Version-Release number of selected component (if applicable):

Very

Steps to Reproduce:
1. Adjust time or %bat to a convenient (small) value in /etc/apc/apcupsd.conf
2. Issue 'systemctl restart apcupsd.service'
2. Unplug UPS from mains
3. Wait a bit...

Systems fans are still spinning, etc.

Additional info:
This was a fresh install of apcupsd. No config changes.

I see one error in the events log.

This does not look like a simple permissions problem.
$ stat -c '%A %U %G %n' /etc /etc/apcupsd/ /etc/apcupsd/*
drwxr-xr-x root root /etc
drwxr-xr-x root root /etc/apcupsd/
-rwxr-xr-x root root /etc/apcupsd/apccontrol
-rw-r--r-- root root /etc/apcupsd/apcupsd.conf

-rwxr--r-- root root /etc/apcupsd/commok
-rwxr--r-- root root /etc/apcupsd/offbattery
-rwxr--r-- root root /etc/apcupsd/onbattery

But without that file, the UPS will never be commanded off.
[root@feynman usr]# cat /lib/systemd/system-shutdown/apcupsd_shutdown
#!/bin/sh

# See if this is a powerfail situation.
if [ -f /etc/apcupsd/powerfail ]; then
  echo
  echo "APCUPSD will now power off the UPS"
  echo
  /etc/apcupsd/apccontrol killpower
