6.6.1 Bypass contactor (electrical DC link
coupling)
Using the electrical DC link coupling, it is possible, for a
multi-motor group with common DC bus, to connect or
disconnect a converter with DC supply input to the DC
bus.
This option is used when an inverter section has to be
replaced.
Binary output -X9:4,5 is provided to control the contactor.
