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. Tightening torque: 1.6 ±0.3 Nm
