 Wiring
 The wiring must be conducted by qualified electricians. Otherwise, electric shock may
happen or inverter may be damaged.
 Before wiring, confirm that the power supply is disconnected. Otherwise, electric shock
may happen or fire.
 The PE terminal must be grounded firmly; otherwise, the inverter enclosure may
become live.
Please do not touch the main circuit terminals. The wires of the main circuit terminals

must not contact the inverter enclosure. Otherwise, electric shock may happen.
The connecting terminals for the braking resistor are

connect terminals other than these two. Otherwise, fire may be caused.
 The leakage current of the inverter system is more than 3.5mA, and the actual value of
the leakage current is determined by the operation application conditions.Inverter and
the motor must be grounded firmly to ensure the safety.
 Wiring
 The three−phase power supply cannot connect to output terminals UTTT, VTTT and
WTT3; otherwise, the inverter will be damaged.
 It is forbidden to connect the inverter output terminals to the capacitor or LCTRC noise
filter with phase lead, otherwise, the internal components of the inverter may be
damaged.
 Please confirm that the power supply phases and rated input voltage are consistent with
those indicated by the nameplate, otherwise, the inverter may be damaged.
 Do not perform dielectric strength test on the inverter, otherwise, the inverter may be
damaged.
 The wires of the main circuit terminals and the wires of the control circuit terminals shall
be laid separately or in a square−crossing mode, otherwise, the control signal may be
interfered.
 The wires of the main circuit terminals should adopt lugs with insulating sleeves.
 The sectional area of input and output cables should be selected according to the
inverter power.
 When the cables between the inverter and the motor are longer than T00m, it is
suggested to use output reactor to avoid the over current fault caused by the distribution
capacitor.
 If the inverter equipped with a DC reactor, DC reactor must be connected between the
terminals of ○ T and ○ T, otherwise the inverter will not display after power on.
