External battery cabinet option
It’s recommended to install external battery cabinets next to the UPS unit. The external battery can be placed on either side of the UPS unit. Check before the installation that the battery voltage values in the type plate of the UPS and external battery cabinets are the same. The cables are delivered with the external battery cabinet. See External Battery Cabinet (EBC) installation procedure.
Warning!
The UPS contains high DC voltages. A qualified person must do the connections between the UPS and the external battery cabinet(s). The battery cabinet is connected electrically in parallel with the internal batteries of the UPS.

Battery racks
