SP2 Surge Protective Device
Installation & Operation
Instruction Manual
IB158003EN
Rev. 2
1.0 Introduction
This manual describes how to install a Surge
Protective Device (SPD) in parallel (shunt) across the
AC supply of the following types of electrical
systems:
• Single-Phase
• Split Phase
• Three-Phase Wye
• Three-Phase Delta
The SPD is designed to be installed on service
entrance, branch panels, and/or individual
equipment disconnects, and functions to protect
sensitive electronic equipment from damaging
voltage transients. The connecting wires do not
carry supply current. Instead, they carry only
short-duration currents that are associated with a
transient event.
These instructions do not cover all details,
variations, or combinations of the equipment, its
storage, delivery, installation, checkout, safe
operation, or maintenance. If you require further
information regarding a particular application or
installation that is not covered in this manual,
please contact Eaton’s Power Quality Technical Sup-
port at 1-800-809-2772, option 4, option 2.
1.1 Safety Precautions
A licensed/qualified electrician must complete all
instructions described in this manual in accordance
with the U.S. National Electrical Code, state and
local codes, or other applicable country codes. All
electrical codes supersede these instructions.
Improper installation can cause death, injury
and/or equipment damage. Follow all warnings
and cautions. Completely read and understand the
information in this instruction manual before
attempting to install or operate this equipment.
Improper wiring could cause death, injury, and/or
equipment damage. Only licensed/qualified
electricians who are trained in the installation and
service of electrical devices are to install and service
this equipment.
Use appropriate safety precautions and
equipment for arc flash protection.
During normal operation, hazardous voltages are
present inside the SPD.
When servicing the SPD, follow all safe work
practices to avoid electrical shock.
Do not perform a high-pot test with the SPD
connected to the electrical system. Failure to
disconnect the SPD during a high-pot test will result
in damage to the SPD.
Do not install with lead length less than six (6)
inches.
1.2 Catalog Numbering System
Series
Voltage Code
SP2-
120 = 120V single-phase
240 = 240V single-phase
240S = 240V split-phase
240D = 240 delta
480D = 480 delta
208Y = 120/208 wye
480Y = 277/480 wye
600Y = 347/600 wye
