5.5 Second Protective Earth Connection
DANGER !
Do not connect the neutral wire to the enclosure as a PE cable.Otherwise,
electric shocks could occur.
CAUTION
The PE point at the AC output port is used only as a PE equipotential
point, and cannot substitute for the PE point on the enclosure.
There is a protective grounding hole at the bottom of the inverter. The user must make
the inverter grounded through the grounding hole and tighten it with M4*8 screws (As
shown in the figure below).
5.7 Connection of Anti-Backflow Meter (Optional)
The inverter equipped with anti-backflow function can perform power regulation and
prevent feeding energy into the grid. Before using the anti-backflow function, the user
should read the instructions carefully and correctly connect the cables as shown in the
figure.Connection error may lead to unpredictable consequences, contact the
maintenance personnel in this case.
