Thank you for purchasing LS Variable Frequency Drives! SAFETY INSTRUCTIONS To prevent injury and property damage, follow these instructions. Incorrect operation due to ignoring instructions will cause harm or damage. The seriousness of which is indicated by the following symbols.
Page 2
WARNING Do not remove the cover while power is applied or the unit is in operation. Otherwise, electric shock could occur. Do not run the inverter with the front cover removed. Otherwise, you may get an electric shock due to high voltage terminals or charged capacitor exposure.
Page 3
CAUTION Install the inverter on a non-flammable surface. Do not place flammable material nearby. Otherwise, fire could occur. Disconnect the input power if the inverter gets damaged. Otherwise, it could result in a secondary accident and fire. Do not touch the inverter while the input power is applied or after removed.
Page 4
¨ Incorrect terminal wiring could result in the equipment damage. ¨ Reversing the polarity (+/-) of the terminals could damage the inverter. Only authorized personnel familiar with LS inverter should perform wiring and ¨ inspections. ¨ Always install the inverter before wiring. Otherwise, you may get an electric shock or have bodily injury.
Page 5
¨ In case of input voltage unbalance, install AC reactor. Power Factor capacitors and generators may become overheated and damaged due to potential high frequency noise transmitted from inverter. ¨ Use an insulation-rectified motor or take measures to suppress the micro surge voltage when driving 400V class motor with inverter.
Inspect the inverter for any damage that may have occurred during shipping. Check the nameplate on the inverter. Verify the inverter unit is the correct one for the application. The numbering system for the inverter is as shown below. U (480) LS Inverter Motor Capacity Series Name Input Voltage...
Chapter 1 – Installation 1.4 Other Precautions Do not carry the inverter by the front cover. Do not install the inverter in a location where excessive vibration is present. Be cautious when installing on presses or moving equipment. The life span of the inverter is greatly affected by the ambient temperature. Install in a location where temperature are within permissible limits (- 10 ~ 40 ℃).
