CNC Machine EMI Interference prevention

Hello,
I am busy converting my Bridgeport Series 1 Interact to LinuxCNC over ethercat. I have a Delta VFD11AMS21ANSAA which can be controlled via and ethernet port (Not sure how hard its going to be to get it working on LinuxCNC)
But as this is my first CNC machine build, what can I do to prevent back EMI and cross talk between the VFD and the other components like the PC, Servo drives and Beckhoff IO units.
Should the VFD be in a separate Cabinet?
Do I need special Ethernet cables or will normal ones Cat 5e work?
Any tips are appreciated.

Mains filter, ferrite cores on motor wires wound once or twice, proper grounding on all power modules and drives, signal wires shilded and grounded to one side only prefferably near the inputs, all grounds wired to a single point/rail in the box, avoid ground loops, short cables - never coiled.
