Use and Lock the Main Switch
When you must touch the motors or machines, for example in maintenance, use the Main Switch to de-energize the
drive and lock the Main Switch Disconnect Handle in the OFF position as specified by this procedure.
Note:
Yaskawa recommends that you de-energize the drive before you turn the Main Switch from ON to OFF.
WARNING
Electrical Shock Hazard. Disconnect all power to the drive and remove all wires to do maintenance on the drive. If
you only turn OFF the built-in Main Switch before you do maintenance, there can be high voltage on input terminals R/L1, S/L2, and
T/L3 of the Main Switch and touching energized terminals will cause serious injury or death.
NOTICE
Damage to Equipment. Do not energize and de-energize the drive more frequently than one time each 30
minutes. If you frequently energize and de-energize the drive, it can cause drive failure.
NOTICE
Damage to Equipment. Do not cycle the Main Switch more than 6000 times. If you cycle the Main Switch more
times than the limit, it will cause the contact failure, or you cannot open or close the Main Switch.
NOTICE
Damage to Equipment. Make sure that you stop the motor before you turn ON/OFF the Main Switch. If you turn
ON/OFF the Main Switch during run, it can cause Main Switch failure.
