODE decoupling module.
Please note:
Set output voltage of power supply to 26.5Vdc minimum to avoid that the charger current flows to the load instead of
charging the battery. Use a fuse between battery and YR2.DIODE!
