Notes for Maintenance

When performing maintenance such as replacement of a wire harness in the manipulator,
NOTE
the encoder connector may be necessary to be removed. In this case, be sure to connect
the battery pack to the battery backup connector before removing the encoder connector.
Removing the encoder connector without connecting the battery pack leads to disappear-
ance of the encoder absolute data.
For the battery pack connection, refer to " Fig. 29 Battery Pack Connection ".

Battery Pack Connection

The connectors (crimped contact-pin) for the battery backup are installed at the end point of
the motors (BAT and OBT are marked). Connect the battery packs according to the following
procedure.
1. Removed the cap attached to the battery backup connector of the motors.
2. Connect the battery packs (HW9470932-A) with the battery backup connectors (BAT
and OBT are marked) located at the end point of the cables for the encoder. (Under
this condition, remove the encoder connector and carry out the maintenance checks).
3. Confirm all connectors connected after the maintenance check, and remove the bat-
tery packs. Install the caps attached to the battery backup connectors of the motors.
NOTE
Do not remove the battery pack in the connector base.
