● Wear personal protective equipment and use dedicated insulated tools to avoid
electric shocks or short circuits.
NO TICE
● Before turning on the AC switch between the inverter and the power grid,
check that the AC voltage is within the specied range using a multimeter.
● If the DC power supply is connected but the AC power supply is disconnected,
the inverter will report a Grid Loss alarm. The inverter can start properly only
after the power grid recovers.
Procedure
Step 1 Turn on the AC switch between the inverter and the power grid.
Step 2 (Optional) Remove the locking screw next to the DC SWITCH.
