Cable Insulation Requirements for “Direct-to-Drive” Technology or Integral Isolation
Transformer
The following table identifies general wire categories that will be encountered
when installing the PowerFlex 7000 “A” Frame Drive. Each category has an
associated wire group number that is used in the following sections to identify the
wire to be used. Application and signal examples along with the recommended
type of cable for each group are provided. A matrix providing the recommended
minimum spacing between different wire groups run in the same tray or separate
conduit is also provided.
