Procedure
Step 1 Turn on the AC switch between the SUN2000 and the power grid.
If you perform Step 3 before Step 1, the SUN2000 reports a fault about abnormal
shutdown. You can start the SUN2000 only after the fault is automatically
rectied.
Step 2 (Optional) Remove the screws that secure DC SWITCH 1, DC SWITCH 2, and DC
SWITCH 3. Store the screws properly for future power-o maintenance.
For the model used in Australia, perform this step based on the local standards.
