2. Verify that the Servopack CHARGE lamp (red LED) is unlit. 

3. Disconnect all the cables connected externally to the Servopack. cMain circuit power supply connector (CN7) dRegenerative resistor connector (CN8) eServo control power supply connector (1CN) fCables connected externally to the servo control board

Remove the ground wiring connected to the Servopack. 

Remove the four screws in the four corners of the Servopack.With the top and bottom grips, pull out the Servopack.  Install the new Servopack and reconnect the connectors in the reverse order of that lissted above.• Before replacing a servopack, confirm the version number of the JASPWRCA01… board and be sure to backup the data. (Refer to YASNAC XRC INSTRUCTION For CPU Circuit Board Replacement Procedure.) • After having replaced the servopack, load the backup data to the JASPWRCA01… board.
