Prepare and connect the wire ends as shown in
and
.
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.
