(3) Battery replacement procedure
WARNING
CAUTION
POINT
Even if the connector for branch cable connection (black) is not connected to the
MR-BT6VCBL03M junction battery cable, an alarm will not occur. Check that
they are connected securely.
When you transport a servo amplifier and machine apart, disconnect only CN2
and CN4 of the servo amplifier. When other connectors or cables are
disconnected between the servo motor and battery, the absolute position data
will be deleted.

Before replacing a battery, turn off the main circuit power and wait for 15 minutes
or longer until the charge lamp turns off. Then, check the voltage between P+ and
N- with a voltage tester or 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.
The internal circuits of the servo amplifier may be damaged by static electricity.
Always take the following precautions.
Ground human body and work bench.
Do not touch the conductive areas, such as connector pins and electrical parts,
directly by hand.
The battery built in MR-BAT6V1BJ cannot be replaced. Therefore, please do not
disassemble the MR-BAT6V1BJ battery for junction battery cable. Otherwise, it
may cause a malfunction.
POINT
To avoid deleting data, replace the MR-BAT6V1BJ battery according to
procedures written in this section.
Before replacing batteries, check that the new battery is within battery life.
