3 Electrical Installation
EMC Filter Installation
This drive has been tested in accordance with European standards EN61800-3. Install the drive and 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 motor and control circuit wiring.
4. Remove any paint or dirt from ground connections for minimal ground impedance.
5. Install an AC or DC reactor for EN12015 compliance. Refer to the Technical Manual or contact your supplier for
details.

Main and Control Circuit Wiring
Wiring the Main Circuit Input
Note the following precautions when wiring the main circuit input.
• Use only fuses recommended in
• If using a ground fault circuit breaker, make sure the breaker is designed for use with AC drives (e.g., type B according
to ICE60755).
• If using an input switch, make sure that the switch does not operate more frequently than once every 30 minutes.
• Use a DC reactor or AC reactor on the input side of the drive:
• To suppress harmonic current.
• to improve the power factor on the power supply side.
• when using an advancing capacitor switch.
• with a large capacity power supply transformer (over 600 kVA).
