WARNING! Fasten the output busbars to the insulating supports with M10x20 screws when no
cable lug terminal is connected, but with M10x25 screws when a cable lug terminal is
connected as well. Screwing an M10x25 screw without a cable lug terminal through the busbar
into the insulating support will break the insulating support.
