How to Start Up UPS Safely After Repairing or Replacing Main Board
When the PCBA board is reinstalled after repairing or replacing a new one, it is more secure for UPS that input
source, no matter DC source or AC source, has some protection function such as current limitation or power
limitation in case the board is damaged again if it still has some potential defects. Here, to lower this risk, we
suggested you use our DC source,which has power limitation function, to simulate DC source to start UPS, if
everything is fine and almost same with the following specific data, then the board repaired or replaced is fine,
otherwise, please recheck it according to some suggestion we provide as below .
