Hi
Can you advise please regarding phase 3..

I've an auto hacksaw machine in my workshop.. The workshop runs on 240v supply..

The 240 volt supply runs to a Mitsibushi inverter as per pic below..
Phase 3 advice pls ima - EletriciansForums.net

This is wired to a New Brooks Compton electric motor which is 3 phase.. The plates details are.. T-D-A90SA..
50-60htz KW.75 220-240v
3.96 - 380-415Y

3.63 Amps -2.29 -2.20

The 3 phase connections are 3core and Earth ...316RS6....318 -415v


My question is.. Ideally I'd like to have an on off switch wired between the inverter and the electric motor so I can easily switch power on and off to the hacksaw..

Is this possible and if so what do I need to buy pls..

Many thanks..

I would have posted more pics but it seems I'm only allowed one...?
 
Why? How does it start and stop now?

Most VSD's don't like their output just being cut off, this varies between brands and as I don't use Mitsi often I can not comment.

At present I switch it on and off at the inverter, it's just the switch is small and fiddly..
 
Making something start and stop is easy. Doing it to the regs where all the paperwork, risk assessment, stopping catagory and all the other rubbish is the hard bit.
 
you could fit sa remote single phase isolator/switch to the incoming side of the inverter consideration should be given to emergency stop/s. this would entail the use of a contactor and some other bits. not a DIY job, tbh,.
 
Is this Saw for personal use only in a home workshop?
If NO, does the workshop have any Emergency stop control for all machinery?

Does it (or did it ) have any safety interlocks fitted on the saw?

You could use the Stop Start inputs within the Inverter for manual control.

The manual is available online with the connections identified.
