Yes, or something similar.  Make sure that you feeding the amp with the 
two sides of 240 V, NOT between hot and neutral or hot and ground.

I don't know the L7, so I don't know if it uses 120V for anything (like 
a fan), but the proper connection of 240V is two hots and a ground, NOT 
neutral.  Neutral should be connected ONLY if there's a 4th wire in the 
amp cable for that 120V fan.
