Control Circuit
Use wires within the specification listed below. For safe wiring use solid wires or flexible
wires with ferrules. The stripping length or ferrule length should be 6 mm.
EMC Filter Installation
This drive has been tested in accordance with European standards EN61800-3:2004. 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 list above or refer to the
instruction 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 AC reactor at drives smaller than 1 kW for compliance with the
EN61000-3-2. Refer to the instruction manual or contact your supplier for details.
