Components in a control and switching unit might be very hot. Do not
touch any components with your hands. Doing so could result in
burns.
CAUTION
When removing a control and switching unit, install a blank panel.
If you continue using the Switch without attaching a blank panel, the
airflow in the Switch cannot be maintained. As a result, the
temperature inside the Switch will rise, possibly resulting in a failure.
In addition, the radio waves generated by the Switch might affect
another device, or the radio waves generated by another device might
affect the Switch, resulting in a malfunction.

A control and switching unit can be installed while the Switch is on.
Note, however, that the procedure varies depending on whether the Switch is on or
off.
In addition, the procedure also varies according to the installation conditions. Install
the unit while referring to the following figure.
NOTE
For details about steps 1 to 6 in the figure, see the description of the
