ABB ACS580-07-0495A-4 - Requirements Table

Guidelines for planning the electrical installation 51
 Requirements table
The following table shows how to select the motor insulation system and when ABB
requires optional drive du/dt and common mode filters and insulated N-end (non-drive
end) motor bearings. If the installation does not fulfill these requirements or improper
installation can shorten motor life or damage the motor bearings and voids the warranty.
The abbreviations used in the table are defined below.
