！
Danger : Do not connect or disconnect the connector when the power of the
Driver Unit is on.
！
Danger : A high voltage is applied to the connector after the power is turned on.
Take extra care for short circuit.
！
Danger : Check the orientation of the connector when inserting it. Though the
connector is self-lock type, be sure to insert it to the bottom. Otherwise
you cannot secure the connector.
！
Danger : A high voltage remains between the pins R+ and R- even the main
power is turned off. Be careful not to get an electric shock.
