Yep that's how I do it.!
Look at bottom din rail and on Far Left you'll see MCB's for toroidal Transformers, 24v psu, VFD along with Din terminal banks for Mains voltage.
On Far Right you'll see Din Fuse terminals for Drives and 0v & 24V bank of Din terminals.
Terminals in middle are for I/O to the machine, ie Limits etc.

Neil I have been thinking about it and Dean is quite correct I had forgot you will be using this in a works environment and needs to be done correct. If you had a fire the insurance might not pay out if it was not done ok.
So fit MCB's etc .. Clive

Neil You have passed the test :toot:very nice
Re: Comments sought on new build: A CNC Router for RC Gliders and Planes
Cheers Clive, except that I put a N label on the live terminal!!!!!

Ok then two points deducted.:encouragement:
Re: Comments sought on new build: A CNC Router for RC Gliders and Planes
Full marks though for it working, it's giving a nice steady 72V. It is taking a while for the capacitors to discharge but then there's no real load across them...

How can I safely discharge the capacitors with no load on them.......just to point out I've no resistor to drain it.....yet!!
Re: Comments sought on new build: A CNC Router for RC Gliders and Planes
Ok so I'm drawing up my wiring diagrams, ill start with the power to the PSU'S and 230V driver. I've got on and off push buttons I think that the off button needs to go in the safety part of the circuit as it needs to kill the power to the drives through the relay?

I blinking hate electronics!!!
Re: Comments sought on new build: A CNC Router for RC Gliders and Planes
For the wiring of the drivers to the din rail terminals and the motors to the din rail terminals is the below ok to do i.e. connect the screen to the earth core and just terminate it at the din rail terminals? Obviously both ends will have shrink wrap on them :) Oh and this is just a test piece.....no way near long enough!!!
