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:
What You Need to Do
❐ Step 1: Remove power from the drive
❐ Step 2: Remove the old power structures
❐ Step 3: Install the new power structures
❐ Step 4: Connect the new power structures to the components in the
drive
❐ Step 5: Install the product identification label on the new power
structures
❐ Step 6: Start the drive

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.

9. Disconnect the cable to the cooling fan, mounted on the ASIC assembly
cover, from connector X1 on the ASIC board and remove the ASIC
assembly cover from each power structure.
10. Disconnect the fiber optic cables (H1 - H7) from each ASIC board.
11. Disconnect the cable from connector H903 on each ASIC Feedback
board.
12. For drives with 700H control, disconnect the +24V supply cable from
connector X10 on ASIC board #1.
13. For drives with DC input, disconnect the external precharge circuitry
from connectors X9 and X15 from each ASIC board.

14. Pull the rubber grommet, through which the ASIC board and Power
Supply Voltage Feedback board wire bundles are routed, out of the
drive frame and secure the wire bundles away from the frame of the
power structures.
15. Disconnect the fan control cables and, for drives with AC input,
disconnect the precharge cable from the Rectifying modules located to
the left of the ASIC board.

16. For drives with 700H control, continue with step 19 on page 11. For
drives with 700S control, disconnect the DC bus connection cable from
the connector J2 and the motor feedback connection cable from
connector J1 at the top of the Power Supply Voltage Feedback board on
Power Structure #1 (see illustration below for location).
17. Carefully disconnect the fiber-optic cables from sockets J4 and J5 on
the side of each of the Power Supply Voltage Feedback boards and
carefully set them aside (see illustration below for location).
Important:Minimum inside bend radius for fiber-optic cable is 25.4 mm (1
in.). Any bends with a shorter inside radius can permanently
damage the fiber-optic cable. Signal attenuation increases with
decreased inside bend radii.
!
ATTENTION: Hazard of permanent eye damage exists when
using optical transmission equipment. This product emits intense
light and invisible radiation. Do not look into fiber-optic ports or
fiber-optic cable connectors.

Feedback board assemblies to the fan housing on the power structures
and carefully remove the Power Supply Voltage Feedback board
assemblies.

20. Remove the two hexagonal screws that secure each power structure to
the enclosure frames.
21. Follow the instructions in publication PFLEX-IN014…, Installation
Instructions - PowerFlex 700S / 700H High Power Maintenance Stand,
to install the Maintenance Stand (part number 20-MAINSTND).
Remove each power structure by sliding it onto the rails of the
Maintenance Stand.
Note: The Maintenance Stand is designed for removing power
structures from drives supplied in Rittal TS8 enclosures. Alternate
means of removal will be necessary for other types of enclosures.
22. Follow the instructions in publication PFLEX-IN005…, Installation
Instructions - Lifting & Mounting PowerFlex 700S and 700H Drives
(Frame 10 - 14), supplied with the new power structures, to lift the
power structures off of the Maintenance Stand.
Remove screws - one each side of enclosure
12 PowerFlex® 700S and 700H Frame 14 Replacement Power Structures
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
and 700H Drives Frames 9 - 14, for tightening torques of power and motor
terminations.
Step 4: Connecting the
Power Structures to
Components in the Drive
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.
– Refer to PowerFlex 700S Phase II Drives Connections:
on page 16 for
a PowerFlex 700S Phase II circuit board connection diagram.
– Refer to PowerFlex 700H Connections:
on page 19 for a PowerFlex
700H circuit board connection diagram.
Important:If the drive has DC input, you must also connect the
precharge circuit. Refer to Pre-Charge Connections on
Drives with DC Input on page 21.
