In the 30072-450-61 Manual for the ATS48 on page 76, it shows contacts for ``KM1`` & ``KM2``. What are they?

Issue:
What are the the contacts labelled KM1 and KM2 feeding into the IC1 forward contactor and IC2 reverse contactor?

Product line:
Altistart 48, ATS48

Environment:
All enclosed

Cause:
Typo error in the instruction bulletin

Resolution:
This is an error in the manual. KM1 should be labelled IC1 and KM2 should be labelled IC2.
These are auxiliary contacts from the forward and reverse isolation contactors, used for electrical interlocking. This helps prevent closure of both contactors at the same time.
