Number Of Batteries
The number of batteries, EOD voltage, and float charging voltage must be consistent with the voltage selection
(380V/400V/415V), as shown in Table 6-2.
Table 6-2 Number of batteries
Parameter 380V/400V/415V
Number of cells (standard)
1.85Vdc/Cell, 1.62V/cell recommended
2.3Vdc/Cell, 2.27V/cell recommended

Battery Protection
Since external batteries are selected, please select a BCB with sufficient DC breaking capacity.
The external battery must be connected to the UPS via the BCB. The BCB can be closed manually and is equipped
with an electronic tripping device controlled by the UPS control circuit. In the case of rack-mounted batteries (or
batteries that are installed at a distance from the UPS cabinet), the BCB must be installed as close to the battery as
possible, and the length of the power and signal cables connected to the UPS must be kept to minimum.
The UPS provides the following advantages:
Safe, reliable battery isolation
Short circuit protection
If the inverter is locked because of battery under-voltage, the circuit breaker will be opened
automatically in order to avoid over-discharging the battery.
If the remote EPO button is installed, the EPO button can be used to open the circuit breaker
Protection against misuse
To obtain the required backup time, the batteries may be connected in parallel. In this case, the BCB must be
installed downstream of the battery parallel connection point.

Battery Installation and Connections
Battery Installation
1.
Before installation, check the batteries for damage, inspect and count the accessories, and carefully read this
manual and the user manual or installation instructions provided by the battery manufacturer.
2.
There must be a vertical gap of at least 10 mm between the batteries in order to ensure the free circulation of the
ambient air between the batteries.
3.
A certain amount of clearance shall be maintained between the top of the batteries and the next layer in order to
facilitate battery monitoring and service operations.
4.
Install the batteries starting from the bottom layer and working upwards, in order to avoid creating a high centre
of gravity. The battery shall be properly installed and protected against vibration and/or impacts.
To avoid risks, we recommend using a VERTIV BCB for your external battery.
Only trained personnel may operate and service the battery circuit breaker.
