Installation Instructions for SIS Bus Bar Systems A2MS001EN revision R05

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. 50
– page 62).
Installing the contact springs
……………
Fig. 51: Positioning the contact springs
12.
Position the contact springs over the flexible
connectors, with the tip on the opposite side from the
connection sleeve (Fig. 52/1), as if the contact spring
is an arrow pointing in the direction the connection
sleeve will be moved to cover the bus bar connection.
With properly filled Al elast contact discs between the
flexible connector and the bus bar flange (alternating
peaks and valleys on the contact discs), insert the
bolt/conical spring washer/contact springs through the
flexible connector, Al elast contact discs, and bus bar
flange.
The contact springs must always be installed on the
side from which the connection sleeve is pushed on.
In the example shown in (Fig. 51), the connection
sleeve is positioned on the left, thus both contact
springs are mounted on the left 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.
Installing the flexible connectors from the
other side
…………………………………….
Fig. 52: Greasing or brushing the threads
13.
From the other side of the bus bar flange, push
properly filled Al elast contact discs onto the bolts
(alternating peaks and valleys on the contact discs),
followed by the other flexible connector (Fig. 52/2),
onto the bolts. Clean any excess PFISTERER contact
grease compound P1 that may be on the bolt threads
from passing through the Al elast contact discs.
14.
Apply (with a clean brush) a thin layer of
Gleitmo 815 grease to all of the bolt threads. (Fig.
52/red marking).
15.
Slide the second contact spring onto the proper
bolts (Fig. 52/3) parallel to the first contact spring (Fig.
52/1).
16.
Slide the conical spring washers over the
threads of the bolts through the contact springs
(dome towards the nut, concave towards the contact
springs) and the other appropriate washers over the
remaining bolts.
When viewed from the side, the one side will be a
near mirror image of the other.
