2-30 Drive Installation
7000-UM150I-EN-P – June 2013 7000 “B” Frame
Power Wiring Selection (cont.) Cable Insulation
The cable insulation requirements for the PowerFlex 7000 drive are
given in the tables below.
A T T E N T I O N A T T E N T I O N 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.
