Power and Segment Module LEDs
On Power and Segment Modules with fusing, the green LED indicates that the
main or segment voltage is present. In the case of fused modules (illustration right
above), the green LED indicates the main voltage is present at the line side of the
fuse. If the red LED is also on, there is no voltage on the load side of the fuse.
