Maintenance and Inspection
W ARNING
Only turn ON the input power supply after replacing the front cover or the terminal cover. Do not remove the cover while power is on.
Failure to observe this warning can result in an electric shock. (Refer to page 34 )
Never operate the digital operator or other switches when your hand is wet.
Failure to observe this warning can result in an electric shock. (Refer to page 34 )
Never touch the terminals while power is on, even if the power regenerative unit stops.
Failure to observe this warning can result in an electric shock. (Refer to page 34 )
CAUTION
Never touch the heatsink or input reactors since their temperature may be very high.
Failure to observe this caution can result in harmful burns to the body. (Refer to page 34 )
All the parameters of the power regenerative unit have been preset at the factory. Do not change the settings unnecessarily.
The power regenerative unit may be damaged. (Refer to page 34 )
