5. Select the proper type and length of communication cables and drop line.
Refer to the ODVA website (www.odva.org) for more information on network cabling.
Refer to Trunk Line and Drop Line Length on page 78 for details on selecting trunk line and drop line lengths.
Only connect network termination resistors (121 Ω, ±1%, 1/4 W) to nodes of the two ends of trunk line. Refer to
ODVA specifications for more details on DeviceNet termination.
6. Prepare and connect the communication cables to the terminal block as shown in Figure 8 and Figure 9 . Take
particular precaution to ensure that each wire is properly connected and wire insulation is not accidentally
pinched into electrical terminals.
WARNING! Fire Hazard. Tighten all terminal screws according to the specified tightening torque. Loose electrical connections could
result in death or serious injury by fire due to overheating electrical connections. Tightening screws beyond the specified tightening
torque may result in erroneous operation, damage to the terminal block, or cause a fire.
NOTICE: Heat shrink tubing or electrical tape may be required to ensure that cable shielding does not come into contact with other
wiring. Insufficient insulation may cause a short circuit that can damage the option or the drive.
