The ABB 4NWP100203R0001 is an external battery module designed specifically for the PowerValue 11RT G2 1 kVA B UPS system. It packs four lead-acid batteries at 12 V each into a portable chassis, giving you extended runtime without stacking additional UPS units. The module measures 438 mm wide, 310 mm deep, and 86 mm tall — fits in the same rack footprint as the UPS itself.
Fit & Installation
The 438 mm width matches the standard 19-inch rack width, so it slides into the same bay as the UPS. Depth of 310 mm is shorter than many tower UPS cabinets, leaving room for cable management at the rear. Height of 86 mm (2U) keeps the stack tight. Input voltage is 12 V — the module connects to the UPS via its DC bus, not the mains. Four lead-acid batteries inside means you get a full battery string without external wiring.
