2.3.2 Lifting

Improper Unit Lift!
Test lift unit approximately 24 inches to verify proper
center of gravity lift point. To avoid dropping of unit,
reposition lifting point if unit is not level. Failure to
properly lift unit could result in unit dropping and possibly
crushing operator/technician which could result in death
or serious injury and possible equipment or property-only
damage.
Always lift the frequency converter using the dedicated
lifting eyes. Use a bar to avoid bending the lifting holes.
CAUTION
The angle from the top of the frequency converter to the
lifting cables should be 60° or greater.
