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 53x 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.
