Expansion port
The expansion port is designed for connecting the inverter to the external option module -
BOP Interface Module or Parameter Loader, in order to realize the following functions:
● Operating the inverter from the external BOP
● Cloning parameters between the inverter and a standard MMC / SD card
● Powering the inverter from the Parameter Loader, when mains power is not available
For more information about these two option modules, refer to the topics "
Parameter Loader
(Page
247)" and "External BOP and BOP Interface Module (Page 251)".
