External Battery Pack (UVP240, UVP480))
The External Battery Pack (EBP) has a positive-negative dual-battery structure. The
single-phase 5-10kVA UPS units support a 240V battery pack and the 3-phase 10-
20kVA UPS units support a 480V battery pack. Each battery pack has multiple battery
cartridges that make up a battery cartridge set. These battery cartridges in the set are
connected in series. The battery cartridge set for the 240V EBP has two battery
cartridges with 8 batteries and one battery cartridge with 4 batteries for a total of 20
batteries connected in series. The battery cartridge set for the 480V EBP has four
battery cartridges with 10 batteries in each cartridge for a total of 40 batteries connected
in series. A total of three wires are connected to the UPS unit from the EBP unit, the
positive and negative ends of the battery pack and a neutral that is connected to the
center point of the series batteries.
The UPS comes with one EBP unit. Additional EBP units may be connect to the UPS to
extend the runtime of the UPS when operating in the battery state. The 5-10kVA single-
phase UPS units support up to five EBP units. The 10-20kVA 3-phase UPS units
support up to eight EBP units. Additional EBPs are connected to the last EBP in the
chain.
When an additional EBP is connected to the UPS the total Battery Group number must
be appropriately set. All relevant settings may be performed through the WebUI or the
Front Panel Display.
Warning!
Ensure that the polarities are correctly connected to the UPS unit and
to subsequent EBP units. The battery cartridges cannot be mixed.
Please use the Panduit recommended battery cartridge sets (P/N
UVD240 or P/N UVD480) for the appropriate EBP. Battery cartridges
must be changed in sets. Do not mix old and new battery cartridges.
Battery Cartridge Set (UVD240, UVD480)
The battery cartridge sets for the EBP units contain either three or four cartridges that
make up the appropriate voltage for the specific EBP unit. Panduit recommends
changing all the battery cartridges in a system at the same time. Do not mix new battery
cartridges with old battery cartridges in the system. If you have multiple EBPs in your
system, then you should change the battery cartridge sets in all the EBP units in that
