Not sure about the wire diagram, power in

[onecut]

.
Do I need a fused switch, fused disconnect switch box or power filter, just not sure.

This is what I have.

4-Axis DIY NEMA 34 Electronics Kit
Drive Type: G203V
PMDX-134 4-axis Motherboard
Ethernet SmoothStepper
Cable Configuration: Ribbon Cable (DB25 to LPH26)
PRO Rack and Pinion Drive, NEMA 34
Emergency Stop

This is the wire diagram. What's in the red box is what I'm having problem with.

The big red box is a switch with EMI filter, like the picture above shows. The small red box is... I have no idea about that one.

Hi Onecut

do you have a link to the original wiring diagram ?

in the small red box on the diagram you posted
it looks like there are six earth connections that could possibly be either
six DIN terminals like this -



or

six earth studs to connect wire directly to a metal chassis

or a combination of both DIN terminals and chassis mounted studs

if CNC ROUTER PARTS provide a physical layout diagram of the control box it should make it clearer what they have used

Thanks A_Camera,
You made that easy.

Hi onecut

the link didn't work but I have found these -
wiring diagram PDF


and layout PDF which has the information your looking for



John

PS

location of earth terminals PE1 to PE6

Thanks John-100
I thank I go it. It's tying the green ground to all sides and the back plate of the box with the white neutral as well correct?

[onecut]

Also John-100 all the numbers in circles around them in the wire diagram is that a description of the item and if so were can I find the description?

The neutral should Not contact ground, the only place it would be connected in N.A. is in the service panel.

Hi onecut

I have not found any other reference to the numbers in the circles on the wiring diagram
when I search the cnc router parts web site ,

but I'd guess they are inventory reference numbers for all the parts used in all CNC Router Parts products

alternatively they may be just part numbers for your machine

That's what I thought to but in the small red box on the wire diagram,
It looks like the com. side of the power supply ( Mean Well SE-1000-48) goes to ground. Is that correct?

In the USA, do not connect WHITE to GREEN (Earth Ground) in connected devices.

This is a requirement in some other countries, NOT in USA.

In the USA, the WHITE bonds to Earth Ground inside power distribution panels, NOT in connected devices, such as CNCRouterParts motor controller boxes.

Ok thanks,
That's what I thought. Guess I'm just reading the wire diagram wrong.
just wanted to make sure.

Can anyone tell me the model number and/or amp size of the switch in the pic above?

Schaffner FN 284-6-06 250 V/AC 6 A 0.45 mH with IEC contact.

Conrad part number: 398664

There are other types as well, if you need more or less Amps but I bought the one above for my machine.

As myself and others have stated neutral only connects with ground in the service panel.
There is an exception however, for example where you have system fed from either 240v 1ph only, or say a 3ph system and do not have a 120v for control voltage and use a step down transformer, in this case you have lost the neutral, so it is permitted to set up a 'local' neutral by bonding one of the secondary leads to the earth ground conductor right at the transformer, this conductor is now the enclosure local neutral and this is the only place it should contact earth ground..
See the 480/120v transformer example from NFPA79.
