REDUNDANT AUXILIARY POWER SUPPLY FOR AUTOMATIC BYPASS
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.
PROGRAMMABLE AUXILIARY SOCKET (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.
POWER 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.
REDUCING THE LOAD (TO 200V AND 208V)
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:
