Safety Precautions
Wiring
DangerDanger
The wiring must be conducted by qualified electricians. Otherwise, electric shock may
happen or controller damage.
Before wiring, confirm that the power supply is disconnected. Otherwise, electric shock
may happen or fire.
The PE terminal must be reliably grounded , otherwise, the controller enclosure may
become live.
Please do not touch the main circuit terminals. The wires of the main circuit terminals
must not contact the controller enclosure. Otherwise, electric shock may happen.
The 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.
The leakage current of the controller system is more than 3.5mA, and the specific value
of the leakage current is determined by the operation application conditions. The
controller and the motor must be grounded to ensure the safety.
Wiring
NoteNote
The three-phase power supply cannot connect to output terminals U/T1, V/T2 and W/T3,
otherwise, the controller will be damaged.
It is forbidden to connect the controller output terminals to the capacitor or LC/RC noise
filter with phase lead, otherwise, the internal components of the controller may be
damaged.
Please confirm that the power supply phases, rated voltage are consistent with
those indicated by the nameplate, otherwise, the controller may be damaged.
Do not perform dielectric strength test on the controller, otherwise, the controller 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 shall adopt lugs with insulating sleeves.
The sectional area of controller input and output cables should be selected according to
the controller power.
When the cables between the controller and the motor are longer than 100m, it is
suggested to use output reactor to avoid the controller failure caused by the over current
of the distribution capacitor.
The controller equipped with a DC reactor must be connected with a DC reactor between
the terminals of +1 and +2, otherwise the controller will not display after power on.
