1.4.3 Safety instructions for installation
▪Fire hazard in event of improper use !
−Never install the solar inverter in an explosive and/or
unventilated area. Pay attention to the observance of the
specified temperature range for the environment .
− Ensure the necessary air circulation .
− The solar inverter must not be positioned near sources of heat .
− Always note the operating position during the installation.

▪Maintain the necessary minimum distance to neighboring equipment or
walls for the purpose of ventilation.
▪Risk of injury from electric arcs!
−Never install or operate the device in a damp environment.
−As a rule, keep liquids away from the device.
−After installing the device, condensation effects can occur as a result of
great temperature differences. That is why an acclimation period of at
least 2 hours should be maintained before further steps can be
undertaken. Make sure that the temperature compensation is
concluded and that the interior and exterior condensed areas have
dried completely.
▪Risk of accident from improperly executed installation work!
−Do not stand on the device!
−Install the solar inverter in an easily accessible location.
−Place the cable so that it cannot be stepped on or tripped over.
−The electrical connection must be carried out in accordance with
the wiring diagram by an authorized electrician as per VDE and the
current EVM regulations!
−In normal operation, the device must not be operated with a dismantled cover!

1.4.4 Safety instructions for operation
▪Danger from suddenly occurring disturbances!
− Report the occurrence of disturbances immediately to the responsible
person!
▪Risk of injury from connected power sources (battery feed)!
−The output terminals are energized by the battery feed in the event of of a
failure of the on-site power supply (e.g. power outage)!
−In normal operation, the device must not be operated with a dismantled cover!
The solar inverter should not be disconnected from the on-site energy supply
when properly operated (normal operation) The batteries cannot be charged if
the power supply is disconnected. The solar inverter can only function properly
with charged batteries.

1.4.5 Safety instructions for maintenance and repairs
▪High and low voltage: risk of injury!
−The battery circuit is not disconnected from the input voltage.
Hazardous voltages can occur between the battery poles and
the ground. Confirm that voltage is not present before touching!
−Before commencing with maintenance or repair work on the device, you
must
disconnect the device from the supply network and the battery feed.
▪Residual energy: risk of injury!
−Even after the device has been disconnected from the power
supply, the components of the solar inverter are still energized
(battery feed!) and are dangerous!
−Before performing maintenance and/or service work, disconnect the
batteries from the power supply and ensure that there is no electricity
and no dangerous voltage on the terminals of high-performance
condensers, such as e.g. BUS condensers!
▪Improper repair work: risk of injury!
−Improper repair work can lead to unexpected behavior of the solar
inverter! This can cause injury to persons.

− You can only use isolated tools in accordance with IEC 60900!
− Wrist watches, jewelry and other metal objects must be removed!
− Maintenance and repairs can only be performed by trained specialists.
−Only persons who are sufficiently familiar with batteries and the necessary
safety measures are permitted to switch batteries and monitor the operation.
Unauthorized persons must be kept away from the batteries.
−Always install the same number and the same battery type when
replacing the battery.
− Replace the fuse only with one of the same type and current strength!
▪Accumulators and their connections can cause electrical shock. Risk of injury !
−If there are short circuits on the accumulators, touching the current-
bearing parts can cause severe burns .
−Accumulators should never be linked to heat sources and must not
be near flames. There is a risk of explosion !
1.4.6 Safety instructions for disposal
▪High and low voltage: risk of injury !
− Batteries can cause electrical shock and high short-circuit currents .
− Do not touch the electrical components !
