Figure 8.6 Connect the Ground Wire
Note: 1. The option package includes two ground wires. Use the longer wire when plugging the option into connector CN5-C on the drive
side. Use the shorter wire when plugging the option into connector CN5-B. Refer to the option card instruction manual for more
information.
2. There are two screw holes on the drive for use as ground terminals (H). When connecting three options, two ground wires will need
to share the same drive ground terminal.
4. Prepare and connect the wire ends as shown in Figure 8.7 and Figure 8.8. Refer to Wire Gauges and
Tightening Torques on page 444 to confirm that the proper tightening torque is applied to each terminal. 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 contact other wiring. Insufficient
insulation may cause a short circuit and damage the option or drive.
