1.2.2.5. Risks associated with live electric parts

Voltage related risks, general
Voltage related risks, controller IRC5
A danger of high voltage is associated with the following parts:
Voltage related risks, manipulator
A danger of high voltage is associated with the manipulator in:
Voltage related risks, tools, material handling devices and so on
Tools, material handling devices and so on may be live even if the manipulator system is in
the OFF position. Power supply cables which are in motion during the working process may
be damaged.

•
Although trouble shooting may, on occasion, have to be carried out while the power
supply is turned on, the manipulator must be turne off(by setting the main switch to
OFF)when repairing faults, disconnecting electric leads and disconnecting or
connecting units.
•
The main supply to the manipulator must be connected in such a way that it can be
turned off outside the manipulator's working space.
•
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 machining
process.
• The external voltage connected to the control cabinet remains live even when the
manipulator 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 from
an external source.
•
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
chapter Installation and commissioning in the Product manual).
