Apply and brush on a thin, even layer of contact
grease compound to all contact areas on the contact
springs, but not on the curved tip of the contact spring
(the part of the spring that will make contact with the
contact tube within the connection sleeve (Fig. 58).

Insert the bolts with conical spring washers into
the drilled holes on the flexible connector. In the
process, make sure that the conical spring washers are
properly in place (Fig. 59).
For the conical spring washer to properly transfer the
pressure onto the bolted component, the domed side
of the washer must always face the bolt head or nut,
with the concave side of the washer towards the
object(s) being fastened (Fig. 59).
Installing the contact springs

Fig. 60: Positioning the contact springs
The contact springs must always be installed on the
side from which the connection sleeve is pushed on. In
the example shown in (Fig. 60),the connection sleeve
is positioned on the right, thus both contact springs are
mounted on the right side of the flexible connectors. It
is not possible to push against the contact springs, as
would be the situation in the figure on the right.
