This feature is used only in the standby mode. The brownout protection feature allows the UPS to
switch to inverter power from utility power to the cabinet without running off of batteries when utility
power is experiencing certain brownout conditions. When the input voltage falls below 100VAC ±2V or
rises above 130VAC ±2V, the UPS switches over to inverter power but is still running off of the utility
power. As soon as the utility voltage falls below 88VAC ±2V or rises above 135VAC ±2V, the UPS then
begins to run off of battery power. This ensures that the cabinet will see no less than 100VAC or more
than 130VAC and the UPS will not use battery power if the utility voltage drops in this window.
