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.

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

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.

2. When replacing the fuses, be sure to use a fuse with the same material and rating.

Before carrying out adjustment

1.With the power turned off, check that all of the connectors are securely connected by referring to “8-4. Description of connectors”.

2.Use the flowchart to check what sort of conditions the problem occurs under (#*).

3.Carry out the inspections for the problems in the order of the numbers in the “Cause” column.
