I couldn't resist the price.
I couldn't resist the price.
On EBAY as well under wire strippers....the ones with the yellow handles that strip and crimp too.....A$14.00....I got the BANGGOOD one in 3 days as it was probably a local stockist......having test used it for a hundred odd wire pieces I highly recommend it.....I'll see if I can post a pic.

You only need a Neutral if you are using 120v which is always good to have which can be used where needed, so if 120v is needed anywhere then yes add the neutral
The main Breaker should not be the only source for protection, if you used that only then you would not use a fuse in the feed to the VFD Drive
The On/Off switch can be a 2 Pole Breaker which you would have in your cabinet, this would serve both as protection and as a Switch

hahaha and i just PM'd you about this...
i do have a 120V receptacle in the area to power the PC and G540s... it comes from same panel but ran separate lines...
i was planning to use this

installed on the panel...

Al, i was just wondering how you going with this?
Ericks, i'm patiently awaiting parts...
received line filter:

getting rest of stuff by friday.
got the mock up mounted on a plywood to "test"
hoping to get some progress over the weekend.
thanks!

yea, hindsight kinda sucks...
wanted a 8 3/4" deep enclosure for the stuff... figured bigger = better...
received a 20x20x8.75" enclosure... yea... too big...
getting a 12x16x8.75 enclosure today.
the HY VFD with the POT knob is a bit deep...
just received the MOM NO and MOM NC switches and the contactor... ABB feels much nicer than the amazon/china-zon ones...
lol at me... using cheap VFD/Spindle and expensive switches... ha!

So minor update...
Created a mock up on a piece of plywood to test up to the EMI filter.
Please don't mind the messy wiring... this is just to see if it works...
Mounted the switches and indicator light (temporarily connected to the outputs of the EMI filter as indicator)
some Liquid Courage...
Voila, press GREEN then the contactor engages and LIGHT ON! woot!
red button disengages the contactor! WOOT!
had a minor issue... my previous wiring pretty much turned on the mini 12V PSU when i turned on the "isolator" AKA Red/Yellow thingy knob switchy...
so re-wiring such that the HOT for the PSU is connected to the un-used pole of the contactor as such...
so when the contactor is engaged, the 120mm Fan will power up and also thinking of connecting the 12V pump as well.
now to connect to VFD and get movement on the spindle.
Cheers!
Al

Run the Filter Ground to the VFD Ground
For your spindle Shielded wire clamp, you can just use a 360 degree clamp attached to the Ground plane once you do your final install, keep the insolation ( outer jacket ) on as much of the Spindle Cable as possible and only expose as much wire as needed to make the connection

Thanks for that info!
ok, so you mean the filter GND terminal on the RIGHT hand side connect to the VFD Ground.
now, i took a multimeter and checked the two screws on the plastic body that has GND symbol on it... seems they're not connected to any ground and it's there to serve as a grounding point? so to run Filter GND to VFD GND, connect to the "E" terminal on VFD, correct?
I was planning to use Cable Glands but even if i get something like this,
https://www.mcmaster.com/7802k24
i will have about 3" of exposed & unshielded wires inside the case from gland to VFD.
for the clamp method...
i found this at Allied...
https://www.alliedelec.com/product/k...8102/70183208/
applicable for my use to slide insulation off 1/2" and attach Spindle to Grounded Case using the above works?

Ok, placed order for the clamping style from Digikey.
https://www.digikey.com/product-deta...8102-ND/303956
and updated wiring diagram to make connection from FILTER GND to VFD GND
the clamp is will be attached to grounding plane (Case)
