Action
Place the cabling to motor axis 6 correctly on
the upper arm and gently pull the connectors
through the hole on top of the wrist unit to
motor axis 6.
In case of excess of cable length:
•
put the excess cable in a loop in the
area shown in the figure and secure with
cable straps. Cables are longer in order
to fit different upper arm lengths.
Fasten the cable bracket, wrist unit with its at-
tachment screws. Two screws are visible at
the rear attachment point of the bracket and
the third is located at the bottom of the cable
bracket, in the center.
Note
Do not use stainless attachment screws!
There is a potential risk of galvanic corrosion.
Reconnect the connectors to motor, axis 6 and
refit the motor cover.
Refit the cover, upper arm tube and the cover,
wrist unit.
Make sure the cabling is placed correctly when
refitting the covers, and does not get jammed.
If any cable straps have been removed, refit
them to the harness.
Refit the cable attachment, rear.
If the connection between the SMB battery and
the SMB unit has been broken, the revolution
counters now must be updated!
