The requirements of the grid operator must be met for grid connection to take place. The permission of the relevant au-
thorities may also be required in order to secure authorisation to connection to the grid.
The enclosed documentation is an integral part of the product. The documentation must be read, observed and stored in
a place which is freely accessible at all times.
The name plate must be permanently attached to the product.
Any other or additional use of the device shall be regarded as improper.
This includes:
ž Use of a distribution system that is not described (grid type)
ž Use of sources other than PV-strings.
ž Mobile use
ž Use in rooms where there is a risk of explosion
ž Use in direct sunlight, rain or a storm or other harsh environmental conditions
ž Outdoor use in environmental conditions that exceed the limits stated in the technical specifications >Environmental
data.

Protection features

The following monitoring and protection functions are built-in:
ž Overvoltage conductor / varistor to protect the power semiconductors from high-energy transients on the grid and
generator sides.
ž Device temperature monitoring system
ž EMC filter to protect the inverter from high-frequency grid interference
ž Grid-side varistors grounded to earth to protect the product against burst and surge pulses
ž Anti-islanding detection according to the current standards.
ž ISO/AFI 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 installa-
tions- 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
overvoltage conductor or, if this is not practicable, then the test voltage can be reduced to 250V.
