operates in Bypass mode and supplies power to the load via the bypass.

Yes
the UPS, because the power consumption of this kind of loads is quite big.
• If the UPS is overload, the buzzer will beep twice every second.
• If the UPS is overloaded, please remove some loads immediately. It is
recommended to have the total loads connected to the UPS less than 80% of
its nominal power capacity to prevent overload for system safety.
• If the overload time is longer than the acceptable time listed in spec at AC
mode, the UPS will automatically transfer to Bypass mode. After the overload
is removed, it will return to AC mode. If the overload time is longer than the
acceptable time listed in spec at Battery mode, the UPS will enter into fault
status. At this time, if bypass is enabled, the UPS will power to the load via
bypass. If bypass function is disabled or the input power is not within bypass
acceptable range, it will cut off output directly.
