Photovoltaic generator
Ensure that the insulation of the solar generator has been checked according to
manufacturer’s instructions. The solar generator must be disconnected from the inverter
during the insulation check.
Checking the compatibility with IT (ungrounded) systems
The EMC filter (option +E216) is not suitable for use in an IT (ungrounded) system. Check
that the low-voltage network is of the TN (grounded) type. If not, please contact ABB.
WARNING! If the optional EMC filter +E216 is installed on an IT system (an
ungrounded power system or a high resistance-grounded [over 30 ohm] power
system, the system will be connected to earth potential through the EMC filter
capacitors. This may cause danger or damage the equipment in the network.
Connecting the power cables

1) Solar array junction box
2) 360 degrees grounding is recommended at the cabinet entry if shielded cable is used. Ground the other
end of the input cable shield or PE conductor at the transformer.
3), 4) If shielded cable is used (not required but recommended) and the conductivity of the shield is < 50% of
the conductivity of the phase conductor, use a separate PE cable (3) or a cable with a grounding
conductor (4).
