Huawei SUN2000-3KTL-M1 User Manual

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.
NO TICE
● Avoid scratching the core wire when stripping a cable.
● The cavity formed after the conductor crimp strip of the OT terminal is crimped
must wrap the core wires completely. The core wires must contact the OT
terminal closely.
● Wrap the wire crimping area with heat shrink tubing or PVC insulation tape.
The heat shrink tubing is used as an example.
● When using a heat gun, protect devices from being scorched.
