11.4 Aluminum contact points and cupal disks
11.4.1 Introduction
The following components have aluminum contact points:
●
Preconnected choke
● Chopper choke
● DC bus choke
Aluminum contact points require a specific screw connection for establishing
contact.
11.4.2 Preparation
The aluminum contact points come prepared for instant connection and do
not need to be adapted when installed for the first time. The contact points
are clean and have an anticorrosive coating.
The components with aluminum contact points come with bimetallic cupal
disks. Cupal is a composite made of copper (Cu) and aluminum (Al).
Use cupal disks whenever contact is established between the aluminum con‐
tact point and any material other than aluminium.
Clean both sides of the cupal disks with abrasive fleece before connecting
them, and then grease the cupal disks with a thin layer of contact grease.
If the connection is opened after operation, abrade and grease the connec‐
tions and the cupal disks again.
11.4.3 Cupal disk
The aluminum side of the cupal disk always has to have direct contact to the
aluminum contact point!
If contact is established on both sides of the aluminum contact point, also use
a cupal disk on the opposite side.
