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。 WARNING or CAUTION. Each signal word has the following meaning throughout this manual. A This symbol means hazardous high voltage. It used to call your attention to items or operations that could be dangerous to your and other persons operating this equipment. Read these message and follow these instructions carefully. WARNING CAUTION This is the “ Safety Alert Symbol..” This symbol is used to call your atten tion to items or operations that could be dangerous to your or other persons operating this equipment. Read these messages and follow these instruc tions carefully. WARNING Indicates a potentially hazardous situation which, if not avoided, can result in serious injury or death. CAUTION Indicates a potentially hazardous situation which, if not avoided, can result in minor to moderate injury, or serious damage of product. The matters described under A CAUTION | may, if not avoided, serious results depending on the situation. Important matters are in CAUTION (as well as WARNING), so be sure to observe them lead to described NOTE NOTE: Notes indicate an area or subject of special merit, emphasizing either the product’ s capabilities or mon errors in operation or maintenance. HAZARDOUS HIGH VOLTAGE Motor control equipment and electronic controllers are connected to hazardous line voltages. When servicing drives and electronic controllers, there might be exposed ponents with cases or protrusions at or above line potential. Extreme care should be taken to protect against shock. Stand on an insulating pad and make it a habit to use only one hand when checking ponents. Always work with another person in case an emergency occurs. Disconnect power before checking controllers or performing maintenance. Be sure equipment is properly grounded. Wear safety glasses whenever working on an electronic controllers or rotating electrical equipment. PRECAUTIONS A WARNING : This equipment should be installed, adjusted and serviced by qualified electrical maintenance personal familiar with the construction and operation of the equipment and the hazards involved. Failure to observe this precaution could result in bodily injury. A WARNING : The user is responsible for ensuring that all driven machinery, drive train mechanism not supplied by Sumitomo Heavy Industries,Ltd., and process line material are capable of safe operation at an applied frequency of 150% of the maximum selected frequency range to the AC motor. Failure to do so can result in destruction of equipment and injury to personnel should a single point failure occur. A WARNING : For protection, install a leak breaker type with a high frequency circuit capable of large currents to avoid an unnecessary operation. The ground fault protection circuit is not designed to protect personal injury. A WARNING : HAZARD OF ELECTRICAL SHOCK. DISCONNECT INCOMING POWER BEFORE WORKING ON THIS CONTROL. A WARNING : SEPARATE MOTOR OVERCURRENT, OVERLOAD AND OVERHEATING PROTECTION IS REQUIRED TO BE PROVIDED IN ACCORDANCE WITH THE SAFETY CODES REQUIRED BY JURISDICTIONAL AUTHORITIES. A CAUTION: These instructions should be read and clearly understood before working on SF320 series equipment. A CAUTION: Proper grounds, disconnecting devices and other safety devices and their location are the responsibility of the user and are not provided by Sumitomo Heavy Industries,Ltd. ^ CAUTION: Be sure to connect a motor thermal switch or overload device to the SF320 series controller to assure that the inverter will shut down in the event of an overload or an overheated motor. A CAUTION: DANGEROUS VOLTAGE EXISTS UNTIL POWER LIGHT IS OFF. A CAUTION: Rotating shafts and above ground electrical potentials can be hazardous. Therefore, it is strongly remended that all electrical work conform to the National Electrical Codes and local regulations. Installation, alignment and maintenance should be performed only by qualified personnel. Factory remended test procedures, included in the instruction manual, should be followed. Always disconnect electrical power before working on the unit. ii ? WARNING This equipment has high leakage current and must be permanently(fixed) hard wired to earth via two independent cable. ?
