Technical Specifications
The document outlines the technical specifications for the PHF Harmonic Filter, designed to match the performance of Danfoss VLT® Series drives. The rated current is specified, along with the power of the variable frequency drive (VFD) and the description of the load, which is a symmetrical load of a converter with an uncontrolled B6 rectifier. The filter can handle an overload capacity of 160% for 60 seconds once per hour. The ambient temperature range is -25 to +45°C, with a temperature rise of 80K and an air-forced cooling method.

Standards and Compliance
The filter complies with several standards, including IEEE 519, EN 61000-2-2, EN 61000-2-4, IEC/EN 61000-3-2, IEC/EN 61000-3-4, and IEC/EN 61000-3-12. It has an insulation class of H, a test voltage of 3.0 kV for 10 seconds, and an insulation resistance greater than 100MΩ at 1000VDC. The efficiency is greater than 0.98, and the noise level is below 72dB. The protection class is IP 20.

System Requirements
The system requires a total harmonic voltage distortion (THVD) of less than 2% and a line voltage unbalance of less than 1%. The rated voltage is 400V, with a voltage range of 380-415V and a rated frequency of 50Hz. The filter is designed for a three-phase system.

Installation and Connections
The document provides details on the electrical installation, specifying that L1, L2, L3 should connect to the grid side, while L1', L2', L3' connect to the VFD side. Terminals A1, B1, C1, A2, B2, C2 are short-circuited by default but can be reconfigured for capacitor bypass to improve power factor when there is no load.

Dimensions and Mounting
The document includes dimensions and mounting instructions, emphasizing that technical specifications in the drawing are without obligation and subject to change without notice. General tolerances conform to DIN 7168-m.

Additional Features
The PHF series harmonic filters, including models PHF 005 and PHF 010, contain various terminals for mains, output to the frequency converter, optional capacitor disconnect, and temperature switch connections. The document also notes the importance of observing the protection clause to ISO 16016.
