Introduction to 4100ES-S1 Cabinet, Continued
The basic 4100ES-S1 has a Fuse Distribution Board mounted on the SPS chassis and
connected to the Auxiliary Power terminals. See Figure 2-4. 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.
