View of output busbar connections of frame size R7 (DC and brake busbars included)

WARNING! Fasten the output busbars to the insulating supports with M8x16 screws when
no cable lug terminal is connected, but with M8x20 screws when a cable lug terminal is also
connected with the same screw. Screwing an M8x20 screw without a cable lug terminal
through the busbar into the insulating support will break the insulating support. Fasten the
3
cable lug terminals elsewhere with M10x25 screws.
