14
shock and fire may occur.
Ensure the action is right after safe connection, otherwise physical
injury may occur.
Do not touch the conductor parts of output terminals directly, connect
the output wires with the casing or short circuit the output wires,
otherwise the electric shock, short circuit or fire may occur.
Do not touch the board circuit with hands directly, otherwise damage to
the components may occur.
Ensure the voltage of AC main circuit is in accordance with the rated
voltage of the intelligent integrated machine, otherwise electric shock,
damage to the controller and fire may occur.
Do not carry out any voltage-withstand test on the controller, otherwise
damage to the semi-conductors may occur.
Connect the braking resistor according to the wiring diagram, otherwise
fire may occur.
Tighten the screws according to the designated moment, otherwise fire
may occur.
Only professional technicians are allowed to do the design, installation,
debugging and operation on the device. Follow the designated
warnings, otherwise serious physical injury or property damage may
occur.
The input power lines should be tightened permanently and the device
needs to be grounded with proper techniques.
Dangerous voltage is still present on the following terminals even if the
intelligent integrated machine does not work; power supply terminals R,
S and T connect to motor terminals U, V and W.
Wait at least 10 minutes after disconnecting the power supply until the
machine is discharged.
2.4.4 Running precautions
Switch on the power supply after confirming the installation of terminal
covers and do not remove the cover in connection, otherwise electric
shock may occur.
Reset the fault after confirming the signal is disconnected, otherwise
physical injury may occur.
Do not perform any signal inspection and wrong operation in running,
