Enabling through a solid state relay

I am trying to turn power on and off to my amps through a Solid state relay and 7i97 Enable+/-. I know this is not the proper way to set this up but it is just temporary and it helps me understand. I know I need to run this through and emergency push buttom kill switch though. I was just wondering if someone could verify my diagram or not? 

That should work

             Well I left out a few things and here is actually how it is

do you see any problems with it like this?

with my transformers I use an ntc thermistor to compensate against the inrush current (one is 800w and the other is about 450w supplied from a 32A type C circuit breaker)

I don't like using SSRs in this sort of application and prefer a electro/mechanical contactor (high current relay)

the reason being is because an SSR normally looses the a bit of the AC waveform before the triac fires (even with a SSR which have a zero crossing firing triac

a SSR also does not actually go fully off.... there is a leakage current, this is not normally a problem, just don't ever work electrically on the output of the SSR and disconnect a wire while it is live upstream.

hence I like a contactor in most applications as it is a positive (full) disconnection device.

appreciate everyone does their own thing but it's best to understand all the pros and cons, then you can make an informed decision

they are glenteck SMA7215

you probably want to be very careful with the DC side of that circuit.

120v AC becomes almost 170v DC.

I have had a lot of shocks with 240v AC over the years (used to be an electrician / technician). only a DC belt came close to killing me which was an emergency lighting circuit. AC will tend to throw you away but DC will hold your muscles in spasm which is what happened to me, had I not been working with another quick acting spark I would not be here who just charged at me.

be very careful and give the capacitor time to discharge and or check it's discharged with a crowbar test.
