• 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.
• by qualified personnel
• on machine/manipulator system in deadlock
• in an isolated state, disconnected from power supply, and protected against
reconnection
• 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 (262/400-480 VAC and 400/700 VDC. Note: Capacitors!)
• The drive unit (400/700 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
