【正文】 C, set the carrier frequency 2 kHz or less and derate output current 80% or less. _____________________________________________________________________________________ Higher ambient temperature cause shorter equipment life. If there are some hot equipment near the inverter, keep it away from inverter as far as possible. When the inverter is installed in a cubicle and/or a box, temperature around inverter should be kept as above rating. Consider ventilation and clearance around the inverter. For safety reason,front cover should be closed and don’ t open it during operation. For safety requirement, the end application must be in accordance with BS EN602041. 42 5. WIRING /!\ WARNING /K Use 60/75176。 3% or less. 3) Frequency variation 177。The Available Solution Single phase input 200V class Three phase input 200V class Three phase input 400V class SF320 Series Instructions C€ ?Sumitomo Heavy Industries, Ltd. ? SAFETY For the Best Results with SF320 Series inverter, read this manual and all of the warning sign attached to the inverter carefully before installing and operating it, and follow the instructions exactly. Keep this manual handy for your quick reference. Definitions and Symbols A safety instruction (message) is given with a hazard alert symbol and a signal word。 4% or less. 4) Voltage distortion THD = 10% or less. 2. Installation 1) Use filter designed for SF320 inverter. 3. Wiring 1) Sielded wire(screened cable) is required for motor wiring, and length is less than 50m. 2) Carrier frequency must be setting less than 5kHz to satisfy EMC requirement. 3) Separate the main circuit wiring from signal/process circuit wiring. 4. Environment condition When using a filter, keep the following condition. 1) Ambient temperature : 10 to 400C 2) Humidity : 20 to 90 % RH (no dew condensation) 3) Vibrations : m/s2( G) 1055Hz 4) Location : 1000 meter or less altirude, indoor (no corrosive gas or dust) iv TABLE OF CONTENTS Page 1.
