Action
Turn on the electric power supply to the robot.
If the robot is not connected to the controller, power
must be supplied to the connector R1.MP according
to the section Supplying power to connector R1.MP
on page 59.
DANGER
When releasing the holding brakes, the robot axes
may move very quickly and sometimes in unexpec-
ted ways!
Make sure the payload is disassembled or tooling
is properly supported; otherwise, fast downward
movements of axis 3 may cause severe hits.
Release the holding brake by pressing the button
on the internal brake release unit.
Move the outer arm to a position where the axis 3
can be moved in full stroke.
Press the brake release button and move the shaft
to its upper and lower limits manually.
