Note: Use separate mains systems for each power supply whenever possible.
17.5. Example: Battery Back-up
A battery back-up with 10A requires one 10A power supply and one 1606-XLSRED 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 1606-XLSRED.
