Ground must be connected securely.If the ground is not securely connected, it could lead to electric shock or fire when a malfunction or current leak occurs.A WarningSee itemProhibited? Do not attach equipment (such as noise filters or surge absorbers) that has builtin capacitors to the output (motor side) terminals.That could result in a fire.■ Operations令 DangerSee itemProhibited? Do not touch inverter terminals when electrical power is going to the inverter even if the motor is stopped.Touching the inverter terminals while power is connected to it may result in electric shock.? Do not touch switches when the hands are wet and do not try to clean the inverter with a damp cloth. Such practices may result in electric shock.? Do not go near the motor in alarmstop status when the retry function is selected.The motor may suddenly restart and that could result in injury.Take measures for safety, . attaching a cover to the motor, against accidents when the motor unexpectedly restarts.3.3.3.oMandatory? Turn input power on after attaching the front cover.When storing inside the cabinet and using with the front cover removed, always close the cabinet doors first and then turn power on. If the power is turned on with the front cover or the cabinet doors open, it may result in electric shock.? Make sure that operation signals are off before resetting the inverter after malfunction.If the inverter is reset before turning off the operating signal, the motor may restart suddenly causing injury.3.3.4A WarningSee itemProhibited? Observe all permissible operating ranges of motors and mechanical equipment. (Refer to the motor39。10% when the load is 100% in continuous operation)If the input power voltage is not +10%, 15% of the rated power voltage (177。ll get burned if you touchthem.Avoid operation in any location where there is direct spraying of the following solvents or other chemicals. The plastic parts may be damaged to a certain degree depending on their shape, and there is a possibility of the plastic covers ing off and the plastic units being dropped.If the chemical or solvent is anything other than those shown below, please contact us in advance.(Table 1) Examples of applicable chemicals and solventsChemicalSolventHydrochloric acid (density of 10% or less)MethanolSulfuric acid (density of 10% or less)EthanolNitric acid(density of 10% or less)TriolCaustic sodaMesopropanolAmmoniaGlycerinSodium chloride (salt)(Table 2) Examples of unapplicable chemicals and solventsChemicalSolventPhenolGasoline, kerosene, light oilBenzenesulfonic acidTurpentine oilBenzolThinner3.2■ Transportation ■ Installation? DangerSee itemProhibited? Do not install or operate the inverter if it is damaged or any ponent is missing.This can result in electric shock or fire.? Do not place any inflammable objects nearby.If a flame is emitted due to malfunction, it may result in a fire.? Do not install in any location where the inverter could e into contact with water or other fluids.This can result in electric shock or fire. 2.oMandatory? Must be used in the environmental conditions prescribed in the instruction manual.Use under any other conditions may result in malfunction.? Must be installed in noninflammables such as metals.The rear panel gets very hot. If installation is in an inflammable object, this can result in fire.? Do not operate with the front panel cover removed. This can result in electric shock.? An emergency stop device must be installed that fits with system specifications (. shut off input power then engage mechanical brake).Operation cannot be stopped immediately by the inverter alone, thus risking an accident or injury.? All options used must be those specified by Sumitomo Heavy Industries. The use of any other option may result in an accident.A\ WarningSee itemProhibited? When transporting or carrying, do not hold by the front panel covers.The covers may e off and the unit will drop out resulting in injury.? Do not install in any area where the unit would be subject to large amounts of vibration. That could result in the unit falling, resulting in injury.2.oMandatory? The main unit must be installed on a base that can bear the unit39。t stick your fingers into openings such as cable wiring hole and cooling fan covers. This can result in electric shock or other injury.?
