Note:
Make sure PV wires from solar panels are connected to the inverter with the correct polarity.
The inverter does not suffer any damage, but it will not generate power until the polarity is
corrected. The max. input voltage, as defined in the specifications, shall be higher than the
Standard Test Condition (STC) open circuit voltage for the PV modules / array multiplied with
a factor of 1.13. Please observe that thin film modules may produce a higher voltage and
current output before initial degradation, and ensure U
this case.

The screws on the front cover are defined as Torx 30 and must be unfastened (1).
Pull cover away from the lower part of the inverter (2).
Make sure to unplug the display cable before removing the front cover completely (2).
Slide and lift upwards to unhook the cover (3).
The front cover must be hooked on to the hinges at the top and pushed in place.
Apply torque 3.5 Nm to the screws
Remember to reconnect the display cable.
Fasten the front screws to ensure proper PE connection.
The two front screws are the PE connection to the front cover. Make sure that both
are mounted and fastened with the specified torque.
Make sure the PV module open circuit voltage never exceeds the specified maximum
input voltage of the inverter. Check the specification of the open circuit voltage at
the lowest PV module operating temperature.
The MC4 connectors are not IP54. The intrusion of moisture may occur in the fol-
lowing situations:
1. The inverter runs in Master/Slave operation and only one PV input is being
used. In this case, the other 1-2 inputs are not connected to PV and they
are therefore open to intrusion.
2. Not all PV inputs are connected.
3. PV connectors are not fitted; for example in case of disconnection of parts
of a PV plant over a longer period of time.
In situations where the PV connectors are not fitted, a seal cap must be mounted
(included in the scope of the delivery).
