When the input voltage is within an acceptable range, the UPS will provide pure and
stable AC power to the output. The UPS will also charge the battery in AC mode.
When input frequency is within 46 and 64Hz, the UPS can be set at a constant output
frequency of 50 Hz or 60 Hz. The UPS will still charge the battery under this mode.

When the input voltage exceeds the acceptable range or during a power failure, the
UPS will start supplying power from the battery while the alarm will beep every

in this case.
When UPS is in AC mode or CVCF mode, press and hold the Test key for 0.5 second.
