E. Conformance to European EMC Directive

In order to conform to EMC standards, the following methods are required for line filter application,
cable shielding and Drive installation.

The line filter and Drive must be mounted on the same metal plate. The filter should be mounted as
close to the Drive as practical. The cable must be kept as short as possible and the metal plate
should be securely grounded. The ground of the line filter and the Drive must be bonded to the
metal plate with as much bare-metal contact as possible.

For main circuit input cables, a screened cable is recommended within the panel and is also
suggested for external connections. The screen of the cable should be connected to a solid ground.
For the motor cables, a screened cable (max. 20 m) must be used and the screen of the motor cable
should be connected to ground at both ends by a short connection, again using as much bare-metal
contact as practical.

For a more detailed explanation, refer to Yaskawa document TD 4077, “Installation Guidelines For
EMC Directive using Yaskawa AC Drive Products.”

Table 1-4 and Figure 1-4 show the line filter list for EMC standards and the installation/wiring of the
Drive and line filter.
