Safety precautionsThe items described in these instructions and on the inverter itself are very important so that you can use the inverter safely prevent injury to yourself and other people around you as well as prevent damage to property in the area. Thoroughly familiarize yourself with the symbols and indications shown below and then continue to read the manual. Make sure that you observe all warnings given.Explanation of markingsMarkingMeaning of markingDangerIndicates that errors in operation may lead to death or serious injury.WarningIndicates that errors in operation may lead to injury (*1) to people or that these errors may cause damage to physical property. (*2)(*1) Such things as injury, burns or shock that will not require hospitalization or long periods ofoutpatient treatment.(*2) Physical property damage refers to wideranging damage to assets and materials.Meanings of symbolsSymbolMeaning of Symbol0Indicates prohibition (Don39。t do it).What is prohibited will be described in or near the symbol in either text or picture form.oIndicates something mandatory (must be done).What is mandatory will be described in or near the symbol in either text or picture form.oIndicates danger.What is dangerous will be described in or near the symbol in either text or picture form.厶Indicates warning.What the warning should be applied to will be described in or near the symbol in either text or picture form.■ Limits in purposeThis inverter is used for controlling speeds of threephase induction motors in general industrial use.外、Safety precautions▼The inverter cannot be used in any device that would present danger to the human body or from which malfunction or error in operation would present a direct threat to human life (nuclear power control device, aviation and space flight control device, traffic device, life support or operation system, safety device, etc.). If the inverter is to be used for any special purpose, first get in touch with the people in charge of sales.▼This product was manufactured under the strictest quality controls but if it is to be used in critical equipment, for example, equipment in which errors in malfunctioning signal output system would cause a major accident, safety devices must be installed on the equipment.▼ Do not use the inverter for loads other than those of properly applied threephase induction motors in general industrial use. (Use in other than properly applied threephase induction motors may cause an accident.)1■ General operation DangerSee itemDisassemblyprohibited? Never disassemble, m
