Operating states
NOTE:
The block diagrams include the optional SBP static bypass. It is integrated into the system depending
on the UPS design.
2.2.1
Normal operation
In normal operation, all the installed UPS modules supply the connected consumers, with the power
demand being spread equally across all the UPS modules.
Online operation
The mains feeds the rectifiers.
The rectifiers provide the DC voltage for the inverter and charge the battery.
The inverters supply the load at the output with the necessary energy.

2.2.2
Module error
The mains feeds the rectifiers.
The rectifiers provide the DC voltage for the inverter and charge the batteries.
In the event of a module error, the module concerned is shut down and the load is distributed
across the remaining modules, provided enough reserve is available. If not enough reserve was
available, the UPS would switch to overload mode and so supply to the consumers would no
longer be assured. For that reason, we recommend running a redundant 20kVA module in
parallel.
