9.3.7.1 Battery Pack Connection

9 Maintenance and Inspection
9.3 Grease Replenishment/Exchange Procedures
When performing maintenance such as replacement of a wire harness in
the manipulator, 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 disappearance of the encoder absolute data.
For the battery pack connection, refer to fig. 9-10 "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 battery packs. Install the caps attached to the bat-
tery backup connectors of the motors.
NOTE
Do not remove the battery pack in the connector base.
