necessary information to let you install, connect, and set up the
Encoder Buffer Unit for safe, reliable operation. This preface covers
the following topics:
• Who should use this manual
• The purpose of this manual
• Terminology
• Common techniques used in this manual
• Allen-Bradley support
You should read this manual if you are responsible for the installation

configuration.
If you do not have a basic understanding of the products listed below,
contact your local Allen-Bradley representative for information on
available training courses before using this product.
Purpose of this Manual
• S Class Compact motion controller
• 1394 GMC System module
This manual is an installation and set up guide for the Encoder Buffer
Unit in both its 8 and 4 Way configurations. It describes the
procedures necessary to properly install and configure it into your
motion control system. Apart form the number of outputs both units
are identical and the information in this manual applies equally to
both. Where it is necessary to differentiate between them, this is
clearly indicated in the text.

Safety Precautions
The following general precautions apply to the Encoder Buffer Unit:
WARNING
!
Electric shock can kill. Make sure the Encoder Buffer
Unit is safely installed in accordance with the
Installation and Set-up chapters of this manual. Avoid
contact with electrical wires and cabling while power
is on. Only trained service personnel should open
the electrical cabinet.
This product contains stored energy devices. To
avoid hazard of electrical shock, verify that all
voltage on the capacitors has been discharged before
attempting to service, repair, or remove this unit. You
should only attempt the procedures in this manual if
you are qualified to do so and familiar with
solid-state control equipment and the safety
procedures in publication NFPA 70E and
BS-EN60204.
The system integrator is responsible for local safety
and electrical codes.
WARNING
!
An incorrectly applied or installed product can result
in component damage or a reduction in product life.
Wiring or application errors, such as undersizing or
inadequate DC supply, or excessive ambient
temperatures can result in a malfunction.
The Encoder Buffer Unit contains ESD (Electrostatic
Discharge) sensitive parts and assemblies. Static
control precautions are required when installing,
testing, servicing, or repairing this assembly.
Component damage can result if ESD control
procedures are not followed. If you are not familiar
with static control procedures, refer to Allen-Bradley
publication 8000-4.5.2, Guarding Against Electrostatic
Damage or any other applicable ESD Protection
Handbook.
