Power module
8.2.1
Battery start
The battery start function allows a UPS to be started from battery power in the absence of the main
input supply. It means the inverter is started with energy from the battery only and the load is supplied
with the battery energy via the inverter.
This function is typically used to restore the power to the electrical load if there has been a power
blackout.
The battery start function is implemented in the DPA UPScale ST family inside each power module
M10/M20.
Battery start procedure:
Before the inverter in each power module is started:
1.
Disconnect the battery from the UPS by opening the battery circuit breaker. If the battery is
decentralized, open the battery circuit breaker per power module.
2.
Disconnect the complete load from the UPS.
3.
After 30 seconds, close the battery circuit breakers.
4.
Once the battery breaker is closed, the power module(s) electronics are supplied and remain
powered for 10 minutes.
5.
Turn on the power module(s) by pressing the “ON/OFF” buttons simultaneously.
6.
The inverter(s) are now fed by the battery and the inverter LED indication is green.
7.
Connect the load to the UPS.
Note. The remaining energy stored in the battery is used to feed the inverter to power the vital load for
3 minutes. The autonomy time can be adjusted according to customer needs by a qualified service
engineer from the manufacturer or from an agent certified by the manufacturer.
