2 Notes for Maintenance
2.1 Wrist Unit
• Refer to Fig. 2-1 “Wrist Unit”.
The motor and encoder unit are provided to the wrist unit. The matching
surfaces of the wrist cover and the wrist unit are sealed with sealing bond
to prevent fumes from penetrating into the wrist unit.
After removing the wrist cover, make sure to reapply sealing bond
(ThreeBond 1206C).

• 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.
• Do not remove the battery pack in the connector base.
