Implement the earthing in the outdoor
connection sleeve as per the installation drawing in the
documentation folder (Fig. 90).
It is imperative to install the earthing cable before the
connection sleeve is pushed onto the bar!
The 50 mm² earthing cable inside of the sleeve is only
necessary when earthing of the bus bar via earthing
nut applies (to check this see Appendix E on page
114).The two ring seal units are always earthed using
16 mm² earthing cables.
