5 Installation Procedure
4.
Prepare and connect the wire ends as shown in
Wire Gauges and Tightening Torques on page 32
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 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.
