How To Start UPS Safely After Repairing or Replacing PSDR 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 utilize internal charger
(please make sure the output current jumper is configured with 4A for
4A-charger, and for 1A charger its version should be equal or higher than 71-300040-02G)
, which has power
limitation function, to simulate DC source to start UPS, referring the following SOP, 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 .

Notes:
This operating SOP is made base on 10K standard model and 20KL long run model, As Galleon 10K
and 10KL almost have the same frame structure and cabinet, so for 10KL long run model, please refer
this 10K standard model operating SOP. By the same token, for 20K standard model, please refer
20KL long run model operating SOP also.
Before starting any operation, please disconnect battery input no matter for standard or long run
model due to its potential electricity risk.
