MR-J2M, cannot be used because their battery voltage specifications are
different from those of the MR-J4 series.

5.1.1 Battery replacement procedure
Model: MR-BAT or A6BAT
WARNING
Before mounting a battery, turn off the power and wait 15 min or longer until the
charge lamp turns off, then check the voltage between P and N with a voltage
tester, etc., otherwise an electric shock may occur. In addition, when confirming
whether the charge lamp is off or not, always check from the front of the servo
amplifier.
POINT
The internal circuits of the servo amplifier may be damaged by static electricity.
Always take the following precautions.
• Ground human body and work bench.
