* Short these pins if external regeneration resistor is not in use. If they remain open,
the alarm of “over heat” occurs.)
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 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 after the main
power is turned off. Be careful not to get an electric shock.
Danger : Operate the lever on both sides slowly when disconnecting the
connector.
