protection is missing
Overvoltages (e. g. in the event of a flash of lightning) can be further
conducted into the building and to other connected devices in the same network
via the network cables or other data cables if there is no surge protection.
Touching live parts and cables results in death or lethal injuries due to
electric shock.
- Ensure that all devices in the same network are integrated in the existing overvoltage protection.
- When laying the network cable outdoors, ensure that there is suitable surge protection at the network cable transition from the product outdoors to the network inside the building.
- The Ethernet interface of the product is classified as “TNV-1” and offers protection against over voltages of up to 1.5 kV.
WARNING
Danger to life due to fire and explosion
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
inside the product or explosion. Death or lethal injuries due to hot or flying
debris can result.
- In the event of a fault, do not perform any direct actions on the product.
- Ensure that unauthorized persons have no access to the product.
- Do not operate the DC load-break switch on the inverter in case of an error.
- Disconnect the PV array from the inverter via an external disconnection device. If there is no disconnecting device present, wait until no more DC power is applied to the inverter.
- Disconnect the AC circuit breaker, or keep it disconnected in case it has already tripped, and secure it against reconnection.

Change to the names and units of grid parameters to comply with the
gridconnection requirements in accordance with Regulation (EU) 2016/631 (valid
from April 27, 2019)
To comply with the EU grid-connection requirements (valid from April 27, 2019)
the names and units of grid parameters were changed. This change is valid from
firmware version 3.00.00.R if a country data set for fulfilling the EU grid-
connection requirements (valid from 2019-04-27) is set. Names and units of
grid parameters for inverters with firmware version 2.99.99.R are not affected
by this change and remain valid. This also applies from firmware version
3.00.00.R if a country data set that is valid for countries outside the EU is
set.
A country data record must be set for feed-in operation
From firmware version 3.11.00.R, the activation conditions for feed-in
operation were changed.
To ensure the inverter begins feed-in operation during initial commissioning,
a country data record must be set (for instance via the installation assistant
on the user interface of the product, or via a communication product).
If no country data record is set, then feed-in operation will be stopped. This
state is signaled by the green and red LEDs flashing simultaneously.
The inverter will automatically start feed-in operation only after the
inverter configuration is completed.
The country data set must be set correctly.
If you select a country data set which is not valid for your country and
purpose, it can cause a disturbance in the PV system and lead to problems with
the grid operator. When selecting the country data set, you must always
observe the locally applicable standards and directives as well as the
properties of the PV system (e.g. PV system size, grid-connection point).
- If you are not sure which standards and directives are valid for your country or purpose, contact the grid operator.
