NO TICE
● Before turning on the AC switch between the SUN2000 and the power grid, use
a multimeter set to the AC position to check that the AC voltage is within the
specified range.
● When the handle of the DC switch points to the
icon, the spring of the
DC switch is in released state and the switch is not completely connected. In
this case, automatic disconnection may fail. You need to set the DC switch to
the ON position.
● When the system is powered on or running, do not place obstacles (such as
cables) to block the rotation of the handle or manually hold the handle.
Otherwise, the DC switch cannot be automatically disconnected.
● If the solar inverter has been stored for more than two years, it must be
checked and tested by professionals before being put into use.
Procedure
Step 1 Turn on the AC switch between the SUN2000 and the power grid.
NO TICE
If you perform
before
, the SUN2000 reports a fault about abnormal
shutdown. You can start the SUN2000 only after the fault is automatically
rectified.
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-off maintenance.
NO TE
For the model used in Australia, perform this step based on the local standards.
Figure 6-1 Remove the screws
Step 3 Set DC SWITCH 1 (MAIN SWITCH) at the bottom of the solar inverter chassis to
ON.When you hear a click sound, the switch is ON.
Step 4 Check the status of the PV connection indicator. If it is steady green, set DC
SWITCH 2 and DC SWITCH 3 to ON.
