I need help with hooking up my Titan Helios 4!!!

[AnD1]

I got a 9 by 9 grow area in my basement, i got 4-1000w lights cooled hood, n a Titan Helios 4. I was wondering if i could simply hook up the controller to my 30A 250v dryer socket ever since all that is hooked n closer to my grow room, by plugging a 3p 240v dryer cord to the socket, and the 2 hots and ground into the titan controller? Will it be safe? The socket goes up thru electrical boxes and into a 30A circuit breaker! Heres pics of socket and boxes it goes thru before going up into the circuit box!






The socket comes into this left box

As I pointed out in the other thread, I can't see your pictures. However, the Helios 4 requires a 120/240 feed according to the instruction sheet (a neutral, (2) hots, and a ground), so your 3-wire 240v only supply will not work properly. The ground should not be used in place of a neutral. If you have easy access to the wiring, changing the feed wire & receptacle out to a 4-wire 120/240 circuit will work fine.
