INTRODUCTION
About This Quick-Start Installation and User's Guide
This SEL-351P Recloser Control Quick-Start Installation and User’s
Guide helps you install, communicate with, set, and test the SEL-351P in
its EZ (“easy”) mode of operation. The EZ mode performs traditional
recloser control functions and operations.
SEL designed the SEL-351P based on the SEL-351 Distribution Relay.
The SEL-351P has full SEL-351 Relay functionality together with a
modified user interface designed for recloser control. When using the
SEL-351P as a traditional line recloser control, it is only necessary to
access the EZ Level (Access Level E) Settings. See the SEL-351P
Manual Técnico for complete information regarding the full
functionality of the SEL-351P.
The following sections are covered in this documentation:
• Table of Contents • Settings
• Introduction • Testing
• Installation • Battery
• Communications • Specifications
• Front-Panel Interface
Safety Information
This Quick-Start Installation and User’s Guide does not cover all of the
possible conditions or circumstances that can occur during the
installation, operation, or testing of the SEL-351P. If additional
information is necessary to install, communicate with, or make settings
to the control that is not provided in this documentation, please refer to
the SEL-351P Manual Técnico or contact SEL for assistance.
This Quick-Start Installation and User’s Guide contains three types of
hazard statements:
CAUTION: indicates a potentially haza7rdous situation which, if not
avoided, may result in minor or moderate injury or equipment damage.
WARNING: indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
DANGER: indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.

Introduction

!
CAUTION: The SEL-351P contains devices sensitive to Electrostatic
Discharge (ESD). When working on the relay module with cover removed,
work surfaces and personnel must be properly grounded or equipment
damage may result.
!
CAUTION: Do not connect this control to an energized recloser until all
control settings have been properly programmed and verified. Refer to the
Settings section of this guide for programming procedures. Failure to
comply can result in control and recloser misoperation, equipment damage,
and personal injury.
!
WARNING: Before installing, operating, maintaining, or testing this
equipment, carefully read and understand the contents of this guide.
Improper installation, handling, or maintenance can result in death, severe
personal injury, and/or equipment damage.
!
WARNING: This equipment is not intended to protect human life. Follow
all locally approved procedures and safety practices when installing or
operating this equipment. Failure to comply may result in death, severe
personal injury, and/or equipment damage.
!
DANGER: Contact with instrument terminals may cause electric shock that
can result in injury or death.

Serial Port and IRIG-B:
The serial ports and IRIG-B are
explained in the
Communications section.
The Wake-up port is explained
in the front of Section 10 in the
SEL-351P Manual Técnico.
Ratings:
Ratings for optoisolated inputs,
output contacts, current inputs,
voltage inputs, and power
inputs/outputs are given in the
Specifications section.
N/C Symbol:
A few of the connector
terminals are labeled N/C (not
connected). The N/C option
shown in the VOLTAGES
connector J3 legend (e.g.,
•VS, VS or N/C) refers to an
ordering option (order all the
voltage inputs or just voltage
in
p
ut VA
)
