TOEP C710606 50B - AC Drive L1000V - Quick Start Guide
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. 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
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. Make sure the ground conductor complies with technical standards and local safety
rules. When an EMC filter is installed, the leakage current exceeds 3.5 mA. Therefore
according to IEC61800-5-1, at least one of the conditions below must be satisfied:
• The cross section of the protective earthing conductor must be at least 10mm
2
(Cu)
or 16mm
2
(Al).
• The power supply must be disconnected automatically in case of discontinuity of the
protective earthing conductor
6. Install an AC or DC reactor for EN12015 compliance. See the table in
or contact your supplier for details.
