Good morning Brian.
Hopefully you have finished the installation by now.
Anyway, what you describe looks like a 3 phase isolator. L1, L2, L3 (or R, S, T) are the supply-side contacts and T1, T2, T3 (or U, V, W) are the load-side contacts.
Although overkill, if it is a mechanical isolator switch, it is still usable for your installation.
- You have to connect your Live/Phase wire to L1 and also connect T1 to the #1 contact of your control board. L2, L3, T2 and T3 are not used.
- The other wire for powering your control board (Neutral - to contact #2) must be connected directly to the control board - not through the isolator.
- The Neutral/Protective earth wire of your power supply is connected directly to the earthing wires (green & yellow colored) of the motors - not through the isolator.

I also got an outside isolater switch for power to the panel. It has L1, L2 and L3 inputs and T1, T2 and T3 outputs for 220v. Would you be able to tell me where Live/Neutral/earth goes?
Thanks.
Brian,
Sav, already answered that: 1 is Live and 2 is Neutral (and even if you connect them the other way round no harm will be done to your automation - this is just a matter of proper installation).
