WARNING! The output busbars are fastened 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.
