DANGER
Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall outlet
before opening the cover of the control box. Touching areas where high voltages are present can result in severe
injury.
8-1. Precautions while carrying out adjustments
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
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.
