What are terminals T3, T4, M2, and M3 for on the MDGF module (S48891)?

Issue:
Wiring MDGF Module

Product Line:
Molded Case Circuit Breakers

Resolution:
T3 and T4 are an iron core output to the trip unit for the purpose of powering the trip unit electronics.
M2 and M3 are an analog signal; their output is different for a 3 pole or 6 pole breaker and it communicates the level of GF to the trip unit.
MDFG trip does cause the Ig light to light up on the trip unit.
