A DANGER
Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall outlet
before
~~ening
the face plate
of
the control box. Touching areas where high voltage:; art: present can result in
severe tnjury.
9-1. Precautions at the time
of
adjustment
Pay attention
to
the following when opening the control
box
for
maintenance.
Electric shock
Some large capacitors may have a high voltage remaining in them for up to 5 minutes after the power
is
turned off.
To
prevent electric shock, wait at least 5 minutes after the power is turned off before doing the following:
• Opening and closing the control box
• Replacing fuses
• Separating and joining connectors
• Measuring resistance
• Doing anything with a possibility of touching something inside the control box
Some adjustments require measuring the voltage while the power is turned on with the control box kept open.
In
such a case, be careful not to touch any place other than that for the measurement.
In
addition, always keep in mind that
a high voltage remains for about
5 minutes after power is turned off.
Injury
While the power is turned on, the cooling fan
of
the control box operates; be careful not to
get
caught in it.
When separating
or
rejoining connectors, and measuring something, be careful not to cut your fingers on metal parts such
as heat sinks and covers.
