plug-in connection of the 3RW5 communication module until the securing mechanism on the
bus connector of the COM connecting cable latches into place.
Route the COM connecting cable in front under the 3RW50 soft starter and then on the side
next to the 3RW50 soft starter. Maintain sufficient distance from the main power connections
and ensure that your routing is EMC-compliant.
