In the PSU 125 AC, fuse F1 supports currents of up to 5A. They are of
Fast Acting type, 250V. If necessary, only replace it with one of the same
specifications. The
F1000
output fuse
supports up to 15A. It is a Fast
Acting type, 86V. If necessary, also replace it with another one with the
same specifications.
In the situation in which both PSUs are present and the power inputs are
energized and operating with voltages within the specified range, the AC
power inputs will take precedence over the DC power input, regardless of
the connected slot.
In the situation in which both DC PSUs are present and the power inputs
are energized and operating with voltages within the specified range,
PSU 1 will be supplying power to the equipment and PSU 2 will be on
standby.
