1 Safety1.2.2.5. Risks associated with live electric parts133HAC040633-002 Revision: -1.2.2.5. Risks associated with live electric partsVoltage related risks, general• Although trouble shooting may, on occasion, have to be carried out while the powersupply is turned on, the manipulator must be turne off(by setting the main switch toOFF)when repairing faults, disconnecting electric leads and disconnecting orconnecting units.• The main supply to the manipulator must be connected in such a way that it can beturned off outside the manipulator’s working space.Voltage related risks, controller IRC5A danger of high voltage is associated with the following parts:• 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 tools, or special power supply units for the machiningprocess.• The external voltage connected to the control cabinet remains live even when themanipulator is disconnected from the mains.• Additional connections• Be aware of stored electrical energy (DC link, Ultra Cap unit) in the controller.• Units inside the controller, for example I/O modules, can be supplied with power froman external source.Voltage related risks, manipulatorA 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, seechapter Installation and commissioning in the Product manual).Voltage related risks, tools, material handling devices and so onTools, material handling devices and so on may be live even if the manipulator system is inthe OFF position. Power supply cables which are in motion during the working process maybe damaged.
