Emergency systems
The UPS can be configured in accordance with standard EN50171 (the Centralised Power Supply Systems)
standard.
Over the battery type, the autonomy and recharge times, in accordance with standard EN 50171 may be
selected 4 different mode of operation in order to adapt to all different system requirements.

CONFIGURATIONS
The available configurations are the following:
Single UPS
The group on single version, normally used for simple installation, can be expanded until 6 units (4 in 3/1 version),
to satisfy increases of the power load or to introduce the redundant level.
Parallel configuration
Up to 8 UPSs (4 units in the 3/1 version) can be connected in parallel to increase the power of the uninterruptible
power system (power parallel) or to enhance its reliability (redundant parallel).
The system is defined as “redundant parallel” when the stoppage of one or several UPSs does not determine the
loss of the power supply.
All the UPSs power the load simultaneously with automatic sharing of the current.
The units exchange information on the operating status and the sync signals means the connections in loop with
dual redundancy. This means that even in the event of the accidental interruption of both connections, only the
UPS affected by this interruption cuts itself off, while the other one continues to operate without any interference.
Maximum communication cable length between two UPS should not exceed 50 meters keeping in mind that
total length for the overall ring is 100 meters.
