Additional External Battery Packs (EBPs) may be connected to the UPS to extend the
runtime of the UPS when operating in the battery state. The single-phase 1-3kVA VRLA
UPS units support up to 4 EBPs. EBPs are not supported on the 1-3kVA Li UPS units.
The single-phase 1-3kVA UPS units support a 24Vdc, 36Vdc, 48Vdc, or 72Vdc battery
pack depending on the UPS part number the EBP connects to. Each battery pack
contains two battery cartridges connected in parallel; therefore, adding one EBP to the
UPS will increase the runtime by at least 3 times. Each battery cartridge holds 2, 3, 4, or
6 12Vdc batteries connected in series depending on the battery cartridge voltage. 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 ground.
When an additional EBP is connected to the UPS, the total battery amp hours 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 cartridges
sets (P/N UVD024, UVD036, UVD048 or UVD072) for the
appropriate EBP. Battery cartridges must be changed in sets. Do
not mix old and new battery cartridges.
