Symmetra PX 40K - how can output voltage be configured?

Good day,

We purchased a refurbished Symmetra PX 40K system from an UK company and we've installed it in Switzerland. What I can see however is that while the system is perfectly working, it is not set to the correct output voltage in use in Switzerland, that is three-phase 230V AC. It is instead outputting 240+ V which wouldn't be a problem per-se, if not that I keep on getting "An input voltage problem is preventing a switch to bypass mode". 

I looked everywhere in the Web configuration and in the Telnet console but nowhere I can find a way to set the output voltage, could somebody tell me how to set this?

This is what can be read about voltages in the status page:

Input Voltage:	227.5 | 229.4 | 229.1 VAC [Phase L1 | L2 | L3]
Output Voltage:	239.7 | 240.2 | 240.1 VAC [Phase L1 | L2 | L3]

Any help would be deeply appreciated!

Thanks,

Giorgio

This configuration is done with the PowerView-display on the UPS front.

you need to change system voltage from 415V to 400V.

Thanks for the hint Patrik but unfortunately the front unit says:

Output voltage can only be changed on international UPSs.

This is self explanatory, any idea on how can the unit be told that it has to be an international version?

Can you find a "bypass limits" setting, perhaps under configuration->power settings? If possible, I'd decrease the lower limit so the input voltage stays within the bypass window.
