2-30 Drive Installation
7000A-RM001A-EN-P – January 2011 7000 “A” Frame
Power Wiring Selection (cont.) Cable Insulation
The cable insulation requirements for the PowerFlex 7000 “A”
Frame 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.
