Typo error in the instruction bulletin

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.
