5 Installation ProcedureYASKAWA ELECTRIC SIEP C730600 43A YASKAWA AC Drive-Option Card DeviceNet Technical Manual 13 Communication Cable Wiring ProcedureFollow the instructions below to connect the communications cable to the terminal block.WARNING! Tighten all terminal screws according to the specified tightening torque. Tightening screws too tight could damage theterminal block, and leaving screws too loose can cause a short-circuit or drive malfunction.1. Connect the communications cable to the terminal block as shown in the diagram below.Note: Communication lines should be separated from main circuit wiring and other electrical lines. (Tightening torque: 0.5 to 0.6(Nxm) or 4.4 to 5.3 (inch-lbs)) for Network Cable Wiring.Figure 6Figure 6 Communication Cable Wiring2. Ensure all wiring connections are tightened and wire insulation is not pinched in the terminal block. Remove anystray wire strands that touch other terminals.3. After the terminal block is fully attached to the option card, tighten the screws on the left and right sides of theterminal block. (Tightening torque: 0.5 to 0.6 (Nxm) or 4.4 to 5.3 (inch-lbs)).Figure 7Figure 7 Terminal Block Installation Termination Resistor ConnectionA network termination resistor (121 Ω, ±1%, 1/4 W) must be connected only to nodes of the two ends of trunkline.
