6.2 System Power-On

Prerequisites
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 allowed range.
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 from the DC switch.
