[Nut-upsuser] APC CS650 not turning load back on when power return

Hi all,

I'm in the process of testing a new APC Back Ups CS-650, connected to a
Debian Linux box via USB and being monitored with NUT v2.4 (installed via
the package from Debian testing).

When I remove power from the UPS (with a dummy load connected) then once the
battery gets down to the appropriate level the PC it's connected to via USB
shuts down, and tells the UPS to power down the load, which it does.

However, if I then re-apply power to the UPS, the load is never switched
back on. Is this supposed to happen automatically, or do I have something
misconfigured? Is this behaviour typical for this model of UPS, or does it
indicate a problem?

Thanks for any advice you can offer.
