1.3 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 during installation,
commissioning, and maintenance is guaranteed if the valid regulations are followed.
Voltage related risks, manipulator
A danger of low voltage is associated with the manipulator in:
• The power supply for the motors (up to 800 VDC).
• The user connections for tools or other parts of the installation (max. 230
VAC).
Voltage related risks, tools, material handling devices, etc.
Tools, material handling devices, etc., may be live even if the robot system is in
the OFF position. Power supply cables which are in motion during the working
process may be damaged.
