Safety- The external voltage connected to the control cabinet remains live even whenthe robot is disconnected from the mains.- Additional connectionsManipulatorA 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 theOFF position. Power supply cables which are in motion during the working processmay be damaged.12 Emergency Release of Mechanical ArmIf an emergency situation occur where a person is caught by the mechanical robot arm,the brake release buttons should be pressed whereby the arms can be moved to releasethe person. To move the arms by manpower is normally possible on the smaller robots(1400 and 2400), but for the bigger ones it might not be possible without a mechanicallifting device, like an overhead crane.If power is not available the brakes are applied, and therefore manpower might not besufficient for any robot.Before releasing the brakes, secure that the weight of the arms not enhance thepress force on the caught person.13 Limitation of LiabilityThe above information regarding safety must not be construed as a warranty byABB Robotics that the industrial robot will not cause injury or damage even if allsafety instructions have been complied with.14 Related InformationInstallation of safety devicesChanging robot modesLimiting the working spaceDescribed in:Product Manual - Installation andCommissioningUser’s Guide - Starting upProduct Manual - Installation andCommissioningProduct Manual 13
