Is there something I can query with the shop before I buy it?
Querying it with FreeNAS would be the best. LOL
If it is not a known good UPS, then it may require experimentation.
To work properly FreeNAS only cares about two signals: ONBATT and ONLINE.
You connect the UPS via serial port, make sure the right COM port is configured, and try the serial drivers one at a time (there are fewer serial drivers, that is why this process makes sense with serial interface in particular). Pull the UPS power plug from the wall, and observe the FreeNAS console, which should let you know that the UPS went on battery power. Then plug the UPS back, and observe the console for a message that UPS in now ONLINE. If it does not work, try the next driver.
Once you find the working driver, post here so other people do not have to go through the same process with the same UPS model.
If you do not have time for all this, then pick one of the known compatible UPS models.
