5. Click the Bypass Setup icon to modify the following values and select the configuration to be changed/saved. Click the
Back icon to return to the previous window, or click the Home Page icon to jump to the main page.
Bypass Volt Prot Lower Limit (%): When the difference between the bypass voltage and the rated voltage exceeds the
lower threshold for the bypass voltage, the system determines that the bypass voltage is abnormal and that bypass is
unavailable. The value can be -10%, -15%, -20%, -30% or -40%. The default value is -40%.
Bypass Volt Prot Limit (%): When the difference between the bypass voltage and the rated voltage exceeds the upper
threshold for the bypass voltage, the system determines that the bypass voltage is not normal and that bypass is unavailable.
Notes:
• When the voltage level is 120V, the value range is 10%, 15%, 20% and 25% (default).
• When the voltage level is 127V, the value range is 10%, 15% and 20% (default).
• Bypass Frequency Tracking Range: When the difference between the bypass input frequency and the rated frequency is greater
than this value, the system determines that the bypass frequency is not normal and that bypass is unavailable. The value range is
1%, 2%, 4%, 5% and 10% (default).
6. Click the Password icon to enter the user password setting interface. Input the old password and the new password, then
