Preface

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.

Who Should Use This Manual 

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 

857- UM001

 and be familiar with the 

characteristics of the device.

Equipment

 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.

• A computer with an available USB port and a USB to RS-232 serial port 

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

. 

Supported Applications 

This publication is intended for use with 857 protection systems that are used 
on typical applications. For example, induction machines, motors controlling 
fans, pumps, compressors, conveyors, or feeder type loads such as transformer 
and capacitor bank protection.
