2. When selecting the installation site, you should ensure that there is no interference from any other power electronic equipment in the surrounding area.

3. Before you making electrical connections, please use opaque material covered the PV panel or disconnected the DC-side circuit breaker. Photovoltaic arrays will produce dangerous voltages if them are exposure to sunlight.

4. All installation operations must be done only by professional technicians.

5. The cables used in the PV system must be securely connected, well insulated, and properly sized.

6. All electrical installations must meet local and national electrical standards.

7. The inverter ca be connected after the local power sector has been approved and all electrical connections have been made by a professional technician.

8. Before performing any maintenance work, first you need disconnect the connection between inverter and electrical grid, then disconnect the DC side electrical connection.

9. Wait at least 5 minutes until the internal components are discharged, then you can repair the inverter.

10. Before turning on the inverter again, any machine failure that can affects the inverter safety must be immediately removed .

11. Avoid unnecessary board contact.

12. Observe the static protection standard, wear anti-static bracelet.

13. Watch and follow the warning signs on the product.

14. Perform a preliminary visual inspection of the equipment for damage or other dangerous conditions.

15. Attention the inverter hot surface, such as power semiconductor heat sink. Because the inverter still maintain a high temperature after it is power off.

Position Requirements of Inverter Installation

1. Do not install the inverter in direct sunlight position. Otherwise it may cause additional internal temperature, even the temperature is too high lead to inverter temperature failure.

2. Select a installation site should be strong enough to support the weight of the inverter for a long time.

3. The installation site should at an ambient temperature between -25 ° C to 50 ° C, the installation environment should be clean.

4. The environment humidity of installation site should be below 95%, and no condensation.

5. There should be enough clearance in front of the inverter to make it easy to observe data and repair.

6. Install the inverter as far as away from the residents, because its operation will produce some noise.

7. Installation place should be stable, can not be shake.
