Installation and Commissioning

Connecting SignalsInstallation and Commissioning24 V I/O available for customer connections at:XT.31.2XT.31.1XT.31.424 V (via 2 A fuse)for own fuses, max. fuse size is 2 A to ensure breaking at short circuitNote! DSQC 374 can not trip any fuses.0 V (connected to cabinet structure)3.13.2 115/230 V AC supplyThe robot has a AC supply available for external and internal use.This voltage is used in the robot for supplying optional service outlets.The AC supply is not galvanically separated from the rest of the controller voltages.Technical dataVoltage115 or 230 VPermitted customer load Max. 500 VAFuse size 3.15 A (230 V), 6.3 A (115 V)AC supply is available for customer connections at:XT.21.1-5 230 V (3.15 A)XT.21.6-8 115 V (6.3 A)XT.21.9-13 N (connected to cabinet structure)3.14 External 24 V supplyAn external supply must be used in the following cases:• When the internal supply is insufficient• When the emergency stop circuits must be independent of whether or not the robothas power on, for example.• When there is a risk that major interference can be carried over into the internal24 V supplyAn external supply is recommended to make use of the advantages offered by thegalvanic insulation on the I/O units or on the panel unit.The neutral wire in the external supply must be connected in such a way as to prevent themaximum permitted potential difference in the chassis earth being exceeded. For example,a neutral wire can be connected to the chassis earth of the controller, or some othercommon earthing point.Technical data:Potential difference to chassis earth:Max. 60 V continuousMax. 500 V for 1 minutePermitted supply voltage: I/O units 19 - 35 V including ripplepanel unit 20.6 - 30 V including ripple48 Product Manual IRB 1400
