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
cable lug terminals elsewhere with M10x25 screws.
