This publication guides you through the 6 basic steps that are required to start
up your Allen-Bradley® 857 Protection System for the first time for simple
applications. The comprehensive protection functions of the Protection
System make it ideal for utility, industrial, marine, and offshore power
distribution applications. Because the Protection System is designed for global
applications, it includes both ANSI IEEE and IEC protective function
numbers and symbology.
This manual is intended for qualified personnel who understand the hazards
that are associated with electromechanical equipment installations.
Personnel must:
• Follow all applicable local, national, and/or international electrical
codes.
• Be able to program and operate motor/feeder protection devices of this
type and style.
• Have an understanding of the appropriate parameter settings and their
protective functions that are related to the load being controlled and
protected.
• Have access to the user manual
characteristics of the device.
The following equipment requirements must be followed and applied to use
this quick start procedure.
• The 857 Protection System is in a standalone installation.
• No load sharing or multiple motors on one Protection System.
• Access to an approved programming cable – catalog number
857VX003-3.

converter. Such as the Allen-Bradley 9300-USBS USB to Serial Adapter.
• The latest available version of the SetPointPS programming and
commissioning software tool that is downloaded and installed on a
portable computer. The SetPointPS software is available at
www.rockwellautomation.com.
This publication is intended for use with 857 protection systems that are used
on typical applications. For example, induction machines, motors controlling
