11. INPUT meter: This meter measures the AC voltage that the UPS system is receiving from the utility
wall outlet. The UPS is designed, through the use of automatic voltage regulation, to continuously
correct output voltage to connected equipment to a safe voltage output range. In the event of a
complete power loss, severe brownout, or over-voltage, the UPS relies on its internal battery to
supply consistent output voltage. The INPUT voltage meter can be used as a diagnostic tool to
identify poor-quality input power.
12. EVENT: This meter records the number of power outages.
13. MUTE: This icon appears whenever the UPS is in silent mode. The alarm does not beep during
silent mode until the battery reaches low capacity.
14. AVR (Automatic Voltage Regulation): This icon appears whenever your UPS is automatically
correcting low AC line voltage without using battery power. This is a normal, automatic operation of
your UPS, and no action is required on your part.
For more information about functions setup, please refer to the Function Setup Guide.
