EM600 High-Performance Vector Control Inverter User Manual Wiring: Before Power-on: Caution 1. Verify that input voltage is identical to rated voltage of 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 the voltage withstanding test on inverter, because it has been done at the factory. Otherwise, this may result in accident. After Power-on Danger 1. Do not touch inverter or its peripheral circuits with wet hands to avoid the electric shock. 2.
If indicator is off or keypad does not display any information after power-on, please cut off power supply immediately. Never touch any terminal of R, S or T of inverter or 3 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 inverter and mains so as to prevent fire risk. 3. Ensure that power supply is off before wiring, and ground inverter in accordance with applicable wiring standard so as to avoid electric shock. 4. Grounding terminal must be grounded so as to avoid electric shock and fire risk. Danger 1. Never connect input power supply cable to output terminal U, V or W of inverter.
Pay attention to terminal symbols and connect to terminals correctly so as to prevent risks of damaging the inverter. 2. Be sure that wiring meets EMC requirements and local safety standards. Cables shall 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. 4. Tighten terminals with a screwdriver of specified torque so as to prevent fire risk. 5. Do not connect a phase-shifting capacitor or an LC/RC noise filter to output circuits. 6. Do not connect a solenoid switch or an electromagnetic contactor to output circuits.
Otherwise, it will trigger the action of overcurrent protection circuit or even damage the internal parts of inverter. 7. Do not disassemble internal cable of inverter. Otherwise, this may possibly damage the internal parts of inverter. Danger 1. The front cover of inverter must be closed before the inverter is powered on. Otherwise, it may result in an electric shock. 2. Wiring of all peripherals must be conducted in accordance with the guide of this manual. Otherwise, it may result in an electric hazard.
