two DC power modules are equipped but only one input is connected, the SRPU
displays alarm information for the unsupplied module.
z The AC power distribution box of the S7503 supports two power inputs, each of
which has a separate power switch. One input can only maintain the normal
operation of the corresponding AC power module. Only when the two inputs are
connected, the two AC power modules can work in 1+1 redundancy mode. When
two AC power modules are equipped but only one input is connected, the SRPU
displays alarm information for the unsupplied module.
2) S7506 and S7506R
z The DC power distribution box of the S7506 and S7506R supports two power
inputs, each of which has a separate power switch. Either of the two inputs can
maintain the normal operation of the three DC power modules at the same time.
When one input is connected, the three DC power modules can work in 2+1
redundancy mode. When two inputs are connected, the DC power inputs can work
in 1+1 redundancy mode.

When only one input is connected, the three AC power modules can work in 2+1
redundancy mode. When two inputs are connected, the AC power inputs can work
in 1+1 redundancy mode.
