Procedure for Receiving a Replacement Device

Qualified person

Under fault conditions, the product may need to be replaced. If this is the case, you will receive a replacement device from SMA Solar Technology AG. If you received a replacement device, replace the defective product with the replacement device as described below.

  1. To simplify the configuration of the replacement device, save the configuration data of the defective product to a file ( > Saving the Configuration in a File).
  2. Decommission the defective product ( > Decommissioning the Inverter). Remove interfaces and keep them safe for installation into the replacement device (if available).
  3. Mount the replacement device and make the electrical connections as described in this document.
  4. If needed, install interfaces in the replacement device and connect the interfaces (see the interface manual).

  5. DANGER

    Danger to life due to high voltages

    Once disconnected from voltage sources, residual voltages can remain in the product that should be allowed to discharge completely.

    1. Wait 10 minutes before opening the upper enclosure lid.
  6. If the upper enclosure lid of the replacement device is a transport lid (see information on the enclosure lid), replace the transport lid of the replacement device with the upper enclosure lid of the defective inverter.

    • Unscrew all screws of the upper enclosure lid (TX25) and remove it.

    • Position the upper enclosure lid with the six screws and serrated conical spring washers on the enclosure and tighten it in the specified order (TX25, torque: 6 Nm (53 in)).

  7. If the lower enclosure lid of the replacement device is a transport lid (see information on the enclosure lid), replace the transport lid of the replacement device with the lower enclosure lid of the defective inverter.

    • Unscrew all six screws of the lower enclosure lid (TX25) and carefully remove it towards the front. When doing so, note that the LED assembly in the enclosure lid and the communication assembly in the inverter are connected via a ribbon cable.

    • Pull the ribbon cable connecting the LED assembly in the enclosure lid to the communication assembly out of the jack located on the communication assembly.

    • Move the lower enclosure lid to the lower enclosure part. Plug the ribbon cable into the jack on the communication assembly. Ensure that the ribbon cable is firmly plugged into the jacks at both ends.

    • Tighten all six screws of the lower enclosure lid crosswise (TX25, torque: 3 Nm ± 0.3 Nm).

  8. Commission the replacement device ( > Commissioning the Inverter).
  9. Establish a connection to the user interface ( > Establishing a connection to the user interface).
  10. Configure the inverter using the installation assistant.
  11. To reuse the saved configuration data of the defective inverter, load it from the respective file ( > Adopting a Configuration from a File).
  12. If the defective inverter had been registered by a communication product, replace it with the new product in the communication product.
  13. Pack the defective product in the packaging of the replacement device and arrange with SMA Solar Technology AG for it to be picked up.
