The electronics of the rectifier unit is not linked to the interface.
The rectifier unit does not have a master or slave function.
NOTE
This interface is not provided for the start-up of the connected inverters!
If the X320 interface is to be used, the USS bus connection must be
formed (loop through rectifier unit X100 terminal 35, 36 to all inverters
X100 terminal 35, 36).
The interface cannot be operated until start-up of the inverters has
been completed (addressing of slaves has been carried out).
The following can be connected to the X320 interface:
