Risks associated with live parts
Control system
Dangerous voltage is carried by the following parts in an S3 control system.
Main power supply / power switch
Power unit
Power supply unit for computer system (220 V AC)
Rectifier unit (240 V AC and 340 V DC. Note: Capacitors!)
Drive unit (340 V DC)
Service outlets (110/220 VAC) (Option)
Power supply unit for tools or special power supply units for the machining process
External voltage connected to the control cubicle remains live even when the robot
system is disconnected from mains.
• Additional connections
Manipulator
Dangerous voltage may be present on the robot at:
• The power supply for the motors (to 340 VDC)
• User connections for tools or other parts of the installation (see Installation,
max. 220VAC)
Tools, material handling devices, etc
Tools, material handling devices, etc., may be live even if the robot system is in the OFF
position. Power supply cables which are in motion during the working process may be
damaged.
10. Limitation of liability.
The above information regarding safety must not be construed as a warranty by
