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

This was originally posted on APC forums on 12/9/2016


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

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.

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?
