GE MM2 Motor Manager Complete Guide

Attention: If using VT input for power measurement at the same time, a secondary voltage independent of the motor direction must be provided to the voltage transformer (PT) (i.e. PT connected to the motor input terminal, not downstream of the contactor after forward/reverse switching), otherwise the voltage phase will be incorrect during reverse rotation.
