4.8.1
BUS CONNECTION
The flange connections are drilled or not drilled in
accordance with the agreement
with
the customer.
The non-drilled connections must be drilled at the
construction site during installation.
Aluminium conductors achieve a good contact
between the connection surfaces if the non-
conductive oxide layer is removed, crossways, with a
clean, fine wire brush or "Scotch Brite" immediately
before bolting in place, and the oxidation is prevented
from returning with a thin layer of contact grease
(neutral petroleum jelly).
4.8.2
INSTALLATION WITH AL
ELAST CONTACT DISCS
In addition to the installation instructions from
PFISTERER, adhere to the installation drawing in the
documentation folder.
Al elast contact discs must not be re-used after being
removed.
The contact grease compound is not suitable for
greasing bolts. For greasing bolts, use high-
performance grease compound "gleitmo 815".
