The Modular Battery Cabinet consists of 9 shelves, each of which may contain 4 Battery Units (BU). The BU contains 10 x 12V
batteries (refer to “Modules and Units” chapter).
The Modular Battery Cabinet has an electronic supervision system which, through voltage and current sampling, is able to
measure the condition and any anomaly within each of the Battery Units. The collected data is sent to the system through a data
bus and shown on the display of the Modular UPS Cabinet.
In addition, within the Modular Battery Cabinet there is an SWBATT disconnection switch which enables the BUs to be
disconnected from the Modular UPS Cabinet. The cabinet also features an opto-isolated input which enables the SWBATT switch
to be opened remotely.
CAUTION: each shelf of the Modular Battery Cabinet can be filled (with the 4 BUs) based on the autonomy requirements
of the system (up to a maximum of 9 shelves). The minimum number of fully populated battery shelves must follow the
rules set out in the table below:
