User-Supplied Equipment
To install and configure the adapter, you must supply the following:
❑A small flathead screwdriver
❑Network-specific cable to connect the adapter to the network. See the
network-specific documentation for the cable recommendations and
requirements.
❑Drive and adapter configuration tool, such as the following:
– PowerFlex 20-HIM-xx HIM

Safety Precautions Please read the following safety precautions carefully.
!
ATTENTION: Risk of injury or death exists. The PowerFlex
drive can contain high voltages that can cause injury or death.
Remove all power from the PowerFlex drive, and then verify
power has been discharged before installing or removing an
adapter.
!
ATTENTION: Risk of injury or equipment damage exists. Only
personnel familiar with drive and power products and the
associated machinery should plan or implement the installation,
startup, configuration, and subsequent maintenance of the product
using an adapter. Failure to comply may result in injury and/or
equipment damage.
!
ATTENTION: Risk of equipment damage exists. The adapter
contains electrostatic discharge (ESD) sensitive parts that can be
damaged if you do not follow ESD control procedures. Static
control precautions are required when handling the adapter. If you
are unfamiliar with static control procedures, see Guarding
Against Electrostatic Damage, publication 8000-4.5.2.
!
ATTENTION: Risk of injury or equipment damage exists. DPI
or SCANport host products must not be directly connected
together using 1202 cables. Unpredictable behavior due to timing
and other internal procedures can result if two or more devices are
connected this way.
!
ATTENTION: Risk of injury or equipment damage exists. If the
adapter is transmitting control I/O to the drive, the drive can fault
when you reset the adapter. Determine how your drive will
respond before resetting an adapter.
!
ATTENTION: Risk of injury or equipment damage exists.
Parameter 6 - [Comm Flt Action] lets you determine the action
of the adapter and connected drive if I/O communication is
disrupted. By default, this parameter faults the drive. You can set
this parameter so that the drive continues to run, however, take
precautions to verify that the setting of this parameter does not
create a risk of injury or equipment damage. When
commissioning the drive, verify that your system responds
correctly to various situations (for example, a disconnected cable
or a faulted controller).
!
ATTENTION: Risk of injury or equipment damage exists.
Parameter 7 - [RcvHrtBeat Time] lets you determine how long
it will take the adapter to detect network communication losses.
By default, this parameter sets the time to 120 seconds. You can
set it so that the duration is shorter, longer, or disabled. When set
to disabled, this also disables Parameter 6 - [Comm Flt Action].
Therefore, a communication fault action is ignored. Take
precautions to verify that the setting does not create a risk of
injury or equipment damage. When commissioning the drive,
verify that your system responds correctly to various situations
(for example, a disconnected cable).

Installing the Adapter
This chapter provides instructions for installing the adapter in a PowerFlex
7-Class drive.
Preparing for an Installation Before installing the adapter, verify that you have all required equipment.
See Required Equipment on page 1-3.
Connecting the Adapter to
the Drive
1. Remove power from the drive.
2. Use static control precautions.
3. Remove the drive cover or open the drive door.
4. Connect the Internal Interface cable to the DPI port on the drive and
then to the DPI connector on the adapter (see Figure 2.1).
5. Secure and ground the adapter to the drive (see Figure 2.2) by doing the
following:
–On a PowerFlex 70 drive, fold the Internal Interface cable behind the
adapter and mount the adapter on the drive using the four captive screws.
–On a PowerFlex 700, PowerFlex 700H or PowerFlex 700S drive,
mount the adapter on the drive using the four captive screws.

ATTENTION: Risk of equipment damage exists. The adapter
contains electrostatic discharge (ESD) sensitive parts that can be
damaged if you do not follow ESD control procedures. Static
control precautions are required when handling the adapter. If you
are unfamiliar with static control procedures, see Guarding
Against Electrostatic Damage, publication 8000-4.5.2.
!
ATTENTION: Risk of injury or death exists. The PowerFlex
drive can contain high voltages that can cause injury or death.
Remove power from the drive, and then verify power has been
discharged before installing or removing the adapter.

Connecting the Adapter to
the Network
1. Remove power from the drive.
2. Use static control precautions.
3. Route the LonWorks cable from the network through the bottom of the
PowerFlex drive (see Figure 2.2).
See the LonMark Layers 1-6 Interoperability Guidelines, Appendix A
‘Cable Requirements for the TP/FT-10 Channel’ for cable
recommendations and requirements.
4. Connect a 6-pin linear plug to the network cable.
Figure 2.3 shows a wiring example, and terminal names and their
functions.
