5.2.2 Installation of a CE-typical drive system

Note!
The EMC characteristics of a drive system are
installation-dependent. For this reason pay attention to the
instructions on filtering, shielding, earthing and layout.

Note!
If a different installation is used, e.g.
ƒ usage of unshielded cables
ƒ usage of common RFI filters instead of the specified RFI
filters
the machine or the system must be checked for compliance with
EMC limits for the assessment of conformity with the CE EMC
directive.
Filtering
RFI filters reduce high-frequency interference to a permissible level.
ƒ Only use the RFI filter specified for the drive controller.
The selection of a suitable RFI filter is dependent on the load current:
Load current Order designation
≤ 8 A EZF3_008A002
≤ 10 A EZF3_012A001
ƒ Add further interference suppression measures if the motor cables are
longer than 50 m.
