So, I have a teknomotor spindle with a Hitachi WJ200 VFD and in conversations with the tekno rep, he was always pushing me to add a line reactor to the system saying that it will extend the longevity of the spindle by quite a bit and that just everything would be better. They don't distribute line reactors so I'm assuming he was being honest. A line reactor was only $100 so I picked one up.

Question is on the wiring and mounting. I currently have the thing bolted to my work bench and it is not grounded. There is no separate ground lug on the transformer.

Is this a disaster waiting to happen or am I ok with this setup? Do I need to make a grounded metal box for this and tie it to the chassis of the reactor or anything?

TIA,
