Safety Instructions

Failure to observe safety instructions can result in death, serious injury, or property damage. Key safety measures include:

• Ground Faults: Disconnect the product from all voltage sources and ensure it cannot be reconnected before working on the device. Wait 5 minutes after disconnecting before touching any parts.
• Electrical Safety: Do not touch non-insulated parts or cables. Use only measuring devices with measurement ranges designed for the maximum AC and DC voltage of the inverter.
• Handling: Transport and lift the product carefully, taking its weight into account. Use provided carrying handles or a hoist.
• Environment: Only open the product if the ambient temperature is not below -5°C (23°F) and the environment is free of sand and dust.

Installation

The installation process must be performed by qualified persons. Ensure the mounting location is suitable for the product's weight and environmental requirements (IP65, outdoor use).

• Scope of Delivery: Verify all components are present before starting.
• Mounting: Follow the graphical instructions for mounting the inverter. Ensure the unit is mounted securely.

Electrical Connections

All electrical connections must be made according to local standards and the specifications in this manual.

• AC Connection: Ensure the AC circuit breaker is disconnected and secured. Follow the torque specifications for live bolted connections.
• DC Connection: Install an external DC load-break switch between the inverter and the PV array. Ensure PV modules are compatible and of protection class II.
• Network Connection: Connect the network cable to the Ethernet interface. Ensure suitable surge protection is used for outdoor cable runs.

Commissioning and Configuration

Once installation is complete, proceed with commissioning:

1. Ensure all connections are secure and the enclosure is closed.
2. Switch on the AC circuit breaker.
3. Access the user interface via the network connection (IP address or URL provided in the manual).
4. Configure the country data set correctly to avoid grid operator issues.
5. Set the installer password and complete the system registration.
