E82ZZ75112B210 Lenze 8200-series RFI Filter 3.4 Amp

Product Overview

The E82ZZ75112B210 (E82ZZ75112B210) is a high-performance Radio Frequency Interference (RFI) filter engineered specifically for the Lenze 8200-series frequency inverters. This essential electromagnetic compatibility (EMC) component is designed to suppress conducted high-frequency interference, ensuring that your drive systems meet stringent industrial emissions standards. Primarily utilized in precision manufacturing, textile machinery, and automated assembly lines, the E82ZZ75112B210 manages electrical noise that can otherwise disrupt sensitive control signals and peripheral sensors. By effectively filtering the 3-phase power supply, it safeguards system integrity, prevents data corruption in communication networks, and significantly enhances the long-term reliability of the entire drive train.

Technical Configuration

The E82ZZ75112B210 features a robust 3-phase architecture rated for 3.4 Amp continuous current at 500 V. As an "obsolete" yet highly sought-after legacy component, it is built with high-grade inductive and capacitive elements that maintain stable attenuation characteristics even under fluctuating load conditions. The filter is designed for footprint or side-mounting, allowing for a space-saving installation directly adjacent to the 8200-series inverter. Its internal circuitry is specifically tuned to the switching frequencies of Lenze power modules, providing optimal suppression of electromagnetic interference (EMI) across the 50/60 Hz spectrum. This hardware is critical for applications where the inverter must operate in close proximity to sensitive electronics or within residential/commercial power grids.

Technical Specifications

Technical FAQs

Is the E82ZZ75112B210 required for every 8200-series installation?

While the drive will function without it, this filter is mandatory if the installation must comply with European EMC Directives (EN 61800-3). It is highly recommended in environments with sensitive digital logic or analog signaling to prevent erratic system behavior.

Can this 3.4 Amp filter be used with a higher-rated Lenze inverter?

No. The RFI filter must be matched to the rated input current of the inverter. Using a 3.4 Amp filter with a higher-power drive will lead to saturation of the filter inductors, overheating, and potential failure of the filter and the drive's input stage.

What are the consequences of using this "obsolete" part in new systems?

While the part is technically obsolete, it remains a critical "form-fit-function" replacement for maintaining existing 8200-series installations. For new system designs, it is advisable to consult current Lenze documentation for the i500 series equivalents, though the quality of this legacy filter remains a benchmark for EMI control.

Engineering & Installation Guide

• Cable Length Restrictions: To ensure maximum effectiveness of the E82ZZ75112B210, keep the cable length between the RFI filter and the inverter as short as possible (ideally under 30 cm). Excessive lead length introduces parasitic inductance, which can bypass the filter’s suppression capabilities at high frequencies.

• Effective Grounding: The filter housing must have a low-impedance connection to the mounting plate. Remove any paint or oxidation from the mounting surface to ensure a "metal-to-metal" contact. This provides the necessary path for interference currents to return to the source rather than radiating through the cabinet.

• Separation of Leads: Strictly separate the "clean" line-side cables from the "noisy" load-side cables (those leading to the inverter and motor). Never run input and output wires in the same duct, as high-frequency noise can couple back onto the mains side via mutual induction, neutralizing the filter's benefits.

• Thermal Considerations: Ensure the filter is mounted vertically to allow for natural convection. While the 0.79 kg unit is compact, it can generate localized heat during continuous full-load operation. Maintain at least 100 mm of clearance from other heat-generating components.
