Huawei SUN2000-3KTL-M1 Series User Manual

5.3 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
whether the SUN2000 ground cable is disconnected when the SUN2000 is
running. This function is used to check whether the SUN2000 is properly grounded
under limited conditions. To ensure the safe operation of the SUN2000, properly
ground the SUN2000 according to the connection requirements of the ground
cable. For some power grid types, if the output side of the SUN2000 is connected
to an isolation transformer, ensure that the SUN2000 is properly grounded and set
Isolation to Input ungrounded, with TF to enable the SUN2000 to run properly.
● According to IEC 62109, to ensure the safe operation of the SUN2000 in the
case of ground cable damage or disconnection, properly connect the ground
cable of the SUN2000 and ensure that it meets at least one of the following
requirements before the grounding detection function becomes invalid.
– The ground cable is a single-core outdoor copper cable with a conductor
cross-sectional area greater than or equal to 10 mm
2
.
– Use cables with the same diameter as the AC output power cable and
ground the PE terminal on the AC connector and the ground screw on
the chassis.
● In some countries and regions, the SUN2000 must have additional ground
cables. Use cables with the same diameter as the AC output power cable and
ground the PE terminal on the AC connector and the ground screw on the
chassis.
Procedure
Step 1 Crimp OT terminals.
