DangerDanger
zThe wiring must be conducted by qualified electricians. Otherwise, electric shock may
happen or driver damage.
zBefore wiring, confirm that the power supply is disconnected. Otherwise, electric shock
may happen or fire.
zThe PE terminal must be reliably grounded, and should use the third grounding method
for grounding the PMSM motor at equal voltage potential, otherwise, the driver
enclosure may become live.
zPlease do not touch the main circuit terminals. The wires of the main circuit terminals
must not contact the driver enclosure. Otherwise, electric shock may happen.
zThe connecting terminals for the braking resistor are ⊕2/B1 and B2. Please do not
connect terminals other than these two. Otherwise, fire may be caused.
zThe leakage current of the driver system is more than 3.5mA, and the specific value of
the leakage current is determined by the operationapplication conditions. The driver and
the motor must be grounded to ensure the safety. Suitable leakage current protection
device shall be used if a RCCB is used to avoid unnecessary tripping. Do not connect
the PE of the driver to the N line otherwise electric shock may happen or the driver may
be damaged.
Wiring
NoteNote
zThe three-phase power supply cannot connect to output terminals U/T1, V/T2 and
W/T3, otherwise, the driver will be damaged.
zIt is forbidden to connect the driver output terminals to the capacitor or LC/RC noise filter
with phase lead, otherwise, the internal components of the driver may be damaged.
zPlease confirm that the power supply phases, rated voltage are consistent with those
indicated by the nameplate, otherwise, the driver may be damaged.
zDo not perform dielectric strength test on the driver, otherwise, the driver may be
damaged.
zThe 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.
zThe wires of the main circuit terminals shall adopt lugs with insulating sleeves.
zThe sectional area of driver input and output cables should be selected according to the
driver power. With the shielding layer and the pressure resistant 1000V cables.
zWhen the cables between the driver and the motor are longer than 100m, it is
suggested to use output reactor to avoid the driver failure caused by the overcurrent of
the distribution capacitor.
zFor the application with big voltage fluctuation, an input reactor should be installed; For
the application with strict EMC requirement, an input filter and input inductor with input
impedance higher than 3.5% and DC reactor should be equipped.
zThe driver equipped with a DC reactor must be connected with a DC reactor between
the terminals of ○
+1 and ○
+2, otherwise the driver will not display after power on.
