Powering On the System

NOTICE
Before turning on the AC switch between the inverter and the power grid, use a multimeter to check
that the AC voltage is within the specified range.
1. Turn on the AC switch between the inverter and the power grid.
2. Ensure that the DC switches at the inverter bottom are ON.
3. (Optional) Measure the temperatures at the joints between the DC terminals and the connectors
using a point-test thermometer.
NOTE
To check that the DC terminals are in good contact, check that the temperatures at the joints
between DC terminals and connectors do not exceed 85 ° C after the inverter has been running for
a period of time.
4. Observe the indicators to check the inverter operating status.
