Module Installation
The 1769-SDN module is suitable for use in an industrial environment when
installed in accordance with these instructions. Specifically, this equipment is
intended for use in clean, dry environments (Pollution Degree 2(1)) and with
circuits not exceeding Over Voltage Category II(2) (IEC 60664-1).(3)
Prevent Electrostatic Discharge
(1) Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation shall be expected.
(2) Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are
controlled and do not exceed the impulse voltage capability of the product’s insulation.
(3) Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.
ATTENTION
!
Electrostatic discharge can damage integrated circuits or
semiconductors if you touch bus connector pins. Follow these
guidelines when you handle the module:
•Touch a grounded object to discharge static potential.
•Wear an approved wrist-strap grounding device.
•Do not touch the bus connector or connector pins.
•Do not touch circuit components inside the module.
•If available, use a static-safe work station.
•When not in use, keep the module in its static-shield box.

Remove Power
ATTENTION
!
Remove power before removing or inserting this module. When
you remove or insert a module 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.

8Compact I/O DeviceNet Scanner Module
Publication 1769-IN060C-EN-P - May 2002
System Planning
Consider the following when planning your system:
•The scanner can communicate with up to 63 DeviceNet devices.
•The scanner, as a master, can own up to 63 slave I/O nodes.
•The scanner can simultaneously be a master and be a slave owned by
another DeviceNet master.
•A 1769-ECR (right end cap) or 1769-ECL (left end cap) is required to
terminate the end of the Compact I/O bus.
•Each bank of Compact I/O must have its own power supply (a MicroLogix
1500 acts as the power supply for modules directly connected to it).
•A Compact I/O power supply, or MicroLogix 1500 Base Unit, has limits in
the amount of +5V dc and +24V dc current it can supply to modules in its
I/O bank. These limits depend on the catalog number (e.g. 1769-PA2) of the
supply. A bank of modules must not exceed the current limits of the I/O
bank power supply or MicroLogix 1500 Base Unit.
Refer to the Compact 1769 Expansion I/O Power Supplies Installation
Instructions, publication 1769-5.14 or the MicroLogix 1500 User Manual,
publication 1764-UM001A-EN-P.
•The scanner has a distance rating of four, therefore the scanner must be
within four modules of the I/O bank’s power supply.
•Determine the DeviceNet baud rate based on standard DeviceNet
considerations.
•Consider the number of words of I/O data the host controller supports.
For more information on planning your DeviceNet network, refer to the DeviceNet
Cable System Planning and Installation Manual, publication DN-6.7.2.

Compact I/O DeviceNet Scanner Module 9
Publication 1769-IN060C-EN-P - May 2002
System Assembly
The module can be attached to an adjacent controller, power supply, or I/O
module. For mounting instructions, see “Panel Mounting”on page 10, or “DIN Rail
Mounting”on page 12. To work with a system that is already mounted, see
“Replacing a Single Module within a System”on page 13.
The following procedure shows you how to assemble the Compact I/O system.
1. Disconnect power.
2. Check that the bus lever of the module (A) is in the unlocked (fully right)
position.
3. Use the upper and lower tongue-and-groove slots (B) to secure the modules
together.
4. Move the module back along the tongue-and-groove slots until the bus
connectors (C) line up with each other.
5. Use your fingers or a small screw driver to push the bus lever back slightly
to clear the positioning tab (D).
6. Move the module’s bus lever fully to the left (E) until it clicks. Ensure it is
locked firmly in place.
ATTENTION
!
When attaching I/O modules, it is very important that the
bus connectors are securely locked together to ensure
proper electrical connection.

7. Attach an end cap terminator (F) to the last module in the system by using
the tongue-and-groove slots as before.
8. Lock the end cap bus terminator (G).
System Mounting
Minimum Spacing
Maintain spacing from
enclosure walls,
wireways, adjacent
equipment, etc. Allow 50
mm (2 in.) of space on all
sides for adequate
ventilation, as shown:
Allow at least 110 mm
(4.33 in.) of enclosure depth to accommodate the module and the DeviceNet
connector.
Panel Mounting
Mount the module to a panel using two screws per module. Use M4 or #8 panhead
screws. Mounting screws are required on every module.
IMPORTANT A 1769-ECR or 1769-ECL right or left end cap must be used to
terminate the end of the serial communication bus.
ATTENTION
!
During panel or DIN rail mounting of all devices, be sure that
all debris (metal chips, wire strands, etc.) is kept from falling
into the module. Debris that falls into the module could cause
damage on power up.
