SJ300 Inverter, Safety Messages, For the best results with the SJ300 Series inverter carefully read this manual and all of the. warning labels attached to the inverter before installing and operating it and follow the instruc. tions exactly Keep this manual handy for quick reference. Definitions and A safety instruction message includes a hazard alert symbol and a signal word WARNING or. Symbols CAUTION Each signal word has the following meaning. This symbol indicates HIGH VOLTAGE It calls your attention to items or operations. that could be dangerous to you and other persons operation this equipment Read the. message and follow the instructions carefully, This symbol is the Safety Alert Symbol It occurs with either of two signal words. CAUTION or WARNING as described below, WARNING Indicates a potentially hazardous situation that if not avoided can result. in serious injury or death, CAUTION Indicates a potentially hazardous situation that if not avoided can result. in minor to moderate injury or serious damage to the product The situation described. in the CAUTION may if not avoided lead to serious results Important safety. measures are described in CAUTION as well as WARNING so be sure to observe. STEP A step is one of a series of action steps required to accomplish a goal The. number of the step will be contained in the step symbol. NOTE Notes indicate an area or subject of special merit emphasizing either the. product s capabilities or common errors in operation or maintenance. TIP Tips give a special instruction that can save time or provide other benefits. while installing or using the product The tip calls attention to an idea that may not. be obvious to first time users of the product, Hazardous High Voltage.
HIGH VOLTAGE Motor control equipment and electronic controllers are connected to haz. ardous line voltages When servicing drives and electronic controllers there may be exposed. components with housings 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 compo. nents 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 electronic controllers or rotating machinery. General Precautions Read These First, WARNING This equipment should be installed adjusted and serviced by qualified electrical. maintenance personnel familiar with the construction and operation of the equipment and the. hazards involved Failure to observe this precaution could result in bodily injury. WARNING The user is responsible for ensuring that all driven machinery drive train mecha. nism not supplied by Hitachi Industrial Equipment Systems Co 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. WARNING For equipment protection install a ground leakage type breaker with a fast. response circuit capable of handling large currents The ground fault protection circuit is not. designed to protect against personal injury, HIGH VOLTAGE HAZARD OF ELECTRICAL SHOCK DISCONNECT INCOMING. POWER BEFORE WORKING ON THIS CONTROL, WARNING Wait at least five 5 minutes after turning OFF the input power supply before. performing maintenance or an inspection Otherwise there is the danger of electric shock. CAUTION These instructions should be read and clearly understood before working on. SJ300 series equipment, CAUTION Proper grounds disconnecting devices and other safety devices and their location.
are the responsibility of the user and are not provided by Hitachi Industrial Equipment Systems. CAUTION Be sure to connect a motor thermal disconnect switch or overload device to the. SJ300 series controller to assure that the inverter will shut down in the event of an overload or. an overheated motor, HIGH VOLTAGE Dangerous voltage exists until power light is OFF Wait at least 5 minutes. after input power is disconnected before performing maintenance. CAUTION This equipment has high leakage current and must be permanently fixed hard. wired to earth ground via two independent cables, WARNING Rotating shafts and above ground electrical potentials can be hazardous There. fore it is strongly recommended 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 recommended test procedures included in the instruction manual should be followed. Always disconnect electrical power before working on the unit. SJ300 Inverter, a Motor must be connected to protective ground via low resistive path 0 1. b Any motor used must be of a suitable rating, c Motors may have hazardous moving parts In this event suitable protection must be provided.
CAUTION Alarm connection may contain hazardous live voltage even when inverter is. disconnected When removing the front cover for maintenance or inspection confirm that. incoming power for alarm connection is completely disconnected. CAUTION Hazardous main terminals for any interconnection motor contact breaker filter. etc must be inaccessible in the final installation. CAUTION The end application must be in accordance with BS EN60204 1 Refer to the. section Step by Step Basic Installation on page 2 6 The diagram dimensions are to be. suitably amended for your application, CAUTION Connection to field wiring terminals must be reliably fixed having two indepen. dent means of mechanical support Using a termination with cable support figure below or. strain relief cable clamp etc, Terminal ring lug Cable support. CAUTION A three pole disconnection device must be fitted to the incoming main power. supply close to the inverter Additionally a protection device meeting IEC947 1 IEC947 3. must be fitted at this point protection device data shown in Determining Wire and Fuse Sizes. on page 2 14, NOTE The above instructions together with any other requirements are highlighted in this. manual and must be followed for continued LVD European Low Voltage Directive compli. Index to Warnings and Cautions in This Manual, Installation Cautions for Mounting Procedures. CAUTION Be sure to install the unit on flame resistant material such as a 2 6. steel plate Otherwise there is the danger of fire, CAUTION Be sure not to place any flammable materials near the inverter 2 6.
Otherwise there is the danger of fire, CAUTION Be sure not to let the foreign matter enter vent openings in the 2 6. inverter housing such as wire clippings spatter from welding metal. shavings dust etc Otherwise there is the danger of fire. CAUTION Be sure to install the inverter in a place that can bear the weight 2 6. according to the specifications in the text Chapter 1 Specifications Tables. Otherwise it may fall and cause injury to personnel. CAUTION Be sure to install the unit on a perpendicular wall that is not 2 6. subject to vibration Otherwise it may fall and cause injury to personnel. CAUTION Be sure not to install or operate an inverter that is damaged or 2 6. has missing parts Otherwise it may cause injury to personnel. CAUTION Be sure to install the inverter in a well ventilated room that 2 6. does not have direct exposure to sunlight a tendency for high temperature. high humidity or dew condensation high levels of dust corrosive gas. explosive gas inflammable gas grinding fluid mist salt air etc Otherwise. there is the danger of fire, CAUTION Be sure to maintain the specified clearance area around the 2 7. inverter and to provide adequate ventilation Otherwise the inverter may. overheat and cause equipment damage or fire, Wiring Warnings for Electrical Practices and Wire Specifications. WARNING Use 60 75 C Cu wire only or equivalent 2 13. WARNING Open Type Equipment For models SJ300 750H to SJ300 2 13. WARNING A Class 2 circuit wired with Class 1 wire or equivalent 2 13.
