Step by Step Guide


Step 1

Prepare a new set of 3 backup batteries for replacement.


Note: 
Be sure to replace all of three batteries with new ones at one time. 

Step 2

Turn the controller power OFF. 



Step 3

Remove the hexagon socket-head bolts (Allen bolts) from the battery support plate. 



Step 4

Pull out the battery support plate from the robot unit. 


Step 5

Remove the dummy connector cap from the battery board. 


Step 6

Connect a new battery (1st one) to the pin from which you have disconnected the dummy connector cap in Step 5. 


NOTE:
Do not disconnect old backup batteries before connecting a new one to  the pin from which the dummy connector cap is removed. If you do so, the  encoder positional data may be lost.

Step 7

Disconnect the old backup battery that is left next to the new battery  connected in Step 6, and then connect a new battery (2nd one). 


Step 8

Disconnect the old backup battery that is left next to the new battery  connected in Step 7, and then connect a new battery (3rd one). 


Note:
Be sure to replace all the three batteries with new ones at one time. Otherwise, the battery service life will become short.

Step 9

Remove the last old battery and connect the dummy connector cap disconnected in Step 5. 


Step 10 

Secure the battery support plate to the connector plate.
