Operate the device only with a permanent connection to the public power grid. The country and grid type se-
lection must be commensurate with the respective location and grid type.
For the grid connection, the requirements of the grid operator must be implemented. In addition, the autho-
rization for connection to the grid may be subject to approval by the responsible authorities.
The name plate must be permanently attached to the product and must be in legible condition.
For grid connection, the requirements of the grid operator must be implemented. In addition, the authorisation
to connect to the grid may be subject to approval by the responsible authorities.
Any other or additional use is not considered proper or intended use and can lead to an annulment of the prod-
uct guarantee. This includes:
– Use of a distribution system that is not described (grid type)
– Use of sources other than PV-strings.
– Mobile use
– Use in rooms where there is a risk of explosion
– Use in direct sunlight, rain or a storm or other harsh environmental conditions
– Operation outside the specifications prescribed by the manufacturer
– Overvoltage of more than at the DC connection. 1500 V
– Device modification
– Standalone mode

Protection features
The following monitoring and protection functions are integrated in the device:
– RCMU (Residual Current Monitoring Unit)
– Overvoltage conductor/varistor to protect the power semiconductors from high-energy transients on the
grid and generator side
– Device temperature monitoring system
– EMC filters to protect the product from high-frequency grid interference
– Grid-side grounded varistors to protect the product against burst and surge impulses
– Islanding detection (anti-islanding) according to the current standards
– IMI (Isolation Monitoring Interrupter) detection of a generator insulation fault.
NOTE
If the device is connected, the overvoltage conductors / varistors contained in the device have an impact on the
electrical system insulation resistance test as per HD 60364-6 / IEC 60364-6 Low-voltage installations- Part 6:
Verification.
IEC 60364-6 6.4.3.3 describes two options for this case. The first option is to disconnect devices with an over-
voltage conductor or, if this is not practicable, then the test voltage can be reduced to 250V.
