Important User Information
Solid state equipment has operational characteristics differing from those of
electromechanical equipment. Safety Guidelines for the Application, Installation and
Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell
Automation sales office or online at http://www.ab.com/manuals/gi) describes some
important differences between solid state equipment and hard-wired electromechanical
devices. Because of this difference, and also because of the wide variety of uses for solid
state equipment, all persons responsible for applying this equipment must satisfy
themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or
consequential damages resulting from the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes.
Because of the many variables and requirements associated with any particular installation,
Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on
the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to use of
information, circuits, equipment, or software described in this manual.

Environment and Enclosure
SSI Servo Module 3
ATTENTION
This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC
publication 60664-1), at altitudes up to 2000 meters without derating.
This equipment is considered Group 1, Class A industrial equipment
according to IEC/CISPR Publication 11. Without appropriate precautions,
there may be potential difficulties ensuring electromagnetic compatibility in
other environments due to conducted as well as radiated disturbance.
This equipment is supplied as “open type” equipment. It must be mounted
within an enclosure that is suitably designed for those specific environmental
conditions that will be present and appropriately designed to prevent
personal injury resulting from accessibility to live parts. The interior of the
enclosure must be accessible only by the use of a tool. Subsequent sections of
this publication may contain additional information regarding specific
enclosure type ratings that are required to comply with certain product safety
certifications.
See NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided by
different types of enclosure. Also, see the appropriate sections in this
publication, as well as the Allen-Bradley publication 1770-4.1 (“Industrial
Automation Wiring and Grounding Guidelines”), for additional installation
requirements pertaining to this equipment.
Preventing Electrostatic Discharge
ATTENTION
This equipment is sensitive to electrostatic discharge, which can cause
internal damage and affect normal operation. Follow these guidelines
when you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• If available, use a static-safe workstation.
When not in use, store the equipment in appropriate static-safe
packaging.

Removal and Insertion Under Power
WARNING
When you insert or remove the module while backplane power
is on, an electrical arc can occur. This could cause an explosion
in hazardous location installations. Be sure that power is
removed or the area is nonhazardous before proceeding.
Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create electrical
resistance that can affect module operation.
Note the Power Requirements
This module receives power from the 1756 chassis power supply and requires
two sources of power from the backplane:
• 700mA at 5.1 V dc
• 2.5 mA at 24V dc
Add this current to the requirements of all other modules in this chassis to
prevent overloading the backplane power supply.

SSI Servo Module 5
Identifying Module Components
You received two components with your order:
• 1756-M02AS module
• RTB door label
If you did not receive these components, contact your Rockwell Automation
representative.
This module mounts in a 1756 chassis and uses a separately-ordered RTB or a
Bulletin 1492 Interface Module (IFM)
module uses one of the following RTBs:
• 1756-TBCH 36 position Cage clamp RTB
• 1756-TBS6H 36 position Spring clamp RTB
Use an extended-depth cover (1756-TBE) for applications with heavy gauge
wiring or requiring additional routing space. When using an IFM, consult the
documentation that came with it to connect wiring.
(1)
to connect all field-side wiring. This
IMPORTANT
Before you install your module, you should:
• install and ground a 1756 chassis and power supply.
• order and receive an RTB or IFM, and its components, for
your application.
(1)
The ControlLogix system has been agency certified using only the ControlLogix RTBs (i.e. 1756-TBCH,
1756-TBNH, 1756-TBSH and 1756-TBS6H). Any application that requires agency certification of the
ControlLogix system using other wiring termination methods may require application specific approval
by the certifying agency.

Installing the Module
You can install or remove the module while chassis power is applied.
WARNING
When you insert or remove the module while backplane power is
on, an electrical arc can occur. This could cause an explosion in
hazardous location installations. Be sure that power is removed
or the area is nonhazardous before proceeding.
Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create electrical
resistance that can affect module operation.

Wiring Registration Sensors
The registration inputs to the servo module can support 24V dc or 5V dc
registration sensors. These inputs should be wired to receive source current
from the sensor. Current sinking sensor configurations are not allowed
because the registration input common (IN_ COM) is shared with the other
24V dc servo module inputs.

Checking the LED Indicators
The module uses a single bi-colored LED to indicate module OK status and
bi-colored LED indicators to show individual feedback (FDBK) and drive
(DRIVE) status for both axes.
During power up, the module completes an indicator test. The OK indicator
turns red for 1 second and then turns to flashing green if the module passes
all its self tests.
