What does it mean when my Riello UPS is beeping and showing codes F31, F33, F60, L20, L21, L22, L23, L24, L40, L41, L42, L43, or L96?

If your Riello UPS buzzer is sounding continuously and the display shows one of the following codes: F31, F33, F60, L20, L21, L22, L23, L24, L40, L41, L42, L43, L96, the UPS is malfunctioning. If possible, disconnect the power to the load, switch the UPS off and back on again; if the problem occurs again, call the support centre.
