There is a risk of inverter damage or personnel injury due to incorrect service
work!
Always keep in mind that inverter is power supplied by dual power source: PV
arrays and utility grid.
Before any service work, you should obey the following procedures.
z
Disconnect inverter from the utility grid side first and then PV arrays;
z
Wait at least ten minutes for inner capacitors discharge completely;
z
Verify that no voltage and current present with appropriate testing device.
Keep non-related person away!
A temporary warning sign and barrier must be posted to keep non-related
person away for any period while performing electrical connection and service
work.
Do not open the enclosure when the inverter is under voltage. There is a highly
unlikely risk of explosion in very specific cases of malfunction. The housing will protect
persons and property from such an explosion, only if it is correctly sealed.
There is a risk of inverter damage if it is improperly serviced.
Use only accessories and spare parts approved by the inverter manufacturer.
And never modify the inverter or other components of the inverter. Otherwise it
will lead to loss of any and all warranty rights.
There is a risk of inverter damage due to electrostatic discharge!
The printed circuit boards contain components sensitive to electrostatic
discharge. Wear a grounding wrist band when handling the boards. Do not
touch the boards unnecessarily during replacement.
