4.7.1 Power Connection of Regenerative Inverter Systems

Standard
UL certification
Autotransformer
4 – 30
A line filter and commutating reactor are required for connecting regenerative
inverter systems. The use of a three-phase capacitor for additional mains
interference suppression is recommended. If you are using an UV 105 as an
additional 5-V power supply, you must connect it through an isolating
transformer via separate fuses.
Details for connecting the UV 105 see page 6 – 72.
In addition to the above-mentioned components, an overvoltage protector is
required for compliance with UL requirements. See "Overvoltage Protector"
on page 9
If the available supply voltage (L1, L2, L3, N) differs from the supply voltage
specified for the modules, an autotransformer is required to adjust the
voltages (see connection overview above). It must comply at least with the
connection specifications of the subsequent compact inverter.
