1 Overvoltage category II (DC input) The device is suitable for connection to PV strings. Long feed cables out of
doors or a lightning protection system in the vicinity of the PV system may make lightning protection or surge
protection equipment necessary.
2 Overvoltage category III (AC output): The device is suitable for permanent connection in the grid distribution
behind the meter and the line protection fuse. When the connection line travels outdoors over long distances,
overvoltage protection devices may be necessary.
Contamination degree 3: Conductive contamination is present. Dry, non-conductive contamination becomes
3
conductive when condensation forms.
In the case of symmetrical DC feed-in, two equally large strings are connected to the inverter. In the case of
4
unsymmetrical DC feed-in, strings of varying lengths are connected to the inverter.
Disconnection device to VDE V 0126-1-1, for Austria: The inverter is equipped "With automatic disconnection
5
device in accordance with ÖVE/ÖNORM E 8001-4-712".
It is essential to ensure that with parallel connection the maximum current load of the DC plugs is not
6
exceeded (max. 30 A). This could result in damage to the device. If the DC string input current is higher than the
maximum plug load (see manufacturer's information), both DC inputs should be used.
