WARNING

Danger to life due to fire and deflagration

In rare cases, an explosive gas mixture can be generated inside the product under fault conditions. In this state, switching operations can cause a fire and, in very rare cases, a deflagration inside the product. Death or lethal injuries due to the spread of a fire can result.

  1. In the event of a fault, do not perform any direct actions on the product.
  2. In the event of a fault, ensure that unauthorized persons have no access to the product.
  3. In case of failure, disconnect the PV module via an external disconnection device. If there is no disconnection device present, wait until no more DC power is applied to the inverter.
  4. In the event of a fault, disconnect the AC circuit breaker, or keep it disconnected in case it has already tripped, and secure it against reconnection.

  • Mounting the inverter in living areas is not permitted.

  • Specialists must have exclusive access to the mounting location.

  • A solid support surface must be available. When mounted on drywall or similar materials, the product emits audible vibrations during operation which could be perceived as annoying.

  • The mounting location must be suitable for the weight and dimensions of the product.

  • The mounting location must not be exposed to direct solar irradiation. If the product is exposed to direct solar irradiation, the exterior plastic parts might age prematurely and overheating might occur. When becoming too hot, the product reduces its power output to avoid overheating.

  • The DC load-break switch of the product must always be freely accessible.

  • All ambient conditions must be met.
