For proper 6000W DC-input redundant power configuration, all four pairs of input wires for
one 6000W DC-input power supply must come from the same battery system (A feed); all
four pairs of input wires for the other 4000W DC-input power supply must come from
another battery system (B feed).
For multiple DC input power supply, each DC input must be protected by dedicated circuit
breaker or fuse. The circuit breaker or fuse should be sized according to the power supply
input rating and local or national electrical code requirements.
