Introduction Thank you for purchasing our high quality HC1-A series inverters. Before installation and operation please read these instructions in this manual thoroughly. For your safety, the product should only be installed, tested and adjusted by professional personnel. If you have any questions or problems, please contact our local agency. The information contained in this manual is subject to change without notice. CAUTION Indicates precautions that, if not avoided, could result in minor or moderate injury to personnel and damage to equipment. WARNING % ●Always turn off the input power supply before wiring. % ●Do not touch any inner part of the inverter when the charging lamp is still on shortly after the AC power is cut off. % ●Do not check signals while the inverter is running. % ●Do not attempt to modify or alter the inverter by yourself, doing so can result in electrical shock or injury or even explosion. 1. ●Be sure to ground the E terminal. 2. CAUTION % ●Do not perform voltage withstand tests on the inverter. % ●Never connect the AC main circuit power supply to output terminals U.V and W. % ●A CMOS IC is used in the control board. Handle the control board and CMOS IC carefully. The CMOS IC can be destroyed by static electricity if touched directly. % ●Installation, testing and maintenance must be performed by professional personnel. % ●The inverter should be discarded as industrial waste. Avoid burning. 1.1 Receiving Before unpacking please check the following: % ●Inspect the entire exterior of the inverter to see there are any scratches or other damage resulting from shipping. % ●Check if there is an inverter and an operation manual in the package as soon as you open the package. % ●Check the model on the nameplate on the side of the inverter to see if this is the right model you want. % ●Check if there is something wrong with the inner parts, wiring and circuit board. % ●Use a screwdriver or other tools to check for tightness. % ●Check if there is any other things in the machine. % ●Check if the operator buttons are all right. % ●Check if the optional device you ordered is contained in it. 1.2 Nameplate information MODEL： HC1A07D543B INPUT： 3 Ph 400V 50/60Hz OUTPUT ： 3 Ph 400V 17.5A 7.5KW Freq- Range: 0.1～400Hz TECORP ELECTRONICS CO., LTD. 2.Safety precautions CAUTION 1●Check to be sure that the voltage of the main circuit AC power supply matches the rated voltage of the inverter. 2 CAUTION % ●E symbol is the ground terminal, Be sure to ground the ground terminal. 1●Do not Connect electromagnetic switches or contactors to the output circuits. 2to the inverter. The installation diagram like this is forbidden. % ●Do not connect contactor to the input circuits. The service life of the inverter can be much longer if you start or stop the inverter by pressing the buttons FOR or REV,especially in those frequently starting and stopp conditions. 2.2 In delivery of current WARNING % ●Do not remove connectors on the inverter when in delivery of current. % ●Always have the protective cover in place before delivery of current to avoid electrical shock. 2.3 In running WARNING 1●Never add or remove motor group while in running, the surge current it created will cause damage to the inverter, even burn-up of the main circuit. 2 WARNING % ●Never remove the front cover of the inverter while in running. % ●Do not come close to the machine when the fault restart function is used. If the alarm is cleared, the machine may start moving suddenly. 1●The function of the STOP button can only be available after setting. It is different from the emergency stop button. Please note. 2 CAUTION % ●Do not touch the heat sink, braking resistor, or Braking Resistor Unit. These can become very hot. % ●Be sure that the motor and machine is within the applicable ranges before starting operation. % ●Do not check the signals while the inverter is running. % ●Be careful when changing inverter settings. The inverter has been set to suitable for general using in factory. % ●Do consider the noise,vibration,and the speed limit of the motor and the mechanical devices when the inverter is running at or above the frequency of 50Hz. 1. 3.
