Modes of Operation
The UPS is designed to operate as a line-interactive system in the following modes:
A.
Normal -
The critical AC load is continuously supplied with filtered power. The battery
charger maintains a float-charge on the battery.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
