associated to the inverter.
High voltages may still be present even after disconnecting the power supply.
To prevent electric shock, wait at least ten minutes after turning off the input
power for the complete discharge of the power capacitors. Always connect the
equipment frame to the protective ground (PE). Use the adequate connection
terminal at the inverter.

The electronic boards have electrostatic discharge sensitive components.
Do not touch the components or connectors directly. If necessary, first touch the
grounded metallic frame or wear a ground strap.
