PowerFlex® 700S and 700H Frame 14
Replacement Power Structures
Introduction
Important:The Power Modules on PowerFlex 700S Phase II and 700H
frame 14 drives are matched at the factory and cannot be paired
with any other Power Modules. Therefore, when a Power
Module fails, you must replace both power structures on a
frame 14 drive.
Use this document to install replacement power structures on a frame 14
drive. This document covers the following replacement power structures:

ATTENTION: To avoid an electric shock hazard, verify that
the voltage on the bus capacitors has discharged before servicing
!
the drive. Check the DC bus voltage at the Power Terminal
Block by measuring between the +DC and -DC terminals,
between the +DC terminal and the chassis, and between the -DC
terminal and the chassis. The voltage must be zero for all three
measurements.
Remove power before making or breaking cable connections.
When you remove or insert a cable connector with power
applied, an electrical arc may occur. An electrical arc can cause
personal injury or property damage by:
• sending an erroneous signal to your system’s field devices,
causing unintended machine motion
• causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create
electrical resistance.

1. Turn off and lock out input power. Wait five minutes.
2. Verify that there is no voltage at the drive’s input power terminals.
3. Measure between the +DC and -DC terminals, between the +DC
terminal and the chassis, and between the -DC terminal and the chassis.
The voltage must be zero for all three measurements.
Step 2: Removing the Old
Power Structures

Before you can remove the old power structures from the drive, you must
remove the protective screens, protective covers and air flow plates from the
drive.
Note: The following steps must be completed for both power structures in
the drive.
Removing the Protective Screens and Covers
1. For NEMA/UL Type 1 enclosures, remove the screws that secure the
protective screens to the enclosures and remove the screens.
2. Remove the four M5 POZIDRIV screws that secures each of the three
pairs of protective covers to the drive power structures and remove the
protective covers.

Important:Mark all connections and wires before removal to avoid
incorrect wiring during assembly.
5. Remove the motor connections from the output power terminals on both
of the power structures. Note: The terminals are located in different
positions, depending on whether du/dt filters are installed or not.
6. Remove the ground connections from the bottom of the power structure
enclosures.
7. Remove the input connections from the incoming DC bus terminals at
the top of both power structures.
