My total load is 3 MVA, I am using 6 frame DPA 500 in parallel, So I wonder if I can using just 1 common battery system for 6 frame.
The DPA 500 UPSs accept a shared battery so using a common battery across six frames DPA 500 can be done. However, this is not recommended.
One common battery bank represents a single point of failure, and in practice the installation (wiring & fusing) of one battery system connected to 6 UPS frames is more complex than installing a separate battery per frame.
Therefore we recommend a dedicated battery bank for each frame.
