Please reduce the number of
electric equipments or check
carefully loads connection.

When load current reaches1.02-1.05 times 1.05-1.25 times, 1.25-1.35
times and 1.35-1.5 times more than nominal value, controller will
automatically turn off loads in 50s, 30s,10s and 2s respectively.
5.3 Maintenance
The following inspections and maintenance tasks are recommended at least
two times per year for best controller performance.

Make sure controller firmly installed in a clean and dry ambient.

