EDUNDANT AUXILIARY POWER ADAPTER FOR AUTOMATIC BYPASS
The UPS is equipped with a redundant auxiliary power adapter which permits operation on the automatic bypass even in the event
of main auxiliary power faults. In the event of a UPS fault, which also can cause breakage of the main auxiliary power, the load
remains powered by means of the automatic bypass.
ATTENTION: the multiprocessor board and control panel are not powered in this mode; therefore, the LEDs and displays are off.
In this emergency condition, any disturbances present on the input line have repercussions on the load.

OWER WALK IN
The UPS is equipped with a Power Walk-In mode which can be activated and configured via configuration software. When this
mode is enabled, once the mains power is restored (after a period of autonomy), the UPS begins absorbing from it again
progressively so as not to threaten (due to the peak) for any generator group that may be installed upstream. The duration of the
transition can be set from 0 to 125 seconds. The default value is 10 seconds (when this function is active). During the transition,
the power required is drawn partly from the batteries and partly from the mains while maintaining sinusoidal absorption. The
battery charger is switched back on only after the transition is complete
D

ERATING OF POWER FOR

In the event in which output voltage is set at 200V or 208V NEUTRAL-PHASE, the maximum power that can be supplied by the
UPS undergoes derating with respect to the nominal power, as demonstrated in the following graph:
