If you use a screw terminal cable breakout device, be sure to properly enclose all exposed conductors to avoid contamination and to reduce the risk of electrostatic discharge. I/O must utilize high quality shielded cabling (85% braid coverage minimum), which must be RF earth bonded as shown above.
Panel Mounting the E-AC Drive
The mounting panel must be properly earthed and paint must be removed from drive mounting locations. You must fasten the motor shield (braid) close to the drive’s heatsink.
