PRIMARY POWER WIRING:
- Maco 6500 is designed to operate from a 102-132 VAC, 50/60 Hz, single phase power source.  
Each module contains its own power supply which provides all operating voltages for the module 
circuitry.  Control equipment should not be connected to power sources subject to extreme voltage 
fluctuations caused by switching heavy loads. A voltage step-down isolation or voltage regulation 
transformer installed in the control cabinet is supplied.
