1.2.3.1. Risks associated with live electric parts
Voltage related risks, general
Voltage related risks, IRC5 controller
A danger of high voltage is associated with, for example, the following parts:
Voltage related risks, 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.

• 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.
• 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.
