Rockwell Automation 20-XCOMM-DC-BASE User Manual
DPI External Communications Kit
Installation Instructions
These Installation Instructions are provided with the DPI
External Comms Kit. This document explains how to install
a communications adapter (sold separately) into the kit,
mount the kit in an enclosure, and connect the required
cables.
These instructions also describe the accessory AC Power
Adapter. See AC Power Adapter (20-XCOMM-AC-PS1)
page 3 for details.
External Comms Kit (20-XCOMM-DC-BASE)
Compatability
This kit is for use with only the following Allen-Bradley
communication adapters (sold separately):
• 20-COMM-E EtherNet/IP
• 20-COMM-C ControlNet (coax)
• 20-COMM-Q ControlNet (fiber)
• 20-COMM-D DeviceNet (Series B or later)
• 20-COMM-B BACnet MS/TP
• 20-COMM-M Modbus/TCP
The DPI External Comms Kit is typically used to provide an
additional network connection for a drive that already has a
20-COMM-* installed inside. For example, one network
may be used for control and a second network may be used
for configuration and data collection.
Installing the Communications Adapter
ATTENTION: Risk of equipment damage exists.
The communications adapter contains ESD
!
(Electrostatic Discharge) 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, refer to Guarding Against
Electrostatic Damage, Publication 8000-4.5.2.

3. Fasten the communication adapter into the enclosure
cover by using the adapter’s captive screws (Figure 1
This also grounds the adapter.
4. The communication adapter is supplied with two Internal
Interface (ribbon) cables. Use only the longer 15.24 cm
(6 in.) Internal Interface cable. Plug one end of the cable
into the mating connector on the power supply board in
the base of the Comms Kit enclosure.

5. Plug the other end of the Internal Interface cable into the
mating connector on the communication adapter.
6. If using an Allen-Bradley I/O Board option (20-
XCOMM-IO-OPT*) with the External Comms Kit,
install the I/O board into the kit at this time. For details,
see the I/O Board Installation Instructions provided with
the board. Otherwise, fasten the enclosure cover onto the
base using the two screws in the cover.

).
1. Before you install the communication adapter into the
Comms Kit, make sure to configure all of the adapter’s
switches and/or jumpers, if applicable, to appropriate
settings. Refer to the Communication Adapter User
Manual for details.
2. Remove the Comms Kit enclosure cover from the base
by unfastening its two screws.
ATTENTION: Risk of equipment damage exists.
During panel or DIN rail mounting, be sure to
!
prevent any debris (metal chips, wire strands, etc.)
from falling into the Comms Kit. Debris that falls
into the kit could cause damage on power up.
Panel or DIN rail mount the Comms Kit before connecting
the adapter to the network and drive.
Minimum Spacing
+
External Comms Kits can be zero-stacked (side-by-side
mounting). Allow 75 mm (3 in.) of space on the bottom of the
enclosure for cable entry. Allow at least 75 mm (3.2 in.) of
enclosure clearance depth to accommodate the Comms Kit.
Panel Mounting Using the Dimensional Drawing
Mount the Comms Kit to a panel using two M4 or #8
panhead screws (not included). Figure 2

Panel Mounting Procedure Using Comms Kit as a Template
The following procedure enables you to use the assembled
Comms Kit as a template for drilling holes in the panel.
1. Using the assembled Comms Kit as a template, carefully
mark the center of both holes on the panel.
2. Remove the Comms Kit to a clean location.
Electrical Connections
ATTENTION: Risk of equipment damage, injury
or death exists. Unpredictable operation may occur
!
if you fail to verify that parameter settings and
switch settings are compatible with your
application. Verify that settings are compatible
with your application before applying power to the
drive.
After the communication adapter (and I/O Board option, if
used) is installed and the Comms Kit is mounted, connect all
required cables. See Figure 4
the connectors and their connection procedures.

3. Drill and tap the mounting holes for the recommended
M4 or #8 panhead screws (not included).
4. Place the Comms Kit back on the panel, and check for
proper hole alignment.
5. Attach the Comms Kit to the panel using the mounting
screws.
DIN Rail Mounting
The Comms Kit can be mounted using these DIN rails:
• 35 x 7.5 mm (EN 50 022 - 35 x 7.5)
• 35 x 15 mm (EN 50 022 - 35 x 15)
Before mounting the Comms Kit on a DIN rail, open the
DIN rail latch. Press the DIN rail mounting area of the
Comms Kit against the DIN rail, and manually lock the DIN
rail latch (Figure 3
).
