8.13Pop-Up Windows

Pop-up prompt windows appear when the user must confirm a choice or perform an operation. This section describes the pop-up windows.

8.13.1 From Bypass to Inverter Mode With Power Interruption

If the bypass voltage or frequency exceeds the synchronized range and utility voltage or frequency is normal, the inverter cannot be in syn- chronization with the bypass, and the output can transfer to inverter only after an interruption of about 15ms when the user presses the INVERTER ON button. Before transferring, the system will let the

user confirm whether the interruption can be accepted, as shown at right. If the bypass voltage returns to normal before the user makes confirmation, the UPS will transfer to inverter mode auto- matically. At the same time, the prompt window will close.

8.13.2 From Inverter to Bypass Mode With Interruption

If the bypass voltage or frequency exceeds the synchronized range and the UPS is in inverter mode, the user must confirm and accept the power interruption danger before pressing the INVERTER OFF but- ton to shut down the output of the inverter. The user can also cancel the shutdown operation, as shown at right. If the bypass voltage returns to normal before the user makes the confirmation, the UPS

will transfer to bypass operation mode automatically, and at the same time the prompt window will close disappear soon.
