a shield" on the website.
ATTENTION!
The regulator will protect the load even in the event of regular
phase-to-zero short circuits or poor contact in the neutral wire. (if
at the same time the voltage is above 350V it will switch it off),
but these are emergencies, you still can't work in such conditions.
It is necessary to stop work immediately and to provide repair of
the grid, despite the fact that the regulator functions normally and
provides loading with safe nomilnal voltage.
REMEMBER!
If the mains voltage is above 290V for a long time, it is most likely
a dangerous emergency situation that must be rectified imme-
diately (there may already be a fire on the line or a dangerous
current flow or a live neutral wire). The regulator can operate nor-
mally and provide load, but the grid will not be able to be in an
emergency for a long time and the supply of voltage may stop
sooner or later.
WARNING!
If the regulator input circuit breaker trips out, the regulator proba-
bly has a reason. Try to find out the reason for this disconnection
(closure in load, neutral wire disruption, phase to ground fault in
the power supply grid, other reasons). Do not rush to turn on the
Transit mode - you can deliver emergency voltage directly from
your grid to the load. In Transit mode, the regulator can not pro-
vide complete protection of your load, but only at the level of 530V
(~ 380V ef.), which can be dangerous for many electronic devic-
es. If the input circuit breaker trips out even in the Transit mode, it
is possible that the accident is serious and it is necessary to stop
work immediately and investigate the reasons for the shutdown.
QUANT regulators are very reliable, therefore malfunction of
the regulator itself is rarely the reason of such shutdowns.
