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; or
• 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.

Inverter
The icons on the inverter body are as follows.

 Disconnect the inverter from all the external power sources before maintenance!
 Burn danger due to hot surface that may A exceed 60 °C.
 Danger to life due to high voltages! Do not touch live parts for 10 minutes after disconnection from the power sources. Only qualified personnel can open and service the inverter.
 Read the user manual before maintenance!
RCM mark of conformity.
 TUV mark of conformity.
 CE mark of conformity. EU/EEA Importer.
 Do not dispose of the inverter together with household waste.

DANGER
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.
