Electrical installation59JumpersJ1 ñ Determines whether Analogue input AI1 is used as a current or voltage input.J2 ñ Determines whether Analogue input AI2 is used as a current or voltage input.J3 ñ Drive-to-drive link termination. Must be set to the ON position when the drive isthe last unit on the link.External power supply for the JCU Control Unit (X1)External +24 V (minimum 1.6 A) power supply for the JCU Control Unit can beconnected to terminal block X1. Using an external supply is recommended ifï the application requires fast start after connecting the drive to the main supplyï fieldbus communication is required when the input power supply is disconnected.Drive-to-drive link (X5)Reserved.Safe Torque Off (X6)For the drive to start, both connections (OUT1 to IN1, and OUT2 to IN2) must beclosed. By default, the terminal block has jumpers to close the circuit. Remove thejumpers before connecting an external Safe Torque Off circuitry to the drive.
