For this approach to work, you need to use identical filter models, and the connection must allow the filters to share the current equally.

The previously EMI filter installation guidelines and best practices can provide many benefits, including:.

Grounding Tips Grounding also called earthing, is a crucial part of a system and EMI filter installation where problems often occur. Flat wires, for instance, offer lower HF impedance than round wires do. Ensure that all the ground connections are as short as possible. Consider using a flat, braided ground strap, as these components provide increased surface area.

Use the largest available area as the ground conductor. The cabinet wall is often a suitable surface. Removing paint from mounting surfaces of the cabinets can help achieve a low impedance bond. To ensure safety and proper performance, make sure the power system ground is connected to the filter ground termination point before connecting any wires. Be sure to research and follow all relevant safety regulations related to grounding.

Examine all the connections in your low impedance grounding systems as part of your routine maintenance checks. Aim to keep power and control wiring separated.

Ensure that power and control wires do not run parallel. If cables must cross, ensure that cables cross at or as close to a right angle as possible. Route the conductors as close to the panel as you can. Ensure that the filter input and output conductors are separated. Keep input and output leads separated. Use shielded wiring if necessary, especially, on the side that needs to be protected from the radiated noise. Ensure that the shield of shielded cables is terminated at both ends. Keeping the following EMI filter installation recommendations in mind can ensure proper EMI filter performance: Mount the filter in a place that requires the shortest cable runs.

When the aim is noise mitigation, mount the filter as close to the EMI source as possible, whether it's a drive, uninterruptible power source, inverter or another component. The farther it is, the more wiring is available for noise to propagate. Bulkhead mount the filter to the chassis at the point of power entry with proper shielding, creating good input-output isolation.
