AC power requirements for this FM amplifier

Hello folks. Sorry for being so demanding but it is better than burning stuff. We already talked here:

https://www.electro-tech-online.com/threads/fm-transmitters-and-rf-amplifiers.120678/


I almost finished my project but there is something I need to ask. This so-called amplifier has two AC power inputs in the back or so it seems. Actually one is definitaly for AC power input, but I'm not sure about the other. Could it be that this amplifier needs two connections to wall mains? Their type is different by the way. In the amplifier pdf file, it says the AC power requirement is 220/240 Vac +/- 10% single phase.

I'll post pics soon.

Okay I found out what it is ! It is just like how some PSU for pc's works. This "mains to driver" connector is a power outlet basically. Useless in my case.

Thanks for looking.
