115 or 230V?

[Symphysodon]

Hello there,

I've bought one of your 520W Powerstream PSU's but now I'm not sure how to set the button which determine the input voltage.

I'm living in Europe, and so i have to configurate the PSU for 230V input voltage, but how I have to set the button? The 115V or the 230V printing readable?

Thanks in advance.
