4.2 Laying the supply and signal leads
As a basic principle all supply and signal leads to be laid separately.
Supply and ground leads to the controller and to the sensors / actuators to
be connected via a common neutral point.
Linking connections in the connector is not permitted and can lead to an
incapacitation of men and machines.

5. Maintenance, repair and disposal
As the Controller does not contain any components which must be maintained
by the user, the housing must not be opened. The repair of the controller may
only be carried out by the manufacturer. The disposal must be carried out accord-
ing to the corresponding national environmental regulations.
