AC Mode Description
LCD Panel
When the UPS is powered on, it will enter into this mode for a few seconds as the CPU and system
initialise.
When bypass voltage/frequency is out of acceptable range or bypass is disabled (or forbidden), the
UPS will enter No-output Mode if powering on or turning off the UPS. This means the UPS has no
output. The alarm will beep every two minutes.
When input voltage is within acceptable range, the UPS will provide pure and stable AC power to
output. The UPS will also charge the battery at AC mode.
