I would recommend testing with a dummy load to see if the UPS operates as you expect it to.

In particular, there is no standard for a "reasonable time" for shutdown. In the default configuration, NUT's upsmon program shuts the system down after the UPS reports a low battery. Your UPS may or may not allow that threshold to be configured, so there are several other options if you want to shut down after a specific time on battery, or when other conditions are reached.

You may want to check the list archives to see if anyone else has additional information on other UPS models from this manufacturer:

It actually isn't on our hardware compatibility list:

If you post additional details (output of upsc and upsrw) someone may be able to offer more specific suggestions.
