In the truck. Never worked with iVue, but if it was an ALC project with controllers in just one building I would not install a PROT485. BTW Carrier controllers are made by ALC.

I did not leave the building I had all split systems so don't need right?

If you have it to use, it won't hurt. Think surge suppression - it isn't going to fix any problem you have right now, but, it might put a damper on nearby (not direct) lightning strikes. I would put as close to a solid ground connection as possible. If you can't find a way to ground it, don't waste your time putting it in.

does it matter where i put it, at the first controller or last controller or in between? the documentation is not real clear on that? thank you for ur help

[Mr_Greenjeans]

Although I would shoot for the location with the biggest risk (say, an elevator penthouse, or a fan in a doghouse) and then install a solid ground conductor; in your case it may not matter much, so put it where you can easily get to the best ground (shortest, straightest path). It does not even have to be in a controller's panel.
