1.2.2.5. 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 outside the robot’s working space.
Voltage related risks, controller S4Cplus
A danger of high voltage is associated with the following parts:
•
Be aware of stored electrical energy (DC link) in the controller.
•
Units inside the controller, e.g. I/O modules, can be supplied with power from an
external source.
•
The mains supply/mains switch
•
The power unit
•
The power supply unit for the computer system (230 VAC)
•
The rectifier unit (400-480 VAC and 700 VDC. Note: Capacitors!)
•
The drive unit (700 VDC)
•
The service outlets (115/230 VAC)
•
The power supply unit for tools, or special power supply units for the machining
process.
•
The external voltage connected to the control cabinet remains live even when the robot
is disconnected from the mains.
•
Additional connections
