MGE UPSes shutdown after 120 seconds when low battery condition is met
(when batteries reach 30% by default) and restart automatically after a
few seconds when the power comes back even if no computer is attached.

The computer connection allows to change the default and to warn the
computer of the mains status to allow for safe shutdown.
