Cable and conductor entries
Install cable and conductor entries only in pre-
drilled holes in which blind plugs are inserted.
Install the cable and conductor entries in such a
way that accidental loosening is prevented and
permanent sealing of the entry points is
ensured. Wherever cable and conductor entries
are not needed, be sure to close off the holes
with blind plugs.
Only cable/conductor entries and blind plugs
may be used that possess a separate EC Type
Examination Certificate issued by a recognized
European test laboratory in accordance with
European standards EN 50 014:1997 and EN
50 018: 1994.
