Rectifier
The vendor must install the rectifier separately. Samsung can provide a
commercial rectifier at the vendor's request.
For the RS-485 interface service between the SPI-2213 and rectifier, the rectifier
must meet the interface protocol specified by Samsung. For other operations, the
SPI-2213 can communicate with the rectifier using User Defined Alarms (UDA).
