    The device is intended for indoor and outdoor applications and may only be used in countries for which it has been ap- proved or for which it has been released by KACO new energy and the grid operator. Operate the device only with a permanent connection to the public power grid. The country and grid type selection must be commensurate with the respective location and grid type.

  • Page 10 In addition to the safety functions, the internal interface switches can also be actuated via the "Inverter Off" input. If a Powador-protect is used as the central interface protection, the fail-safe disconnection of suitable KACO inverters from the public grid can be carried out by the internal interface switches instead of separate interface switches. This re- quires the inverters in the photovoltaic system to be connected to the Powador-protect.

    – Close to the ground, accessible from the front and sides without requiring additional resources. – In outdoor areas, KACO new energy recommends protecting the device from direct weather exposure and sunlight. This should be carried out by means of constructional measures (e.g. wind breaks) in order to reduce thermal heating of the components, premature derating and more extensive wear of the fans.

    Some grid connection rules insist that the agreed reactive power be supplied from every operating point of the plant without a reduction in the actual active power. Because KACO devices have the full P-Q operating range, a reduction in the active power is, however, required during operation at maximum active power because an apparent power reserve is not available.
