Danger to life due to electric shock when live cables are touched

High voltages are present on the AC and DC cables. Touching live cables results in death or lethal injuries due to electric shock.

  1. Do not touch non-insulated parts or cables.
  2. Disconnect the AC circuit breaker and secure it against reconnection.
  3. Disconnect the PV array from the inverter via an external DC load-break switch (e.g. via a PV junction including a load-break switch). Switch off and secure the DC load-break switch against reconnection.
  4. Ensure that all cables to be connected are de-energized.
  5. Wear suitable personal protective equipment for all work on the product.
