Page 14: Operation In On-Line Mode
An electronic board continuously mea- sures the battery temperature and auto- matically adjusts the voltages. Note: In parallel Galaxy PW™ systems, the power drawn by the load is equally shared between the different units. Fig. 5 operation with the normal AC source down See figure 6. -
Page 15: Operation With The Normal Ac Source Restored
operation with the normal AC source restored See figure 7. When normal AC source power (1) is restored or its voltage returns to within specified tolerances, the system automati- cally returns to its normal operating mode described above (on the condition it did not reach the end of battery power). -

Page 35: Utilization Via Teleservice
The battery capacity is the value mea- sured by the UPS microprocessor. It is expressed in Ampere-hours. This value changes over time depending on the para- meters of the battery itself and its environ- ment. This measurement is used to check that the battery is capable of supplying the rated power in the event of a mains out- age. -
