Mounting
FLA battery
For closed lead acid batteries with the same charging voltages, the ventilation requirements
are higher. The requirements exceed the specifications listed here by a factor of 5. As
closed lead acid batteries are generally charged with even higher charging voltages, the
ventilation requirements increase even further.
The batteries can either be installed directly on the ground, or on a special battery mount.
Installing a battery with liquid electrolyte
With closed batteries, installation in an acid-resistant collecting tray is to be provided for
so that, in the event of a fault, leaking electrolyte cannot cause further damage.
Finally, install the battery bank in accordance with the installation instructions provided by the battery
manufacturer.
