APPLICATION ON UPS
1. UPS family, nominal rating and for RPA: P + No. UPS.
2. Load status: application on UPS, on utility, supply off,
manual bypass (appl. on manual dev.) and IEM mode.
Load = 70%
Autonomy = 7min
1. The load amount as a percentage of the nominal load
(referred to the most loaded phase).
2. Estimated battery backup time with actual load.
Udc Voltage
Udcp=400V Udcn=400V
1. Booster DC voltage information screen.
2. Booster DC voltage + pole (Udcp) and – pole (Udcn).
Battery Voltage
Ubp=273V Ubn=273V O
1. Battery DC voltage information screen.
2. Battery DC voltage + pole (Ubp), – pole (Ubn) and the
