Step 3: Installing the New
Power Structures

Install the new power structures in reverse order of removal. Refer to the
publication PFLEX-IN006…, Installation Instructions - PowerFlex 700S

1. For drives with AC input, connect the precharge cable and remove the

jumper from the fan control connector and connect the fan control cable
from the Rectifying modules to the Power Structure.

2. Use the tables and illustrations below to make all connections between

the ASIC, ASIC Feedback, Common Mode Filter, Power Supply
Voltage Feedback and Fiber Optic Star Interface (700S) or Star Coupler
(700H) circuit boards for your installation.
