Only qualified, expert personnel should perform maintenance and installation.Contact the nearest authorized service facility for examination, repair, or adjustment.
Page 2: Safety Instructions
Particular attention should be directed because dangerous voltage may be present. Keep operating instructions handy for quick reference. Read this manual carefully to maximize the performance of C series inverter and ensure its safe use. Do not remove the cover while power is applied or the unit is in operation.
Page 3: Operating Precautions
Do not install the drive on a flammable surface. Do not place flammable material nearby the drive. Otherwise, fire could occur. Remove the input power from the drive if a hardware failure occurs. Otherwise, it could result in a secondary accident and fire. The drive surface can emit high temperature.
Page 4 (2) Wiring Do not connect a power factor correction capacitor, surge suppressor, or RFI filter to the output of the inverter. The connection orientation of the output cables U, V, W to the motor will affect the direction of rotation of the motor. Incorrect terminal wiring could result in the equipment damage.
Page 5 The purpose of this manual is to provide the user with the necessary information to install, program, start up and to maintain the C series inverter. To assure successful installation and operation, the material presented on this manual must be thoroughly read and understood before proceeding.

Page 13: Installation
2.1 Installation precautions Handle the inverter with care to prevent damage to the plastic components. Do not hold the inverter by the front cover. It may fall off. Install the inverter in a place where it is immune to vibration (5.9 m/s The inverter is under great influence of ambient temperature Install in a location where temperature is within the permissible range (14~122°F/-10~50°C).
Page 14 When two or more inverters are installed or a ventilation fan is mounted in inverter panel, the inverters and ventilation fan must be installed in proper positions with extreme care taken to keep the ambient temperature of the inverters below the permissible value. If they are installed in improper positions, the ambient temperature of the inverters will rise and ventilation effect will be reduced.
