NO TE
● The minimum cable diameter should comply with the local cable standard.
● Factors influencing cable selection are as follows: rated current, type of cable, routing
method, ambient temperature, and maximum desired line losses.
5.2 Connecting the PE cable
Important Notes
D ANGER
● Ensure that the PE cable is securely connected. Otherwise, electric shocks may
occur.
● Do not connect the N 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 point, not a
substitute for the PE point on the enclosure.
● It is recommended that silica gel or paint be applied around the ground terminal after
the PE cable is connected.
Supplementary Notes
The SUN2000 has the grounding detection function. This function is used to check
whether the SUN2000 is properly grounded before the SUN2000 starts, or check
