*For 2 transformer systems, cut and tape off one transformer. If transformer safety circuits are only in one of the systems, remove the transformer of the system with NO safety circuits. If required, replace remaining transformer with a 75 VA Class II transformer. After disconnecting one transformer, the two commons must be jumpered together.
