C Series Micro 1Ø Input Sensorless Vector Inverter Constant Torque Sensorless/Space Vector Control 0.5 to 3HP, 200-230VAC 1Ø input, 3Ø output Installation, Operation, & Maintenance Manual CAUTION, SAFETY WARNING As with all electrical products, read manual thoroughly before operating. Only qualified, expert personnel should perform maintenance and installation.Contact the nearest authorized service facility for examination, repair, or adjustment.
SAFETY INSTRUCTIONS Always follow safety instructions to prevent accidents and potential hazards from occurring. In this manual, safety messages are classified as follows: WARNING CAUTION Improper operation may result in serious personal injury or death. Improper operation may result in personal injury or property damage. Throughout this manual we use the following two illustrations to make you aware of safety considerations: Identifies potential hazards under certain conditions.
CAUTION 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. Be cautioned when touching. Otherwise, you may get a skin-burn. Do not apply power to a damaged inverter or to an inverter with parts missing even if the installation is complete.
(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. Reversing the polarity (+/-) of the terminals could damage the inverter. Only authorized personnel familiar with Cerus inverter should perform wiring and inspections.
Important User Information 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. This manual contains… Chapter Title 1 2 Basic information & precautions Installation Provides general information and precautions for safe and optimum use of the C series inverter.

Chapter 2. Installation 2.1 Installation precautions CAUTION z 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. z Install the inverter in a place where it is immune to vibration (5.9 m/s2 or less). The inverter is under great influence of ambient temperature z Install in a location where temperature is within the permissible range (14~122°F/-10~50°C).
Chapter 2. Installation z 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.
