MEP-805B reconfiguration

Can anyone please ahead some light on how to reconfigure then generator from 120 to 240v?
I know there is VOLTAGE SELECTION SWITCH behind the control board. Does anything need to be changed on the panel above where when L1-L2-L3 are?
There are little arrows that have volts on em, how to do switch that?
Thank you so much

Welcome to SS. Have you downloaded the manuals for this set?

Yes, all it has is this statement:
Ensure VOLTAGE SELECTION switch (9) is set to match voltage requirements.

I guess I should clarify my question...
How do I change Voltage Reconnection Terminal Board

The info you want is in the -10 manual. The switch is only for the control panel stuff. If you can't find it, LID or someone will help you. But first look. It's EASY.

I found the switch no problem. My only question is how to change the terminal board. Do I just unscrew all the nuts and move it up? Seems too easy

Yes. Remove nuts. Move board. Put nuts back on. Its in the TM. Don't make it hard.

Not knowing what the use of the genny will be, my question would be, are you sure you want 240v?

that is, 240v per leg, 416v across 2 legs, not 120v per leg, 208v across 2 legs
