Figure 7.4 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 Installation 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 7.5 and Figure 7.6. Refer to Wire Gauges and Tightening
Torques of PG-X3 Option on page 230 or Refer to Wire Gauges and Tightening Torques of PG-X3 Option on
page 230 to confirm that the proper tightening torque is applied to each terminal. Take particular precaution to ensure
that each wire is properly connected and that 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.
