Fusing
Internal 5.0 A fuse per group. Part # 043502405. For the
location of the fuses see Fuse Locations, p. 678.
External Each group is protected with a 5 A fuse to protect the
module from catastrophic failure. The group fuse is not
guaranteed to protect each output switch for all
possible overload conditions. It is recommended that
each point be protected with a 3/4 A, 250 V fuse,
Part # 57-0078-000.
