Frame C and D Armature Fuse Signal Terminals
Terminals 81 and 82 on frame C and D drives are connected to the indicating
switch mounted on each of the internal armature circuit protection fuses. These
terminals can be connected to an external device to provide indication that the
fuses have opened. Alternatively, terminals 81 and 82 can be wired to drive digital
input terminals configured for 64 “Invert Flt” (via Pars 133…144).
