7.1 Powering On the SUN2000
● Wear personal protective equipment and use dedicated insulated tools to avoid
electric shocks or short circuits.
When the grid connection indicator is steady green (the SUN2000 is connected to
the power grid), do not turn on the DC switch. Otherwise, the SUN2000 may be
damaged because insulation resistance detection is not performed.
