Control Circuit
The control terminal board is equipped with screwless terminals. Always use wires within the specification listed below.
For safe wiring it is recommended to use solid wires or flexible wires with ferrules. The stripping length respectively
ferrule length should be 8 mm.

EMC Filter Installation
This drive has been tested in accordance with European standards EN61800-3. In order to comply to the EMC standards,
wire the main circuit as described below.
1. Install an appropriate EMC noise filter to the input side. See the table in
Technical Manual for details.
2. Place the drive and EMC noise filter in the same enclosure.
3. Use braided shield cable for the drive and motor wiring.
4. Remove any paint or dirt from ground connections for minimal ground impedance.
5. Install an DC reactor at drives smaller than 1 kW for compliance with the EN61000-3-2. Refer to the Technical
Manual or contact your supplier for details.
