Planning the cabinet installation
40
Note 1:
The power cable shields can also be grounded to the drive module
grounding terminals.
Note 2:
Arranging the grounding inside the cabinet
Arrange the grounding of the drive module by leaving the contact surfaces of the
fastening points unpainted (bare metal-to-metal contact). The module frame will be
grounded to the PE busbar of the cabinet via the fastening surfaces, screws and the
cabinet frame. Alternatively, use a separate grounding conductor between the PE
terminal of the drive module and the PE busbar of the cabinet.
Ground also the other components in the cabinet according to the principle above.
Selecting the busbar material and preparation of the joints
If planning the use of busbars, note the following:
• Tin-plated copper is recommended but aluminium can also be used.
• The oxide layer from aluminium busbar joints must be removed and suitable anti-
oxidant joint compound applied.
Tightening torques
Apply the following torques to grade 8.8 screws (with or without joint compound) that
tighten electric contacts.
Planning the fastening of the cabinet
Note the following when planning the fastening of the cabinet:
• Fasten the cabinet to the floor from the front and to the floor or wall from the back.
• Always fasten the drive module from its fastening points to the cabinet. For
details, see the module installation instructions.
WARNING!
Do not fasten the cabinet by electric welding. ABB does not assume any
liability for damages caused by electric welding as the welding circuit may damage
electronic circuits in the cabinet.
