3.2 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.
4. Maintenance, repair and disposal
As the controller does not contain any components to 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 unit must be disposed of in accordance with the
national environmental regulations.
5. Declaration of conformity
The CE marking is applied on the basis of the EMC directive EMC 89/336/EEC,
implemented in the standards EN 61000-6-4 (2001) and EN 61000-6-2 (2001) as
well as the low voltage directive LV73/23/EEC implemented in the standard EN
61010-1 (2001).
