(1) @ nominal load, minimum voltage of 164 Vac, battery charging
(2) @ nominal load, nominal voltage of 230 Vac, battery charging
(3) Mains/Battery @ load 0% -100%
(4) @ Mains/battery/mains @ resistive load 0% / 100% / 0%
(5) If the mains frequency is within ± 5% of the value selected, the UPS is synchronized with the mains. If the
frequency is outside the tolerances or operation is battery-powered, the frequency is the selected frequency +0.1%

To maintain the output voltage inside the precision range indicated, a recalibration may be necessary after a long
period in operation
When using a RS232 or USB communication cable to reduce EMI interference fit the ferrite supplied with
the UPS as follow:
1) Open the clip;
2) Place the ferrite as close as possible to the connector on the UPS side;
3) Place the communication cable inside ferrite groove with a turn (see figure);
4) Close the clip with communication cable inside (the cable must be remain in the ferrite hole).
