Device replacement

Replace the device as follows:

  1. Consider the safety notes in chapter Creating a safe working environment.
    • Make sure the device is de-energized. The 400 V line voltage and the 24 V backup voltage must be disconnected.
  2. When you replace the device including the electronics cover, you also have to carry out the steps described in chapter "Replacing the electronics cover".
  3. Remove the device. Observe the removal notes in chapter "Mechanical installation".
  4. Compare the data on the nameplate of the old device with the nameplate data of the new device.

    5. INFORMATION

    Always replace the decentralized inverter with a decentralized inverter that has the same properties.
    In safety-related applications, replace a decentralized inverter only with a decentralized inverter with the same FS logo.
  5. Install the device. Observe chapter "Mechanical installation".
  6. Perform the installation according to chapter "Electrical installation".
  7. Remove the memory module from the old electronics cover. Insert this memory module in the new electronics cover.
  8. Place the electronics cover onto the connection box and screw it in place.
