Nut upsuser - Dec 2014 - Do I need to configure times and percents?

On Debian Linux jessie:

After buying an UPS and installation of nut-server and nut-client at my PC and
configuring the ports and the protocol, do I need to adjust time and/or
percentage parameters, to be sure my computer will be turned off automatically
after a reasonable time after failing electricity?

My UPS is Advice PRS850.

If I need to adjust the parameters, please explain the details.

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.
