WARNING!
Use the required personal protective equipment. Wear protective gloves and long
sleeves. Some parts have sharp edges.
Keep the module in its package until you install it. After unpacking, protect the
module from dust, debris and moisture.
Lift/lower a heavy module with a lifting device. Use the designated lifting points.
See the dimension drawings. There is a lifting device available from ABB (order
code 3AXD50000047447).
Make sure that the drive cabinet is attached to the floor to prevent it from toppling
over. The cabinet has a high center of gravity. When you pull out heavy components
or power modules, there is a risk of overturning.
1. Stop the motors connected to the drive.
2. Repeat the steps described in section Electrical safety precautions (page 36) .
3. Open the cubicle door.
4. Close the inlet and outlet valve.
5. Lead the drain hoses into a suitable container. If necessary, extend the hoses. Open
the inlet and outlet drain valves. This will drain all modules in the cubicle.
6. After the cubicle has drained, disconnect the piping from the module.
7. 2×D8T module: If lower module needs to be replaced, remove the cooling fan (see the
fan replacement instructions).
8. Remove any shrouding above the module.

fuses (page 69) .
10. Disconnect the plug connector and fiber optic connectors in front of the module.
11. Remove the L-shaped busbars (3 pcs above the module).
12. Remove the module fastening screws (4 pcs).
13. Install the module lifting device to the cabinet. See Converter module lifting device for
drive cabinets hardware manual (3AXD50000210268 [English]).
14. Attach one lifting hook to the front lifting eye of the module and pull the module out 10
centimeters. Keep the lifting chain tight.
15. Attach the second lifting hook to the rear lifting eye, and pull the module completely out
of the cabinet. Keep the weight constantly on the lifting device.
