DC wiring instructions
In the UPS-cabinet of the Conceptpower DPA 500 there is no space provided for batteries, therefore
the battery will be external in either in cabinets or in shelves/racks.
Batteries can be either separate for each module or common battery within the same frame. It is normally
recommended for redundant Multi-Module systems to provide each UPS-Module with its own separate battery.
Before proceed with the wiring, make sure you have read and understood the chapter
