Replace ups battery detailed process 1, the charging unit 2 # U stop running, remove the UPS batteries GB 'in series with the fuse FU. 2. A fuse at both ends FU5, C point and connected diode V (2CZ 200A / 800V) .3, check the wiring is correct evacuation battery fuse FU. 4. Remove the fuse FU5, ups battery, the cathode of the diode check -WOM voltage of about 241V, for -WOM anode voltage of about 218V. 5. Disconnect SA1, remove the fuse FU3, FU4.6, start charging machine 2 # U, and nominal voltage to the DC bus by the charging unit 2 # U, battery GB 'parallel power supply. 7, remove the old battery from the battery panel group GB, ups battery pack, which is the positive and negative leads, respectively charger 1 # U of positive and negative corresponding connector. 8, start charging machine 1 # U, so that voltage and assembly of old batteries in parallel after the 241V. 9, disable the charger 2 # U, battery GB 'short voltage down to about 235V. 10, co-SA1, charger 1 # U, the old battery GB, the new battery G B 'parallel power to the DC bus. 11, off SA3, the new battery GB 'demolition screen mounted to the battery. 12, and will be connected to both ends of the fuse FU5 V diode connected to both ends of the fuse FU3. 13, mounted fuse FU4, charger 1 # U, the old and new batteries in parallel power to the DC bus. 14, off SA1, the new battery-powered UPS via a diode V to the DC link. 15, mounted fuse FU3, V diode is shorted. 16, remove the old battery. 17, co-SA1, charger 1 # U with a new battery, ups battery box, in parallel to the DC bus.

It remains ups battery charge state can improve the battery life of the UPS battery charger very important part, Changzhou ups battery, ups battery charging conditions have a significant impact on battery life. If the battery has been in a constant pressure or "float" type electrical charge state, the UPS battery life can increase the maximum degree. In fact the life of the battery state of charge is much longer than the life of a simple storage conditions. Because the battery charging can delay the natural aging process of the battery, so the UPS regardless of running or stopping state should keep the battery charged.
