5 Safety
 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 axes can be
moved directly by hand.
5.6.6 Labeling on the industrial robot
All plates, labels, symbols and marks constitute safety-relevant parts of the in-
dustrial 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
5.6.7 External safeguards
The access of persons to the danger zone of the industrial robot must be pre-
vented by means of safeguards. It is the responsibility of the system integrator
to ensure this.
Physical safeguards must meet the following requirements:
 They meet the requirements of EN ISO 14120.
 They prevent access of persons to the danger zone and cannot be easily
circumvented.
 They are sufficiently fastened and can withstand all forces that are likely
to occur in the course of operation, whether from inside or outside the en-
closure.
 They do not, themselves, represent a hazard or potential hazard.
 Prescribed clearances, e.g. to danger zones, are adhered to.
Safety gates (maintenance gates) must meet the following requirements:
 They are reduced to an absolute minimum.
Information about the options available for the various robot models
and about how to use them can be found in the assembly and oper-
ating instructions for the robot or requested from KUKA Deutschland
GmbH.
Moving the manipulator without drive energy can dam-
age the motor brakes of the axes concerned. The motor
must be replaced if the brake has been damaged. The manipulator may
therefore be moved without drive energy only in emergencies, e.g. for rescu-
ing persons.
Further information is contained in the technical data of the operating
instructions or assembly instructions of the components of the indus-
trial robot.
