7 Introduction 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). If the end of battery power was rea[...]

8 Introduction inverter shutdown or overload See figure 9 for devices or installations operating in on-line mode with a bypass AC source. Fig. 9 single-UPS unit (on-line mode) ■ in the event of a UPS shutdown (initiat- ed by the user or by an internal protective device), the load is automatically trans- ferred to the bypass AC source. If transfer[...]

9 Introduction operation with an engine generator set See figure 1 1 below . If a stand-by generator is included in the installation, it is generally started automati- cally in the event of a normal AC source failure and connected to the main low volt- age switchboard. It is disconnected when normal AC source power is restored. With such a system, [...]

27 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. The backup t[...]
