PowerFlex® 700S and 700H Fan Inverter
Upgrade Kit (Frame 10-11)
Introduction
Use this document to upgrade the fan inverters on PowerFlex 700S or 700H
frame 10 or frame 11 drives.
ATTENTION: To avoid an electric shock hazard, ensure that all
power to the drive has been removed before performing the
!
following.
ATTENTION: To avoid an electric shock hazard, verify that the
voltage on the bus capacitors has discharged before performing
!
any work on the drive. Measure the DC bus voltage at the DC+ &
DC- terminals. The voltage must be zero.
ATTENTION: HOT surfaces can cause severe burns. Do not
touch the heatsink surface during operation of the drive. After
!
disconnecting power allow time for cooling.
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.
ATTENTION: This drive contains ESD (Electrostatic
Discharge) sensitive parts and assemblies. Static control
!
precautions are required when installing, testing, servicing or
repairing this assembly. Component damage may result if ESD
control procedures are not followed. If you are not familiar with
static control procedures, reference A-B publication 8000-4.5.2,
“Guarding Against Electrostatic Damage” or any other
applicable ESD protection handbook.

What You Need to Do
Step 1: Removing Power from the Drive
❐ Step 1: Remove power from the drive.
❐ Step 2: Remove the covers from the power structure.
❐ Step 3: Prepare the power structure for inverter assembly removal.
❐ Step 4: Remove the old inverter assemblies from the drive.
❐ Step 5: Remove the inverters from the old assemblies.
❐ Step 6: Install the inverters on the new assemblies.
❐ Step 7: Install the new inverter assemblies and prepare the drive for
use.
ATTENTION: To avoid an electric shock hazard, verify that the
voltage on the bus capacitors has discharged before performing
!
any work on the drive. Measure the DC bus voltage at the DC+ &
DC- terminals of the Power Terminal Block. The voltage must be
zero.
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 the DC bus voltage at the DC+ & DC- terminals on the Power
Terminal Block. The voltage must be zero.
