4.2.1 Installation corresponding to EMC
• Controllers cannot be operated on their own. The EMC of
controllers on their own cannot be tested. Only the integration of
the controllers into a drive system allows a test whether the
objectives of the EC EMC Directive are met and whether the
device are in compliance with the law about the electromagnetic
compatibility of equipment.
• Lenze has done conformity tests with the controllers of the types
48x in certain, defined drive systems. These tested drive
systems are called "CE-typical drive system" in the following.
• Therefore, the user of the controller has the choice,
− either to determine the system components and their
integration into a drive system himself and to determine the
conformity under his own responsibility
− or to install the drive system according to the CE-typical drive
system as tested by the manufacturer of the controller and
declared to be in compliance.
• If you observe the following measures you can assume that EMC
problems caused by the drive system will not arise during the
operation of the machine and the EMC Directive and the EMC law
are satisfied.
• For any other installation, e.g.
− use of unscreened cables,
− use of collective RFI filters instead of the allocated RFI filters,
− omission of mains chokes
the machine or system must be tested whether it is compliance
with the EC EMC Directive and the EMC limit values are
considered.
• The compliance with the EMC Directive in the machine
application is the responsibility of the user.
