Operation principle and hardware description 25 With the rotor-side converter (INU) it is possible to control the generator torque or speed and the power factor at the rotor/stator terminals, while the main task of the grid-side converter (ISU) is to keep the DC link voltage constant. While the rotor is accelerated by the wind and the speed is controlled by the pitch of the blades the converter can be started and controlled in DTC mode.

• UL 508A First Edition. Industrial Control Panels. Grid codes See ACS800-67LC wind turbine converters system description and start-up guide [3AUA0000059432 (English)]. CE marking A CE mark is attached to the converter to verify that the unit follows the provisions of the European Low Voltage and EMC Directives.
132 Technical data Validating the operation of a safety function IEC 61508 and EN IEC 62061 require that the final assembler of the machine validates the operation of the safety function with an acceptance test. The acceptance tests for the standard safety functions of the converter are described in chapter Planning the electrical installation.
600 V AC. The markings are attached to the converter when option +C129 (cULus) is selected. ETL marking according to UL508C up to 690 V AC is pending. Contact the local ABB representative when ETL marking is required. ACS800 multidrive modules: The module is cULus listed industrial control equipment. The approvals are valid with rated voltages up to 600 V.
CSA marking ACS800 multidrive modules: The module is cCSAus certified. The approvals are valid with rated voltages up to 600 V. The ACS800-67LC is not CSA marked. Contact the local ABB representative when CSA approval is required. C-Tick marking C-Tick marking is required in Australia and New Zealand.
Dimension drawings 135 Dimension drawings What this chapter contains This chapter contains example dimension drawings. Example lead-through drawings are included. The example drawing set helps in understanding the structure of the converter. WARNING! These drawings are not intended for mechanical installation and cable lead-through purposes as they most probably differ from a customized converter.
