(3) Battery replacement procedure
WARNING
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.
CAUTION
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.
POINT
Replacing battery with the control circuit power off will erase the absolute
position data.
Before replacing batteries, check that the new battery is within battery life.
Replace the battery while only control circuit power is on. Replacing battery with the control circuit power
on triggers [AL. 9F.1 Low battery]. However, the absolute position data will not be erased.

(a) Battery installation and removal procedure
1) Installation procedure
POINT
For the servo amplifier with a battery holder on the bottom, it is not possible to
wire for the earth with the battery installed. Insert the battery after executing the
earth wiring of the servo amplifier.
Install a battery, and insert the
plug into the CN4 connector.
Install a battery, and insert the
plug into the CN4 connector.

with a battery holder on the bottom
For the servo amplifier
with a battery holder on the front
2) Removal procedure
CAUTION
Pulling out the connector of the battery without the lock release lever pressed may
damage the CN4 connector of the servo amplifier or the connector of the battery.
While pressing the lock release lever,
pull out the connector.
While pressing the lock release lever, slide
the battery case toward you.
