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 Danger See item Di sassembly prohibited • Never disassemble, modify or repair. This can result in electric shock, fire and injury. 2. 0 P rohibited • Never remove the front cover when power is on or open door if enclosed in a cabi. The unit contains many high voltage parts and contact with them will result in electric shock. • Don39。 t stick your fingers into openings such as cable wiring hole and cooling fan covers. This can result i n electric shock or other injury. • Don39。 t place or insert any kind of object into the inverter (electrical wire cuttings, rods, wires). This can result in electric shock or fire. • Do not allow water or any other fluid to e in contact with the inverter. This can result in electric shock or fire. 2. 1 2. 2. 2. o M andatory • Turn power on only after attaching the front cover or closing door if enclosed in a cabi. If power is turned on without the front cover attached or closing door if enclosed in a cabi. This can result in electric s hock or other injury. • If the inverter begins to emit smoke or an unusual odor, or unusual sounds, immediately turn power off. I f the equipment is continued in operation in such a state, the result may be fire. • A l ways turn power off if the inverter is not used for long periods of time since there is a possibility of mal function caused by leaks, dust and other material. I f power is left on with the inverter in that state, it may result in fire. 2. 1 3. 3. ytv Warning P rohibited contact Do not touch heat radiating fins. These devices are hot, and you39。 ll get burned if you touch them. 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. I f the chemical or solvent is anything other than those shown below, please contact us in advance.

This can result in electric shock or fire. • Do not place any inflammable objects nearby. I f 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. 1. 2. o M andatory • M ust be used in the environmental conditions prescribed in the instruction manual. Us e under any other conditions may result in malfunction. • M ust 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. 1. 1. 1. 1. 1. A\ Warning See item P rohibited • When transporting or carrying, do not hold by the front panel covers. The covers may e。
