• Brake release device (option)
The brake release device is designed for robot variants whose motors
are not freely accessible.
• Moving the wrist axes directly by hand
There is no release device available for the wrist axes of variants in
the low payload category. This is not necessary because the wrist ax-
es can be moved directly by hand.
Information about the options available for the various robot models and
about how to use them can be found in the assembly and operating in-
structions for the robot or can be requested from the manufacturer.
NOTICE
Damage to property due to moving the manipulator without drive
energy
Moving the manipulator without drive energy can damage the motor
brakes of the axes concerned.
• Only move the manipulator without drive energy in emergencies,
e.g. for rescuing persons.
• Perform brake test.
• The motor must be replaced if the brake has been damaged.
3.4.4 Labeling on the industrial robot
All plates, labels, symbols and marks constitute safety-relevant parts of
the industrial robot. They must not be modified or removed.
Labeling on the industrial robot consists of:
• Identification plates
• Warning signs
• Safety symbols
• Designation labels
• Cable markings
• Rating plates
Further information is contained in the technical data of the operating in-
structions or assembly instructions of the components of the industrial
robot.
3.5 Safety measures
3.5.1 General safety measures
The industrial robot may only be used in perfect technical condition in ac-
cordance with its intended use and only by safety-conscious persons. Op-
erator errors can result in personal injury and damage to property.
It is important to be prepared for possible movements of the industrial ro-
bot even after the robot controller has been switched off and locked out.
Incorrect installation (e.g. overload) or mechanical defects (e.g. brake de-
fect) can cause the manipulator or external axes to sag. If work is to be
carried out on a switched-off industrial robot, the manipulator and external
axes must first be moved into a position in which they are unable to move
on their own, whether the payload is mounted or not. If this is not possi-
