Default I/O diagram of the converter control unitThe diagram below shows the default I/O connections on the converter control unit, anddescribes the use of the signals/connections.The wire size accepted by all screw terminals (for both stranded and solid wire) is 0.5 …2.5 mm2 (24…12 AWG). The torque is 0.5 N·m (5 lbf·in).XD2D Drive-to-drive link1 BDrive-to-drive link (not in use by default)2 A3 BGND4 ShieldX485 RS485 connectionBCIO-01 connection (optional)ABGNDShieldXRO1…XRO3 Relay outputs11 NC XRO1: Not in use250 V AC / 30 V DC / 2 A12 COM13 NO21 NC XRO2: Fault(-1) 1) (Energized = no fault)250 V AC / 30 V DC / 2 A22 COM23 NO31 NC XRO3: Fan control (DC/DC converter running, fan control on)250 V AC / 30 V DC / 2 A32 COM33 NOXSTO XSTO connector1 OUT XSTO connector.
