Electrical installation32Connecting the control cablesI/O terminalsThe figure below shows the I/O connectors.The default connection of the control signals depends on the application macro inuse, which is selected with parameter 9902. See chapter Application macros for theconnection diagrams.Switch S1 selects voltage (0 (2)Ö10 V) or current (0 (4)Ö20 mA) as the signal typefor analog input AI. By default, switch S1 is in the current position.If DI5 is used as a frequency input, set group 18 FREQ INPUT parametersaccordingly.WARNING! All ELV circuits connected to the drive must be used within a zone ofequipotential bonding, i.e. within a zone where all simultaneously accessibleconductive parts are electrically connected to prevent hazardous voltages appearingbetween them. This is accomplished by a proper factory grounding.X1A: 1: SCR2: AI(1)3: GND4: +24 V5: GND6: DCOM7: DI18: DI29: DI310: DI411: DI5 digital or frequency inputX1B: 12: (RO)COM13: (RO)NC14: (RO)NOX1BX1ASCRAI+24VGNDCOMDI1DI2DI3DI4DI5COMNCNOGNDIU AI1 2 3 4 5 6 7 8 9 10 11 12 13 14S1Top position: I [0 (4)Ö20 mA], default for AIBottom position: U [0 (2)Ö10 V]IU
