An external battery cabinet is available as an option (cat. no. 29B020128-PPE).

together.
The external battery cabinet contains two battery boxes identical to the built-in battery box.
Each battery box contains eight drawers of batteries. Each drawer contains eight batteries.
The external battery cabinet should be located as close to the UPS as is practical.
