Note a: The minimum cross-sectional area should be determined based on the
rated value of the AC fuse.
NO TE
● The minimum cable cross-sectional area must meet local standards.
● The factors to be considered in cable selection include the rated current, cable type,
routing mode, ambient temperature, and maximum acceptable line loss.
5.3 Connecting a PE Cable
Precautions
D ANGER
● Ensure that the PE cable is securely connected. Otherwise, electric shocks may
occur.
● Do not connect the neutral wire to the enclosure as a PE cable. Otherwise,
electric shocks may occur.
NO TE
● The PE point at the AC output port is used only as a PE equipotential bonding point,
and cannot substitute for the PE point on the enclosure.
● It is recommended that silicone grease or paint be applied around the ground terminal
after the PE cable is connected.
● When the phase wire is short-circuited to the PE point, you can set the phase-to-PE
protection switch on the app (choose Settings > Feature parameters > Grounding
Exception Detection). If the switch is disabled, only inverter alarm detection is
performed, and the inverter can connect to the power grid and generate power
normally.
Additional Information
The inverter provides the grounding detection function. This function is used to
check whether the inverter is properly grounded before the inverter starts, or
check whether the ground cable is disconnected when the inverter is running. This
function is only available under limited conditions. To ensure the safe operation of
the inverter, properly ground the inverter according to the connection
requirements of the PE cable. For some power grid types, if the output side of the
inverter is connected to an isolation transformer, ensure that the inverter is
properly grounded and then set Grounding Exception Detection to Disable so
that the inverter can run properly.
● According to IEC 62109, to ensure the safe operation of the inverter in the
case of PE cable damage or disconnection, properly connect the PE cable of
