Disconnecting DC cables

The inverter must first be de-energised on the AC side. Then all DC connections on the inverter can be disconnected. You will need the disassembly tool supplied with the device.

DANGER

danger

Risk of death due to electrical shock and discharge!

When working in the terminal compartment, on the DC supply lines or on the PV modules, the DC cables must still be disconnected.

  1. De-energise all devices and secure them against being switched on again.

  2. INFO

    Info

    PV generators/cables may be live as soon as they are exposed to light.

  3. Disconnect the DC cables by interrupting the connections to the PV modules.
    If it is not possible to disconnect the DC cables, observe the rules for working under voltage:
    - Use personal protective equipment, hard hat, visor or goggles, protective suit, insulating gloves.
    - Use an insulating protective mat as an underlay.
  4. Insert the disassembly tool into the plug's side release openings so that the plug is unlocked and separated from the socket by approx. 1.5 mm.
  6. Remove plug from the socket.
  7. Ensure that the disconnected DC cables are protected against both weather (rain) and unauthorized access.
  8. Check that all connections on the inverter are voltage-free.
  9. Wait at least 10 minutes before carrying out any further work on the inverter so that the capacitors contained in it can discharge.
  1. The inverter is isolated on the DC side and voltage-free.
