1.2.4.7 Risks associated with live electric parts
Voltage related risks, general
Work on the electrical equipment of the robot must be performed by a qualified
electrician in accordance with electrical regulations.
• Although troubleshooting may, on occasion, need to be carried out while the
power supply is turned on, the robot must be turned off (by setting the main
switch to OFF) when repairing faults, disconnecting electric leads and
disconnecting or connecting units.
• The main supply to the robot must be connected in such a way that it can
be turned off from outside the working space of the robot.
• Make sure that no one else can turn on the power to the controller and robot
while you are working with the system. A good method is to always lock the
main switch on the controller cabinet with a safety lock.
The necessary protection for the electrical equipment and robot system during
construction, commissioning, and maintenance is guaranteed if the valid regulations
are followed.
All work must be performed:
• by qualified personnel
• on machine/robot system in deadlock
• in an isolated state, disconnected from power supply, and protected against
reconnection.
Voltage related risks, IRC5 controller
A danger of high voltage is associated with, for example, the following parts:
• Be aware of stored electrical energy (DC link, Ultracapacitor bank unit) in
the controller.
• Units such as I/O modules, can be supplied with power from an external
source.
• The main supply/main switch
• The power supply (100-240 VAC)
• The drive unit (24 VDC)
• The external voltage connected to the controller remains live even when the
robot is disconnected from the mains.
• Additional connections.
Voltage related risks, robot
A danger of high voltage is associated with the robot in:
• The power supply for the motors (24 VDC)
• The user connections for tools or other parts of the installation (max. 240
VAC).
• The IRB 14000 gripper is powered by 24 V DC from the robot tool flange. A
risk for short-circuit and sparks exists. All installation and service works
should be done with power disconnected from the gripper and the tool flange.
