WARNING: It is advised to carefully follow the steps of this procedure in
order to avoid possible damage to property and/or persons and damage to
the equipment. The AURORA inverters have very high operational voltages
which can be extremely dangerous if all precautions are not observed.
WARNING: The following operations must always be carried out when
accessing the interior parts of the inverter in order to avoid injury to people
and damage to property.
STEP 1 If the inverter is connected to the power supply grid, disconnect it by opening
the switch indicated as Part. "D" in Fig. 8
STEP 2 Carefully cover the photovoltaic panels with an opaque material, or perform
the following operations at night. Ensure that the photovoltaic field cannot provide
power before proceeding with the installation.
STEP 3 Disconnect the DC part by opening the integrated disconnect switch (models
