Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall outlet

Electric shocks 
High voltages can remain in large-capacity capacitors for up to 5 minutes in some circumstances, even when the power has 
been turned off. Accordingly, wait at least 5 minutes after turning off the power before carrying out the following operations. 
•  Opening and closing the control box 

• Replacing fuses 
•  Inserting and disconnecting connectors 
•  Measuring resistance values 
•  Any other tasks that may involve touching components inside the control box 
Some inspection items require the control box to be open when the power is turned on and voltages are measured.   
At such times, be extremely careful never to touch anywhere other than the specified locations. In addition, note that high 
voltages may remain for up to 5 minutes after the power is turned off. 

Injury 
The fan inside the control box turns while the power is turned on, so be careful not to get anything caught in it. 
Be careful not to touch metallic objects such as the heat sink and cover when connecting and disconnecting connectors and 
making measurements. 
 

Be sure to note the following cautions when opening the control box to carry out inspections and adjustments.
