Lifting the converter
Obey these instructions when there are no ABB lift adapter bars in use:
1. Attach the lifting slings to holes of the lifting bars (a). Use long enough slings. See the
minimum lifting angle in the figure below.
WARNING! Divide the weight to all lifting bars and all holes. If you do not divide
the load evenly, the lifting bars can not carry the weight of the converter.
2. Tighten the slings steadily and make sure that the load is evenly divided.
3. Lift steadily.
4. Position the converter as near its final position as possible.
5. Remove the lifting bars and refasten the roof bolts to retain the degree of protection of
the cabinet. Store the loose lifting bars for later use.
