The UPS is equipped with a redundant auxiliary power supply that enables the UPS to run on an automatic bypass even
when a failure occurs in the main auxiliary power supply. If a fault occurs in the UPS shutting off the main auxiliary power
supply, the load is powered by the automatic bypass. The multiprocessor board and the control panel are not powered so
the LEDs and the display are off.

(
POWER SHARE
)
The UPS has an output socket that enables the load applied to it to be disconnected automatically under certain
operating conditions. The events that determine the automatic disconnection of the Power share socket may be selected
using the configuration software UPSTools (see the
Configuration software and UPS Configuration paragraphs).
For example, the socket can be disconnected after a given time of battery operation, or when the battery low prealarm
threshold is reached or an overload occurs.

The UPS has a Power Walk-in mode which can be enabled and configured using the software UPS Tools . When the
mode is enabled and mains power is restored after a period of battery operation, the UPS starts to draw progressively
from it so as not to stress (due to the peak) any generating set installed upstream. The transient time may be set from 1
to 30 seconds. The default value is 10 seconds. During the transient, the necessary power is drawn in part from the
batteries and in part from the mains, maintaining sinusoidal absorption. The battery charger is turned on again once the
transient has passed.

If the output voltage is set to 200V and 208V (see “Configuring the UPS” paragraph), the maximum power output of the
UPS is reduced with respect to its rated value, as shown in the graph below:
