The built in hardware phase synchronization is between the sync input and PE.
The user must connect the synchronize line L1 with the sync plug.
The synchronization is based on a 3-phase system where neutral is connected to
PE in the supply system.
As Standard
line L1 is connected to the sync
plug. For coupling other lines, the
UCS500 hardware will automatically shift the phase angle in relation to the used
coupling.
The tables below shows the correction angels considering the phase in a 3-phase system with connected L1 to
the sync input. The UCS500 firmware will automatically add the correction angle to the settled value.
Synchronization: L1 to Sync input

The correct phase angle will be set automatically from the UCS 500N.
