Lift the inverter, hang the back rail on the fixed wall bracket carefully. Screws the inverter to
the L-shaped plate (The lock is purchased separately). See Figure 4-8 for details:

※ 4.3 External ground connection
Ground terminal connection steps:
① The external grounding terminal is located in the lower right side of the inverter.
② Fix the grounding terminal to the PE wire with a proper tool and lock the grounding
terminal to the grounding hole in the lower right side of the inverter, as shown in Figure
4-9.
③ The cross-sectional area of the external grounding cable is 4mm
2
.
Danger
Do not connect the N-wire as a protective ground wire to the inverter casing. Otherwise,
it may cause electric shock.
Attention
Good grounding is good for resisting surge voltage shock and improving EMI
performance. Inverters must be well-grounded.
For a system with only one inverter, the PE cable needs to be grounded.
For a multi-inverter system, all inverters PE wires need to be connected to the same
grounding copper bar to ensure equipotential bonding.
