3.
Connect one end of the ground wire (H) to the ground terminal (I) using one of the remaining screws (C). Connect
the other end of the ground wire (H) to the remaining ground terminal and installation hole on the option (B) using
the last remaining provided screw (C).
Figure 79
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 (I). 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
Torques on page 155
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.
