Drive Installation
Chapter 2
Cable Insulation
The cable insulation requirements for the PowerFlex 7000 drive are given in the
tables below.
Table 2 - Cable Insulation Requirements for 18 Pulse and 6P / AFE Drives with Isolation
Transformer
Table 3 - Cable Insulation Requirements for “Direct-to-Drive” Technology
The following table identifies general wire categories that will be encountered
when installing the PowerFlex 7000 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.
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.
