Wiring of oil pump.

Hi all,

Thought I get some advice/feedback as my electrical skills are very basic.I have an oil pump for my CNC slide ways which I plan to hook up to my MESA 7i76E. I want to switch the pump on when I am running an oiling routine prior to machining (or manually whenever I think it is good). I bought already a 24V DC / 240V AC solid state relay and plan to run a power cable together with a 24V signal cable to the pump. I think it all is pretty straight forward, however, I am confused about the attached Chinese wiring diagram which I found inside of the pump.I believe ‘T’ is the live connection and ‘R’ is the neutral connection. Assuming this is correct, they suggest to switch the neutral side (be it the relay or the feed switch). To my knowledge this seems NOT to be recommended with general household appliances.  electronics.stackexchange.com/questions/...-is-switched-neutral

I am currently considering of rewiring the inside of the pump that the switches are on the live side of things and before the fuse. Does that make sense?

PS: If anybody has a good link how to set up an oiling routine please don't hold back.

Cheers

No rewiring.
R and T are 2 phases of an RST 3 phase system, so both are live.

Thanks tommylight.

Autsch... I knew there was something obvious missing.
Looks like this thing is no use for me as i only have 240v single phase.
Or is there a 'non-expensive' way to make this 2 phase 220V, 50Hz work on 240v single phase? 

It should work with 240V, of course if the pump is rated for 220-240V.
In this case, cut the live wire.

Ok - so my initial line of thought wasn't wrong to rewire it and effectively making 'R' neutral?

It seems the max i can input is 250V AC according to this drawing but description says 220V. This is the pump:

A fair amount of this depends on where you live and what your "240vac single-phase" looks like.

Are you in the US and have 240-1P with two 120v 'hot' wires?

Or are your somewhere else and have a single 240v 'hot' conductor?

If you're in the US a very simple & cheap DPST (or DPDT) relay will work fine for this.
