• Make sure to read over, fully understand and strictly follow the detailed instructions of the user manual and other related regulations before installing the equipment. The user manual can be downloaded by visiting the website at http://support.sungrowpower.com/; or it can be obtained by scanning the QR code on the side of the equipment or the back cover of this guide.
• All installations must be performed by qualified personnel who should have training for installation and commissioning of electrical system, as well as dealing with hazards, have knowledge of the manual and of the local regulations and directives.
• Before installation, check that the package contents are intact and complete compared to the packing list. Contact SUNGROW or the distributor in case of any damaged or missing components.
• The cable used must be intact and well insulated. Operation personnel must wear proper personal protective equipment (PPE) all the time.
• Any violation could result in personal death or injury or device damage, and will void the warranty.

Safety

The inverter has been designed and tested strictly according to international safety regulations. Read all safety instructions carefully prior to any work and observe them at all times when working on or with the inverter. Incorrect operation or work may cause:

• injury or death to the operator or a third party;
  • damage to the inverter and other properties.

Please follow the safety instructions related to the PV strings and the utility grid.

DANGER

Lethal voltage!

• PV strings will produce electrical power when exposed to sunlight and can cause a lethal voltage and an electric shock.
• Only qualified personnel can perform the wiring of the PV panels.

NOTICE

Danger to life from electric shock due to lethal voltage!

• All electrical connections must be in accordance with local and national standards.
• Only with the permission of the utility grid, the inverter can be connected to the utility grid.

Danger to life from electric shocks due to live voltage

• Do not open the enclosure at any time. Unauthorized opening will void warranty and warranty claims and in most cases terminate the operating license.
• When the enclosure lid is removed, live components can be touched which can result in death or serious injury due to electric shock.

Lethal danger from electric shock due to possibly damaged inverter

- Only operate the inverter when it is technically faultless and in a safe state.

- Operating a damaged inverter can lead to hazardous situations that can result in death or serious injuries due to electric shock.

WARNING

Risk of inverter damage or personal injury

• Do not connect or disconnect the PV and AC connectors when the inverter is running.
• Wait at least 10 minutes for the internal capacitors to discharge after all electric devices are removed and the inverter is powered off.
• Ensure that there is no voltage or current before connecting or disconnecting the PV and AC connectors.

WARNING

All the warning labels and nameplate on the inverter body:

• must be clearly visible; and
• must not be removed, covered or pasted.

CAUTION

Risk of burns due to hot components!

- Do not touch any hot parts (such as the heat sinks) during operation. Only the DC switch can safely be touched at any time.

NOTICE

Only qualified personnel can perform the country setting. Unauthorized alteration may cause a breach of the type-certificate marking.

Risk of inverter damage due to electrostatic discharge (ESD)!

By touching the electronic components, you may damage the inverter. For inverter handling, be sure to:

• avoid any unnecessary touching; and
• wear a grounding wristband before touching any connectors.
