ABB IRB 4600 - 20/2.50, Product Manual

Page: 23 / 374

• Turntables or the like should be used to keep the operator out of the
manipulator's working space.
• The axes are affected by the force of gravity when the brakes are released.
In addition to the risk of being hit by moving manipulator parts, there is a risk
of being crushed by the parallel arm (if there is one).
• Energy stored in the manipulator for the purpose of counterbalancing certain
axes may be released if the manipulator, or parts thereof, are dismantled.
• When dismantling/assembling mechanical units, watch out for falling objects.
• Be aware of stored heat energy in the controller.
• Never use the manipulator as a ladder, which means, do not climb on the
manipulator motors or other parts during service work. There is a serious
risk of slipping because of the high temperature of the motors and oil spills
that can occur on the manipulator.
To be observed by the supplier of the complete system
• The supplier of the complete system must ensure that all circuits used in the
safety function are interlocked in accordance with the applicable standards
for that function.
• The supplier of the complete system must ensure that all circuits used in the
emergency stop function are interlocked in a safe manner, in accordance
with the applicable standards for the emergency stop function.

Description Safety risk
CAUTION
Motors and gears are HOT after running the
manipulator! Touching motors and gears may
result in burns!
With a higher environment temperature, more
surfaces on the manipulator will get HOT and
may also result in burns.
Hot components!
WARNING
Take any necessary measures to ensure that
the manipulator does not collapse as parts
are removed, e.g. secure the lower arm ac-
cording to repair instruction if removing mo-
tor, axis 2.
Removed parts may result in collapse of
manipulator!
WARNING
If the internal cables for the measurement
system have been disconnected during repair
or maintenance, then the revolution counters
must be updated.
Removed cables to the measurement sys-
tem
