Fitting the main busbars
The top half of the busbar support can now be fitted.
A brass clamp-strip or a washer is fitted to the top half of
the busbar support after which the top half of the busbar
support is clamped to the bottom half with two hexagonal
socket-head bolts M8 for each busbar support, see
figure 2-48.
Attention: The bolt-shank is given awhirl-sintered layer of
plastic, so that there can be no voltage transfer via the
fixing-bolts. Other bolts may not be used. The length of the
bolts for fixing the busbar supports depends upon the main
busbar.
In order to determine the length of the bolts see table.
