When working on the DC feed cables

DANGER

danger

Risk of death due to electrical shock and discharge

During operation, high voltages are present on the live parts and cables inside the product. Touching live parts or cables will result in death or life-threatening injuries from electrical shock.

When working on the DC feed cables, the inverter must be made completely voltage-free and the DC feed cable must be removed.

Perform these steps to do so:

  1. Turn the DC switch on the inverter to OFF.
  2. If used, switch off the power supply for the self-consumption output.
  3. If used, switch off the power supply for the switched outputs.
  4. If external DC voltage separators are present, switch off the DC strings consecutively.
  5. If a battery is connected, switch off the battery storage. A detailed description of how to switch off the battery storage is available in the operating manual provided by the battery manufacturer.
  6. Switch off the AC line circuit breaker.
  7. Secure the entire voltage supply against being restarted.
  8. Disconnect all DC connections on the inverter. To do this, unlock the engaging clips with a screwdriver and disconnect the plug.

  11. Ensure that all connections are voltage-free.
  1. The inverter is now completely voltage-free.

Work on the inverter can now be carried out.

Use insulated tools when working on the DC feed cables because they may be live.
