There is a risk of inverter damage or personal injury due to incorrect service
work!
Always keep in mind that the inverter is power supplied by dual power
source: PV arrays and utility grid.
Before any service work, observe the following procedures.
Disconnect the inverter from the utility grid side first and then PV arrays;
Wait at least 10 minutes for inner capacitors to discharge completely;
Verify that no voltage and current existing with appropriate testing
devices.
Keep non-related persons away!
A temporary warning sign or barrier must be posted to keep non-related
persons away while performing electrical connection and service work.
Do not open the enclosure when the inverter is under voltage. There is a high likely
risk of explosion in very specific cases of malfunction. The enclosure 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 accessories and spare parts approved by the inverter manufacturer
only. Never modify the inverter or other components of the inverter. The
loss of any or all warranty rights may follow if otherwise.
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. Avoid
unnecessary touch of the boards during replacement.
