Description
The Allen-Bradley 2198-DB08-F is an AC line filter designed for use with the Kinetix 5700 multi-axis servo drive system. It mitigates electromagnetic interference (EMI) and radio frequency interference (RFI) generated by the high-frequency switching of the drive’s inverter stages. Operating on a three-phase input, this filter helps ensure that the automation system complies with international EMC standards (such as EN 61800-3) by attenuating conducted emissions back onto the facility’s main power grid.

Engineering Overview & Integration Notes
In multi-axis Kinetix 5700 setups, the 2198-DB08-F is installed on the incoming AC line side of the 2198-Pxxx DC-bus power supply or integrated regenerative power supply. It provides essential attenuation for sensitive analog instrumentation or control networks operating near the high-power servo equipment.
Installation and Wiring Best Practices
To maintain effective attenuation profiles, physical mounting must minimize high-frequency grounding impedance:
- Proximity: Mount the filter as close as possible to the Kinetix 5700 power supply module. Keep the unshielded AC cables between the filter output and the drive input as short as possible (typically under 300 mm).
- Panel Grounding: Mount the filter directly to a bonded, unpainted galvanized steel backpan. Ensure that the integrated grounding surface of the filter housing forms a solid metal-to-metal contact with the panel to create a low-impedance path for high-frequency noise.
- Cable Separation: Route the incoming clean mains lines away from the noisy motor cables and the short link cables between the filter and the drive to prevent electromagnetic cross-coupling.
Field Note: High-frequency leakage current flows through the filter’s capacitive network to ground. Ensure that your industrial electrical system implements a robust equipment grounding conductor (PE) that satisfies local electrical codes for high-leakage equipment before applying power.
Frequently Asked Questions
Can I use one 2198-DB08-F filter to protect multiple independent drive clusters?
No. The 2198-DB08-F must be sized directly based on the continuous current draw of the specific Kinetix 5700 power supply it feeds. Ensure the aggregate continuous input current of the connected inverter axes does not exceed the filter’s 7.5 A rating. If your power supply capacity is larger, select a higher-rated filter from the 2198-DBxx series (e.g., 2198-DB20-F or 2198-DB42-F).
Is this filter required if my facility uses an isolation transformer?
While an isolation transformer isolates low-frequency voltage disturbances and limits common-mode noise, it does not adequately attenuate high-frequency conducted EMI emissions in the radio frequency spectrum. To fully comply with CE EMC directives and protect nearby micro-volt signal lines, the 2198-DB08-F filter should still be installed inline.
What causes an AC line filter like the 2198-DB08-F to fail prematurely?
Premature failure is typically caused by severe voltage transients (such as unmitigated lightning strikes or heavy inductive load switching on the same bus), extreme harmonic distortion on the mains, or operating beyond the continuous 7.5 A threshold. Check line quality and verify the thermal load in your electrical enclosure if the unit runs excessively hot.
