robot controller switched on, the user must define additional safety mea-
sures to ensure the safe protection of personnel.
If it is necessary to carry out work with the robot controller switched on, this
may only be done in operating mode T1.
Label the system with a sign indicating that work is in progress. This sign
must remain in place, even during temporary interruptions to the work.
The EMERGENCY STOP devices must remain active. If safety functions
or safeguards are deactivated during maintenance or repair work, they
must be reactivated immediately after the work is completed.
Faulty components must be replaced using new components with the same
article numbers or equivalent components approved by KUKA Deutschland
GmbH for this purpose.
Cleaning and preventive maintenance work is to be carried out in accordance
with the operating instructions.
Robot controller Even when the robot controller is switched off, parts connected to peripheral
devices may still carry voltage. The external power sources must therefore be
switched off if work is to be carried out on the robot controller.
The ESD regulations must be adhered to when working on components in the
robot controller.
Voltages in excess of 50 V (up to 780 V) can be present in various compo-
nents for several minutes after the robot controller has been switched off! To
prevent life-threatening injuries, no work may be carried out on the industrial
robot in this time.
Water and dust must be prevented from entering the robot controller.
Counterbal-
ancing system
Some robot variants are equipped with a hydropneumatic, spring or gas cylin-
der counterbalancing system.
The hydropneumatic and gas cylinder counterbalancing systems are pressure
equipment and, as such, are subject to obligatory equipment monitoring and
the provisions of the Pressure Equipment Directive.
The user must comply with the applicable national laws, regulations and stan-
dards pertaining to pressure equipment.
Inspection intervals in Germany in accordance with Industrial Safety Order,
Sections 14 and 15. Inspection by the user before commissioning at the instal-
lation site.
The following safety measures must be carried out when working on the coun-
terbalancing system:
The manipulator assemblies supported by the counterbalancing systems
must be secured.
Work on the counterbalancing systems must only be carried out by quali-
fied personnel.
Hazardous
substances
The following safety measures must be carried out when handling hazardous
substances:
Avoid prolonged and repeated intensive contact with the skin.
Before work is commenced on live parts of the robot sys-
tem, the main switch must be turned off and secured
against being switched on again. The system must then be checked to en-
sure that it is deenergized.
It is not sufficient, before commencing work on live parts, to execute an
EMERGENCY STOP or a safety stop, or to switch off the drives, as this does
not disconnect the robot system from the mains power supply. Parts remain
energized. Death or severe injuries may result.
