12 Risks Associated with Live Electric Parts
Controller
A danger of high voltage is associated with the following parts:
- The mains supply/mains switch
- The power unit
- The power supply unit for the computer system (55 V AC)
- The rectifier unit (260 V AC and 370 V DC. NB: Capacitors!)
- The drive unit (370 V DC)
- The service outlets (115/230 VAC)
- The power supply unit for tools, or special power supply units for the machin-
ing process
- The external voltage connected to the control cabinet remains live even when
the robot is disconnected from the mains.
- Additional connections
Manipulator
A danger of high voltage is associated with the manipulator in:
- The power supply for the motors (up to 370 V DC)
- The user connections for tools or other parts of the installation (see Installation,
max. 230 V AC)
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.
