1, the charger 2#U stoprunning, take off the UPS battery GB' serial fuse FU.
2. Connect diode V (2CZ200A/800V) at the A and C points at both ends of the fuseFU5.
3. Check the wiring and sendthe battery fuse FU.
4, take off the fuse FU5, diodeV series in the circuit, SA3, check the diode cathode -WOM voltageof about 241V, anode -WOM voltage of about 218V, diode reversecut-off. The DC bus is powered in parallel by the charger 1#U,battery GB and GB', but because the battery GB' is low, the DC loadis powered by the charger 1#U and battery GB.
5, disconnect SA1, take off thefuse FU3, FU4. Battery GB' instantaneously to the DC bus powersupply through diode V.
6, start the charger 2#U, andadjust its voltage to the rated value, DC bus by the charger 2#U,battery GB' parallel power supply.
7. Remove the old battery packGB from the battery screen, and connect its positive and negativeleads to the positive and negative poles of the charger 1#Urespectively in the nearby DC screen connection number.
8, start the charger 1#U, sothat it and the assembled old battery after the parallel voltage is241V.
9. Disable the charger 2#U, andthe voltage of the battery set GB' is reduced to about 235V for ashort time.
10, combined with SA1, thecharger 1#U, the old battery GB, the new battery GB' parallel tothe DC bus power supply, but because the charger 1#U and the oldbattery GB after the parallel voltage is higher than the voltage ofthe new battery GB', the load current by the charger 1#U and theold battery GB power supply, but because the diode V reversecut-off, No GB' backcharge to the new battery pack.
