•Wiring the Output Side of Main Circuit Observe the following precautions when wiring the main output circuits. Connecting the Inverter and Motor Connect output terminals U/T1, V/T2, and W/T3 respective to the motor lead wires U, V, and W. Check that the motor rotates forward with the forward run command. Switch over any two of the output terminals to each other and reconnect if the motor rotates in reverse with the forward run command. Never Connect a Power Supply to Output Terminals Never connect a power supply to output terminals U/T1, V/T2, and W/T3. If voltage is applied to the output terminals, the internal circuits of the Inverter will be damaged. Never Short or Ground Output Terminals If the output terminals are touched with bare hands or the output wires come into contact with the Inverter case, an electric shock or grounding may occur. This is extremely hazardous. Do not short the output wires. Do Not Use a Phase Advancing Capacitor Never connect a phase advancing capacitor to an output circuit. The high-frequency components of the Inverter output may overheat and be damaged and may cause other parts to burn. Using a Magnetic Contactor Check the control sequence to make sure, that the magnetic contactor (MC) between the Inverter and motor is not turned ON or OFF during inverter operation. If the MC is turned ON while the Inverter is operating, a large inrush current will be created and the inverter’s overcurrent protection may operate. Cable Length between Inverter and Motor The cable between the Inverter and motor is 30 m max. •Ground Wiring Observe the following precautions when wiring the ground line. • Always use the ground terminal of the 200 V Inverter with a ground resistance of less than 100 Ω and that of the 400 V Inverter with a ground resistance of less than 10 Ω. • Do not share the ground wire with other devices, such as welding machines or power tools. • Always use a ground wire that complies with technical standards on electrical equipment and minimize the length of the ground wire. Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode and the ground terminal is too long, potential on the ground terminal of the Inverter will become unstable. • When using more than one Inverter, be careful not to loop the ground wire. OK NO Fig 2.8 Ground Wiring 2-14
Wiring Main Circuit Terminals •Connecting a Braking Resistor and Braking Unit (CDBR) Connect a Braking Resistor and Braking Unit to the Inverter like shown in the Fig 2.9. The example shows a braking resistor with integrated thermal overload switch. To prevent the braking unit/ braking resistor from overheating, design the control circuit to turn OFF the power supply using the thermal overload relay contacts of the units as shown in Fig 2.9. 200 V and 400 V Class Inverters with 3.7 to 18.5 kW Output Capacity Braking Resistor Inverter Thermal overload relay contact 200 V and 400 V Class Inverters with 22 kW or higher Output Capacity 2 CDBR Braking Unit Braking Resistor Inverter Thermal overload relay contact Thermal overload relay contact Fig 2.9 Connecting the Braking Resistor and Braking Unit 2-15
