AC100 HIGH-PERFORMANCE VC INVERTER MANUAL INSTALLATION AND WIRING Chapter 3 Installation and Wiring 3.1 Safety Precautions This section specifies the various considerations necessary for reliable and safe operation of the product by users. Inverter Motor 10 ●When the inverter is installed in closed cabinet, please ensure the temperature at the air-in port below 40℃ by way of cooling fans or air conditioners and other cooling equipment to ensure the safe and reliable operation of the inverter. ●When installing, please cover the inverter with cloth or paper to prevent metal dust, oil, water and others. And remove these cover carefully after working.
● Please follow the ESD regulations when operating the inverter, otherwise, the inverter may be damaged. ●If several inverters are installed in a cabinet, enough space must be set aside on the upper part of the inverter in order to change the cooling fan. ●Inverter can’t work over rated range. Otherwise, the inverter may be damaged. ●When transporting the inverter, please hold the case firmly. There might be danger of inverter main body falling, personnel injury or inverter damage if only holding the pre-cover. ●Different motor has different max allowable running speed. Motor can’t run over the max allowable running speed.
●When inverter is running at low speed, the motor auto-cooling effect would seriously decrease. If motor runs at low speed for long term, it will be damaged for overheating. If needed, please use special motor for inverter. ●When constant speed machinery runs at inconstant speed, there might be sympathetic vibration. Please install vibration-proof rubber under motor rack or use jumping frequency control function. ●When using frequency inverter or working frequency power supply to drive, the torque characteristics are different. Please do confirm the torque characteristic of the equipment connected. ●The rated current of shift gear motor is different from that of standard motor.
Please confirm and choose the right frequency inverter. Moreover, please do switch the pole when the inverter input current is 0. Otherwise, it may bring inverter damage. ●The rated current of diving motor is higher than that of standard motor, please confirm and choose the right inverter. ●When the wiring distance between motor and inverter is far, the max torque of the motor would reduce due to voltage drop. So please use cable thick enough when the distance between the motor and the inverter is long.
