1.2 Manually releasing the brakes
Overview
Make sure that any attempt to release a person trapped by the robot arm does not
further increase the risk of injury.
Releasing the robot holding brakes will make it possible to move the robot manually,
but only small robots are light enough to be moved by human force. Moving larger
robots may require using an overhead crane or similar. Make sure that the right
equipment is available before releasing the brakes.
WARNING
Before releasing the brakes, make sure that the weight of the arms does not
increase the pressure on the trapped person, further increasing any injury.
WARNING
To use the brake release unit or brake release tool, the brakes must have power
supply from the controller or an external power supply.

DANGER
When releasing the holding brakes, the
robot axes may move very quickly and
sometimes in unexpected ways.
Make sure that the weight of the arm does
not increase the pressure on the trapped
person, further increasing any injury.
2
The brake release unit is placed in the ro-
bot frame or base, or on the robot control-
ler. Depending on the robot model, the
placing can vary slightly. The brake release
unit is protected with a plate or clamp. Locate the brake release unit.
Some robots have a brake release tool.
This shall be stored close to the robot. 3
The brake will function again as soon as
the button is released, or brake release
tool is removed. Release the holding brake on a particular
robot axis by pressing and holding the
corresponding button on the internal brake
release unit. 4
For robots with a brake release tool. Hold
the tool against the axis.
Move the robot so that the trapped person
is released. 5
Help the trapped person and make sure
he/she gets medical attention. 6
