Work on the electrical equipment of the robot must be performed by a qualified
electrician in accordance with electrical regulations.
The necessary protection for the electrical equipment and robot system during
construction, commissioning, and maintenance is guaranteed if the valid regulations
are followed.
All work must be performed:

• 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 main
switch to OFF) when repairing faults, disconnecting electric leads and
disconnecting or connecting units.
• The main supply to the robot must be connected in such a way that it can
be turned off from outside the working space of the robot.
• Make sure that no one else can turn on the power to the controller and robot
while you are working with the system. A good method is to always lock the
main switch on the controller cabinet with a safety lock.
• by qualified personnel
• on machine/robot system in deadlock
• in an isolated state, disconnected from power supply, and protected against
reconnection.
• Be aware of stored electrical energy (DC link) in the controller.
• Units such as I/O modules, can be supplied with power from an external
source.
• The mains supply/mains switch
• The power unit
• The control power supply (S4C 55 VAC, and S4Cplus 230 VAC)
• The rectifier unit (262/430 VAC and 400/800 VDC. Note: Capacitors!)
• The drive unit (400/800 VDC)
• The service outlets (115/230 VAC)
• The power supply unit for additional 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.
