Safety of personnel
When working inside the robot controller it is necessary to be aware of
voltage-related risks.
A danger of high voltage is associated with the following parts:
• Devices inside the controller, for example I/O devices, 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). 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 controller remains live even when the
robot is disconnected from the mains.
• Additional connections.
Therefore, it is important that all safety regulations are followed when doing
mechanical and electrical installation work.
