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 cause erroneous operation, damage the
terminal block, or cause a fire.
