I'd ideally set it to "shut down when only 20% battery left" (which

Could someone please point me to where (or what for) to look to
configure that? Or is it not necessary? Or is my UPS not capable of
triggering based on power left and I must use a time based setup (sleep

Hi, The UPS doesn't report its battery charge, but since the DB-9 pinouts
described in the User Guide, page 11 include a "Low Battery Alarm" you may
be able to get enough from this to avoid a timer-based shutdown.
You will probably need to do some experiments (without risking your
server) to see what signals are received from the battery as it runs down
to empty. For that you will need a suitable upsmon.conf with at least a
NOTIFYFLAG LOWBATT SYSLOG+WALL
NOTIFYFLAG ONBATT SYSLOG+WALL
NOTIFYFLAG ONLINE SYSLOG+WALL
