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:
•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
Support at 1-800-809-2772, option 4, option 2.
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 volt-
ages are present inside the SPD.
When servicing the SPD, follow all safe work
practices to avoid electrical shock.
Warning No Serviceable Parts
Avertissement: Aucune piece remplacable
ou reparable
CAUTION ATTENTION
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.
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.

Avoid sharp bends
in conduit and longer
than necessary wire
lengths.
Keep conduit length
as short and
straight as possible.
Figure 2-2. Conduit Installation
2.1.2 Wall Mounting
Mount the SPD directly on a wall using the
SPD’s optional SP1MNTGKIT as follows:
1. Screw the wall bracket to the wall or other
mounting surface using two #10 screws of the
appropriate type (not provided) with the large
hole in the bracket at the top.
2. Thread the lead wires from the SPD through
the large hole and insert the integrated hub
into the large hole with the hub pointed
upwards.
3. Use the locknut (provided) to secure the SPD
hub to the bracket.
2.1 Mounting
The SPD can be mounted directly to the
electrical panel, or to a wall or din-rail with the
addition of an optional mounting kit, Catalog
number SP1DINRAILKIT.
IMPORTANT!
• Choose a mounting location for the SPD that
provides the shortest and straightest pos-
sible wiring (lead length) from the SPD to the
electrical system connections. Excessive lead
length and sharp bends will degrade SPD
performance.
• If the electrical system uses an isolated
ground, the SPD must be isolated from ground
using insulated conduit fittings.
• When using conduit, avoid using 90° elbows
and keep the conduit run as short and straight
as possible.
2.1.3 For DIN rail mounting
Mount the SPD directly on DIN rail using the
SPD’s optional SP1MNTGKIT as follows:
1. Snap the DIN rail clip into the two smallest
holes in the mounting bracket.
2. Thread the lead wires from the SPD through
the large hole in the bracket and insert the
integrated hub into the large hole.
3. Use the locknut (provided) to secure the SPD
hub to the bracket.
4. Snap the SPD and bracket to the DIN rail (not
provided) with the hub pointed upwards.
2.1.1 Conduit Installation
Mount the SPD directly to the electrical panel
using a 1/2” locknut as shown in Figure 2-1.
When mounting the SPD outdoors, use weath-
erproof conduit and fittings to maintain the
enclosure’s NEMA 4 rating. See Figure 2-2.

Refer to Section 1.2 and look at the label on the
SPD to verify that the SPD’s voltage rating and
wiring configuration matches that of the electri-
cal system. Use an AC voltmeter to measure the
system’s line voltage to ensure that the correct
model of SPD is being installed. Damage to the
SPD may result if it is connected to an electrical
system of a higher voltage or different wiring
configuration.

2.2 Wiring
IMPORTANT!
• Be sure to follow all national, state, and local elec-
trical codes when making wiring connections.
• When connecting the wires from the SPD to
the electrical system, cut the wires as neces-
sary to keep them as short as possible.
• To maximize the SPD’s performance, twist
and bind the wires together to reduce the
impedance of the wire (one twist/inch).
• If the system utilizes an isolated ground, the
SPD’s ground wire must be connected to the
system’s isolated ground bus.
1. Locate the electrical system’s applicable wiring
diagram in Section 2.3. Reference this wiring
diagram as necessary in Steps 2, 3, and 4.
2. Connect the SPD’s ground wire (green) to the
system’s ground connection. Delta only.
3. Connect the SPD’s neutral wire (white) to the
system’s neutral connection (not required for
3-phase delta systems – 240D, 480D, and
600D).
4. Connect the SPD’s phase A, B, and C
wires (black) to the system’s corresponding
phase A, B, and C connections accord-
ing to applicable national, state, and local
electrical codes.

3.0 Operation
3.1 Power Up and System Checkout
Apply system power. The LED should light.
If the connected LED does not light, remove
power, check connections, and test again. If
the LED still does not light, contact your sup-
plier.
With all phase voltages present, the LED indica-
tor reports the status of the protection elements
and is active when all of them are intact and
providing protection. Any loss of protection is
signaled when the LED extinguishes.
The device is not repairable and contains no
user serviceable parts. If the unit fails, as evi-
denced by the LED turning OFF, the unit must
be replaced. Please contact your distributor as
the SPD may be under warranty.
DO NOT use the Suppression Circuit Status
LEDs as an indication of the presence or ab-
sence of system phase voltages.
3.2 Routine Operation
After system power has been applied, the SPD
automatically begins to protect down-stream elec-
trical devices from damaging voltage transients.
