3.1.2.2. Fusing
For AC modules, the main input fuse is located on the switching power supply mounted
to the carrier PC board and the protective cage may be removed for access to the fuse.
For DC modules, all fusing is located on the carrier PC board.
Always replace any fuse with same type and rating. Other fuses are present on the
board, and are designed for output fail-safe protection of the system. All output fuse
values are printed on the back side of the PC board to aid in replacement.
NOTE:
If a fuse does blow in operation, investigate the possible cause of the failure prior
to replacing the fuse, as there is adequate built-in protection margin.
