EM630/TC6A Closed-Loop Vector Hoist Inverter User Manual Danger 1. Wiring must be performed by authorized and qualified personnel so as to avoid unexpected accidents. 2. A circuit breaker must be installed between the inverter and the mains so as to prevent fire risk. 3. Ensure that the power supply is off before wiring, and ground the inverter in accordance with the applicable wiring standard so as to avoid electric shock. 4. The grounding terminal must be grounded so as to avoid electric shock and fire risk. Danger 1. Never connect input power supply cables to output terminals U, V and W of the inverter.
Pay attention to the terminal symbols and connect to the terminals correctly so as to prevent risks of damaging the inverter. 2. Be sure that the wiring meets EMC requirements and local safety standards. Cables should be in recommended sizes so as to prevent accident risk. 3. Do not connect braking resistor to DC bus terminals + and – so as to prevent fire risk. Tighten terminals with a screwdriver of specified torque so as to prevent fire risk. 4. Do not connect a phase-shifting capacitor or an LC/RC noise filter to output circuits. 5. Do not connect a solenoid switch or an electromagnetic contactor to output circuits.
Otherwise, it will trigger the action of the overcurrent protection circuit or even damage the internal parts of the inverter. 6. Do not disconnect internal cables of the inverter, or else this may possibly damage the internal parts of the inverter. Before Power-on: Caution 1. Verify that the input voltage is identical to the rated voltage of the inverter, input terminals R, S and T and output terminals U, V and W are correctly connected, there are no short circuit phenomena for the wiring of inverter and its peripheral circuits, and all wires are in good connection. Otherwise, this may result in inverter damage. 2.
Never perform voltage withstanding test on the inverter, because it has been done at the factory. Otherwise, this may result in accident. Danger 1. The front cover of the inverter must be closed before the inverter is powered on. Otherwise, it may result in an electric shock. 2. The wiring of all peripherals must be conducted in accordance with the guide of this manual. Otherwise, it may result in an electric hazard. After Power-on 3
