Cable Insulation
These tables provide cable insulation requirements for the PowerFlex 7000 “B”
Frame drive.
Table 1 - Cable insulation requirements for AFE and 18 Pulse drives with isolation transformer
Table 2 - Cable insulation requirements for “Direct-to-Drive” technology
Table 3 identifies general wire categories common to the PowerFlex 7000 “B”
Frame drive. Each category has an associated wire group number, used in the
following sections to identify the appropriate wire to use. The table also provides
application and signal examples, along with the recommended type of cable for
each group, and a matrix providing the recommended minimum spacing between
different wire groups run in the same tray or separate conduit.
ATTENTION: Voltage ratings shown in the following tables are peak line-to-
ground. Some cable manufacturers rate voltage line-to-line RMS. Ensure the
cable meets the rating specified in the following tables.
