When the output frequency is set to "CF", the inverter will output constant frequency (50 Hz or
60 Hz). In this mode, the UPS will have no bypass output but still charge the battery.
When the input voltage/frequency is beyond the acceptable range or experiences a power failure, the
UPS will provide backup power from the battery. The alarm will beep every 4 seconds.
