[c-nsp] Problem w/ ASR1001

[Виктор Моисеев (ПГУ)]

Just observations...
We once got an asr1004 that worked on 190v input power.
(psu was rated 230v input).
It worked in this conditions for about 2 months until we get new feeders to
location.
Of course it generated alarms, but worked with no issues.
