Page 4: Important Information
Carefully inspect for shipping damage. Damage to the shipping carton is usually a good indication that it has received rough handling. Report all damage immediately to the freight carrier and your ABB rep- resentative. Verify that the items on the packing list or bill of lading agree with your own. -
Page 5: Introduction
- The actuators perform movements for positioning vanes and valves. Handle properly and with care. Otherwise, a hazard of bruise injuries may arise. - Only qualified specialists who have been trained, qualified and certified by ABB for these tasks are STOP authorized to mount and adjust the actuator and to make the electrical connection. -

Page 7: Lubrication
Lubrication Lubrication The spur wheel gearings of LME620AI / LME620AN are grease lubricated. Mounting position Any mounting orientation is permissible. To facilitate mounting and maintenance, however, it is recom- mended to use orientation IMV 1 (thrust rod downwards). In all mounting orientations the actuator may not be exposed directly to rain, snow or other environ- mental influences. -
