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.

OCKET
(
POWER SHARE
)
The UPS has an output socket which enables the automatic disconnection of the load in certain operating conditions. The
events that determine the automatic disconnection from the Power share socket can be selected by the user using the
UPSTools configuration software (see the sections
Configuration Software
and
UPS Configuration
).
For example, the load can be disconnected after the battery has been operating for a given time, or at the pre-alarm threshold
for end of battery charging, or when an overload occurs.
Safety notes
: when the UPS is switched on, if the output switch (SWOUT) is opened, the Power share socket will
remain connected to the mains.
If the manual bypass switch (SWMB) is inserted, the output switch (SWOUT) is opened and when the UPS is
shutdown, the socket will be disconnected.

OWER WALK
-
IN
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:
