again.

Press the unlocking lever at the lower side of the just mounted right module near the bus cou-
pler and pull it forward.
Turn all the locking lever of the bus coupler to be exchanged upwards.
Pull the bus coupler forward.
For

To mount the bus coupler put it to the left extension module and push it, guided by the stripes,
to the mounting rail.
