WARNING
Before installing or removing MR-D01, turn off the power and wait for 15 minutes
or more until the charge lamp of the servo amplifier turns off. Then, confirm that
the voltage between P+ and N- is safe with a voltage tester and others.
Otherwise, an electric shock may occur. In addition, when confirming whether the
charge lamp is off or not, always confirm it from the front of the servo amplifier.
CAUTION
Avoid installing and removing MR-D01 repeatedly. Any contact failure of the
connector may be caused.
Avoid unsealing MR-D01 to be free of dust and dirt against the connector except
