Limitorque MX DeviceNet Field Unit FCD
Figure 3.1 – Network cable connection to terminal block
NOTE: Recommended DeviceNet cable is Belden 3084A or equal. 121 ohm, ¼ W
Prepare the network cable for connection to the MX terminal block as follows.
aCAUTION: Strip stranded conductors carefully; do not damage the strands. This will weaken the conductor. Do not nick conductors or conductor insulation when stripping away the insulation. Nicking stresses the conductor and can cause the conductor to break. This type of damage may not be apparent and failure can occur later without warning.
NOTE: Excess cable should be cut, not coiled or looped, to prevent noise induction into the network and to reduce signal loss through unnecessarily long cable runs.
Cable Preparation
1.Remove two to three inches (5 to 8 cm) of the outer plastic jacket.
2.Separate the cable parts. Unbraid the shield and peel back the foil shield to the same point where the outer jacket was removed. Cut away the braided shield and the foil shield. Strip the insulation from the conductors approximately 0.4 inch (1 cm).
3.Apply heat shrink tubing to insulate the drain wire and to provide stress relief to the cable.
aCAUTION: Do not melt the insulation. NOTE: Ungrounded drain wires should be cut even with the cable sheath. The brand foil and drain wire should have heat shrink tubing applied.
4.Install ring tongue connectors. Flowserve recommends the use of Thomas & Betts
5.Connect the network cables to the MX terminal block as shown in Wiring Diagram
