● The specications are valid only if the conductors of the PE cable and AC power cable use the
same material. If the materials are dierent, ensure that the conductor cross-sectional area of
the PE cable produces a conductance equivalent to that of the cable specied in the table.
● The specications of the PE cable are subject to this table or calculated according to IEC
60364-5-54.
5.3 Installing the PE Cable
Context
NO TICE
● Proper grounding is helpful for resisting the impact of surge voltage and
improving the electromagnetic interference (EMI) performance. Before
connecting the AC power cable, DC power cable, and communications cable,
connect the PE cable to the PE point.
● It is recommended that the PE cable of the SUN2000 be connected to a nearby
PE point. Connect the PE points of all SUN2000s in the same array to ensure
equipotential connections to PE cables.
Procedure
Step 1 Connect the PE cable to the PE point.
