EM630/TC6A Closed-Loop Vector Hoist Inverter User Manual 3.2.6 Wiring on Output Side of Main Circuit 3.2.6.1 Inverter and Motor Connection Connect the output terminals U, V and W of the inverter to the input terminals U, V and W of the motor. Confirm whether a motor runs forward after receiving a forward running command. If not, please switch any two connection cables of output terminals U, V and W of inverter. 3.2.6.2 Never Connecting the Power Supply Cable to Output Terminals Never connecting the power supply cable to output terminals. If the output terminals are connected to the power supply, the internal parts of the inverter would be damaged.
3.2.6.3 Never Short-Circuiting or Grounding Output Terminals Never touch the output terminals with bare hands or connect the output cable to the inverter housing, so as to avoid electric shock or short circuit. In addition, Do not short-circuit the output cable. 3.2.6.4 Never Using an Phase-Shifting Capacitor Never connect a phase-shifting electrolytic capacitor or an LC/RC filter to the output circuit so as to prevent the inverter from being damaged. 3.2.6.5 Never Using an Electromagnetic Switch Do not connect a solenoid switch or an electromagnetic contactor to output circuits.
Otherwise, it will trigger the action of overcurrent or overvoltage protection circuit or damage the internal parts of the inverter. To set an electromagnetic contactor for the switch of the power supply, stop the inverter and the motor at first. 3.2.6.6 Noise Filter Installation at Output Side Connecting a noise filter to the output side of the inverter could reduce the inductive interference and the radio interference. Inductive interference: Signal line contains noises due to electromagnetic induction, thus resulting in incorrect actions of control devices. Radio interference:
high-frequency electromagnetic waves transmitted by the inverter and the cable will cause radio devices nearby to make noises while receiving signals. 35
