Prepare and connect the wire ends as shown in
and
Wire Gauges, Tightening Torques, and Crimp Terminals on page 20
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 terminal screws to the specified tightening torque. Loose electrical
connections could result in death or serious injury by fire due to overheating. Tightening screws beyond the
specified tightening torque may cause erroneous operation, damage 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.
