1. Please immediately disconnect the
leakage/over current protection switch from
the distribution box.
2. Please check whether the input/output
line of the AV charger is properly grounded
or not.
3. After troubleshooting the issues
mentioned above, please attempt to power
on the system again. If the problem persists,
please contact us for further assistance.
1. If the voltage drops below 190Vac for
level 2 or 90Vac for level 1 for a brief period
of time, the charger will go into standby
mode and check the power network to
restore itself to the normal voltage range.
Once the voltage is within normal range,
the charger will automatically resume
charging.
2. If the voltage in your area/community
remains consistently low (below 190Vac for
level 2 or 90Vac for level 1) for an extended
period of time, please wait to use the
charger until the voltage recovers back to
the normal range.
