Aurora inverter from the Grid before opening the DC disconnect switch.
WARNING
: To avoid the risk of electric shock from energy stored in
capacitors, wait 5 minutes after disconnecting both AC and DC sides before
opening the front panel.
WARNING
: A requirement, when selecting the electrical cables, is to
carefully evaluate the nominal operating voltage, the insulation rating, the
max operating temperature, the current rating, and the flammability rating in
accordance with the local safety standards.
When selecting the wire for the installation, the correct size needs to be
selected in order to avoid efficiency loses. Refer to Table CN-01 (section
3.3.6) "AC Grid Connections" to select the cable size.
