5 Safety
Switch off the industrial robot and secure it (e.g. with a padlock) to prevent
it from being switched on again. If it is necessary to carry out work with the
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 systems 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 Roboter 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 600 V) can be present in various components
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. De-
pending on the robot variant, the counterbalancing systems correspond to cat-
egory 0, II or III, fluid group 2, 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.
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 by unauthorized personnel. The incoming
power cable must be deenergized. The robot controller and mains supply
lead must then be checked to ensure that it is deenergized.
If the KR C4 or VKR C4 robot controller is used:
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 in the case of
the drives of the new generation. Parts remain energized. Death or severe
injuries may result.
