Installation

*For 2 transformer systems, cut and tape o 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.
