Installation107WARNING! As the inputs pictured above are not insulated according to IEC 60664,the connection of the motor temperature sensor requires double or reinforcedinsulation between motor live parts and the sensor. If the assembly does not fulfil therequirement,• the I/O board terminals must be protected against contact and must not beconnected to other equipmentor• the temperature sensor must be isolated from the I/O terminals.Drive-to-drive link (XD2D)The drive-to-drive link is a daisy-chained RS-485 transmission line that allows basicmaster/follower communication with one master drive and multiple followers.Termination activation jumper T (see section Jumpers above) next to this terminalblock must be set to the ON position on the drives at the ends of the drive-to-drivelink. On intermediate drives, the jumper must be set to the OFF position.Shielded twisted-pair cable (~100 ohm, for example PROFIBUS-compatible cable)must be used for the wiring. For best immunity, high quality cable is recommended.The cable should be kept as short as possible; the maximum length of the link is100 meters (328 ft). Unnecessary loops and running the cable near power cables(such as motor cables) must be avoided. The cable shields must to be grounded tothe control cable clamp plate on the drive as shown on page 102.The following diagram shows the wiring of the drive-to-drive link.X5:D2D...1TJ3Termination ONJCUDrive 1B2A3BGNDX5:D2D1J3Termination OFFJCUDrive 2B2A3BGNDTX5:D2D1TJ3Termination ONJCUDrive nB2A3BGND3.3 nF> 630 V AC3.3 nF> 630 V AC
