Electrical Installation

 

The Model 9220 requires 24VDC, 4 Watt, 60 Hz, single-phase power.  A 24 VDC power supply is required and is generally included as part of the Model 9220 system. This power supply has a universal input that can accept between 60 and 265VAC.  Power should be applied in accordance with the electrical drawings that have been supplied or can be referenced on the Super Systems website.  Since each installation is unique to the site, the customer is responsible for providing adequate power and making it available to the Model 9220 power supply.
