Note: The position for a given output fuse is determined
by how that output is switched. If the output is switching
+VDC, the fuse for that output should be in the “Positive
Switching” position. In this example, the Green LED
indicator for that output would light. If it is switching -VDC,
the fuse should be in the “Ground Switching” position. In
this example, the Amber LED indicator for that output
would light.
