1.2.2.6. Risks associated with live electric parts
Voltage related risks, general
•
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 mains switch to OFF)
when repairing faults, disconnecting electric leads and disconnecting or connecting
units.
•
The mains supply to the robot must be connected in such a way that it can be turned
off from outside the robot’s working space.
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 mains supply/mains switch
•
The transformers
•
The power unit
•
The control power supply (230 VAC)
•
The rectifier unit (400-480 VAC and 700 VDC. Note: Capacitors!)
•
The drive unit (700 VDC)
•
The drive system power supply (230 VAC)
•
The service outlets (115/230 VAC)
•
The customer power supply (230 VAC)
•
The power supply unit for additional tools, or special power supply units for the
machining process.
•
The external voltage connected to the controller remains live even when the robot is
disconnected from the mains.
•
Additional connections.
Voltage related risks, manipulator
A danger of high 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, see the
chapter Installation and commissioning in the Product manual).
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.
