2. Functionality
In this section:
The external transfer switch replaces the internal AC transfer switch of each individual MultiPlus-II unit in the system. The system operates almost identically to one using the internal AC transfer switches.
Features such as UPS functionality, AC input current limit, PowerControl, and PowerAssist remain active.
