Filtre RFI triphasé série 8200 Lenze E82ZZ22234B210

Product Description and Application

The E82ZZ22234B210 (E82ZZ22234B210) is a high-performance three-phase radio frequency interference (RFI) filter engineered for integration with the Lenze 8200-series drive systems. This passive component is specifically designed to mitigate high-frequency electromagnetic noise, ensuring compliance with strict electromagnetic compatibility (EMC) standards in industrial environments such as automated manufacturing lines, material handling systems, and pump control stations. By effectively suppressing conducted emissions, the filter prevents interference with sensitive signal controllers and communication networks, significantly reducing unscheduled downtime caused by erratic drive behavior or signal degradation.

Technical Configuration

This hardware unit is designed for a robust industrial electrical profile, operating at a rated voltage of 500 VAC within a frequency bandwidth of 50 to 60 Hz. The device is rated for a continuous current throughput of 7.3 Amperes. Its internal architecture utilizes high-quality inductive and capacitive elements configured to provide optimal attenuation across the frequency spectrum utilized by Variable Frequency Drives (VFDs). The unit is housed in a compact, ruggedized enclosure optimized for heat dissipation in crowded control cabinets. It is intended for direct line-side installation to ensure the incoming power supply remains isolated from the switching noise generated by the inverter power stages.

Technical Specifications

Frequently Asked Questions

Is this filter compatible with all Lenze 8200-series drives?

It is specifically designed for the 8200-series, but compatibility depends on the drive power rating. Verify that the drive current rating does not exceed 7.3 A to ensure the filter operates within its thermal design limits.

Since this is a phase-out model, what should I do for long-term support?

While the E82ZZ22234B210 is in a phase-out stage, original stock remains available for legacy system maintenance. For new designs, consult the Lenze engineering datasheet for current-generation filter equivalents.

What are the primary symptoms of a failing RFI filter?

Common indicators include increased electromagnetic noise causing PLC communication errors, drive trip faults related to voltage spikes, or intermittent sensor signal jitter occurring specifically when the motor drive is active.

Does the orientation of the filter matter during installation?

Yes, for maximum efficiency, the filter must be installed as close to the drive as possible, with shielded cables kept to the shortest possible length between the filter output and the drive input.

Engineering Guidelines and Installation Best Practices

• Shielding Integrity: When installing the E82ZZ22234B210, ensure the cable shielding from the drive is clamped directly to the common ground or the cabinet backplane with a high-frequency contact clamp. Do not rely on thin "pig-tail" wires for grounding, as these act as antennas for high-frequency noise.

• Thermal Management: Despite its compact 0.98 kg design, the filter dissipates heat during operation. Maintain a minimum clearance of 50 mm above and below the unit to allow for sufficient air convection. Avoid mounting the filter directly above heat-generating components like braking resistors or reactors.

• Safety Requirements: Always ensure the supply power is disconnected and verified as zero-energy before commencing installation. Due to the capacitive nature of RFI filters, a residual discharge time of at least 5 minutes after power-down is recommended before handling terminals to prevent electric shock.
