The basic 4100U-S1 has a Fuse Distribution Board mounted on the SPS chassis and connected to the Auxiliary Power terminals. This provides four sets of supply terminals, each individually fused at 1A, but the collective capacity is still limited to 2A from the Auxiliary Power supply. The fuses are not directly supervised.
