Installation and CommissioningOn-Site Installation2.7 Manually engaging the brakesAll axes are equipped with holding brakes. If the positions of the manipulator axes areto be changed without connecting the controller, an external voltage supply (24 V DC)must be connected to enable engagement of the brakes. The voltage supply should beconnected to the contact at the base of the manipulator or to the Burndy contact in thebase under the cover if, option 640 is chosen (see Figure 9).+24 V B80 V C10NOTE!Be careful not tointerchange the24 V- and 0 Vpins.In they are mixedup, damage canbe caused to aresistor and thesystem board.Burndy contact: R1.MP4-612 34 5 678 9 110 11 120 V+ 24 V DC13 14 15Figure 9 Connection of external voltage to enable engagement of the brakes.External power must be connected according to Figure 9. Incorrectly connectedpower can release all brakes, causing simultaneously movement of all axes.When the controller or the voltage supply is connected as illustrated above, the brakescan be engaged using the push-button on the manipulator, (see Figure 10).WARNING: Be very careful when engaging the brakes. The axes become activatedvery quickly and may cause damage or injury.Brake release buttonFigure 10 Location of the brake release button.Product Manual IRB 1400 15
