I'm confused here - the Bash script, and the systemd service unit, are for 
_shutting down_ the system on power failure, but in the trace you are 
having a problem _starting_ the driver.

I havn't tested with openSUSE 13.2 so there may be something in it which 
prevents the driver from connecting to the UPS.  Perhaps with a more 
detailed trace using the upsdrvctl -D option it may be possible to see 
more clearly.
