4.5. On mains operation
During normal “On Mains Operation”, the UPS should display it’s
default screen which will show “AC Mode” on the top line and
the output voltage on the bottom line (unless changed by the
user);
Input and Output voltages will change dependant on the UPS
location a settings.
The UPS should make no audible alarm noise.
This then indicates that power is being supplied to the load and
the system is functioning normally.
If a further test is required then use the self-test function to
check the UPS operation. See “using the front panel” on page
