(4)  Battery replacement procedure 
 
WARNING 
Before replacing a battery, turn off the power and wait for 15 minutes or more until 
the charge lamp turns off. 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 a battery will erase the absolute position data. 
Before replacing batteries, check that the new battery is within battery life.
