WARNING: After the Reset command is given and the alarm reset ......... 4–16

occurs, the motor will restart suddenly if the Run command is already active. Be sure to set the alarm reset after verifying that the Run command is off to prevent injury to personnel.

Cautions for Operations and Monitoring

CAUTION: The heat sink fins will have a high temperature. Be

........... 4–2

careful not to touch them. Otherwise, there is the danger of getting

 

burned.

 

CAUTION: The operation of the inverter can be easily changed

........... 4–2

from low speed to high speed. Be sure check the capability and

 

limitations of the motor and machine before operating the inverter.

 

Otherwise, it may cause injury to personnel.

 

CAUTION: If you operate a motor at a frequency higher than the

........... 4–2

inverter standard default setting (50Hz/60Hz), be sure to check the

 

motor and machine specifications with the respective manufacturer.

 

Only operate the motor at elevated frequencies after getting their

 

approval. Otherwise, there is the danger of equipment damage.

 

CAUTION: It is possible to damage the inverter or other devices in

........... 4–4

your application if the maximum current or voltage characteristics

 

of a connection point are exceeded.

 

Warnings and Cautions for Troubleshooting and Maintenance

WARNING: Wait at least five (5) minutes after turning off the input

........... 6–2

power supply before performing maintenance or an inspection.

 

Otherwise, there is the danger of electric shock.

 

WARNING: Make sure that only qualified personnel will perform

........... 6–2

maintenance, inspection, and part replacement. (Before starting to

 

work, remove any metallic objects from your person (wristwatch,

 

bracelet, etc.). Be sure to use tools with insulated handles. Other-

 

wise, there is a danger of electric shock and/or injury to personnel.

 

WARNING: Never remove connectors by pulling on its wire leads

........... 6–2

(wires for cooling fan and logic p.c.board). Otherwise, there is a

 

danger of fire or injury due to wire breakage.

 

CAUTION: When removing connectors, never pull the wires (wires

........... 6–2

for the cooling fan and logic P.C. board. Otherwise, there is danger

 

of fire due to wire breakage and/or injury to personnel.

 

CAUTION: Never test the withstand voltage (HIPOT) on the

......... 6–12

inverter. The inverter has a surge protector between the main circuit

 

terminals above and the chassis ground.
