until the bus connector of the expansion module rack can be 
plugged into the bus connector socket of the XC-CPU400/600 
or the basic or expansion module rack. Take care that the bus 
connectors of the module racks are completely engaged, in 
order to ensure reliable electrical contact. 

The spring contacts that protrude from the back of the module 
rack are intended to provide a ground for the modules. They must 
have a reliable electrical contact with the mounting plate.

Take care that the contact areas are protected from corrosion and 
– if you are using painted mounting plates – that the paint layer is 
removed from the contact areas.
