NOTE
Use the levers so that the connectors on the optional module and the
Switch can be disengaged correctly. When moving a lever, move the
right and left levers slowly and at the same time without exerting
excessive force.
Step 5
Remove the basic control unit. (Use the levers to remove the unit partway, and then
hold the sides to remove the unit the rest of the way.)

Components in a basic control unit might be very hot. Do not touch
any components with your hands. Doing so could result in burns.
CAUTION
When removing a basic control 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.
(2) Installing a basic control unit
A basic control 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.
