Equipment Description
The Surge Protection Device (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
associated with a transient event.
Contact an IASD for information regarding a particular
application or installation not covered in this manual.

Introduction to Installation
This section describes how to install a Surge Protection
Device (SPD) in parallel (shunt) across the AC supply of
a split phase electrical system.
Installation
Refer to the label on the SPD to verify the voltage rating
and wiring configuration of the SPD matches that of the
electrical system. Use an AC voltmeter to measure the
system line voltage to verify 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.
Figure 3-2. Conduit Installation
Installation and Operation
Mounting
The SPD can be mounted directly to the electrical panel:
• Choose a mounting location for the SPD that
provides the shortest and straightest possible
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.
• See Figure 3-2. When using conduit, avoid using
90° elbows (A) and keep the conduit run as short
and straight as possible (B).
Conduit Installation
See Figure 3-1. Mount the SPD directly to the electrical
panel using a 1/2 in. locknut.
Wiring
When installing wiring:
• Follow all national, state, and local electrical codes
when making wiring connections.
• When connecting the wires from the SPD to the
electrical system, cut the wires as necessary 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. See Figure 3-3. Connect the SPD’s neutral wire
(white) to the system’s neutral connection.
2. Connect the SPD’s phase A and B wires (black) to
the system’s corresponding phase A and B
connections according to applicable national, state,
and local electrical codes.
Figure 3-1. 1/2 in. Locknut Mounting
See Figure 3-2. When mounting the SPD outdoors, use
weatherproof conduit and fittings to maintain the
enclosure’s NEMA 4 rating.

Installation and Operation
Operation
1. Apply system power. The LED should illuminate.
NOTE: If the connected LED does not illuminate, remove
power, check connections, and test again. If the LED still
does not light, contact an IASD.
2. The SPD will automatically begin to protect
downstream electrical devices from damaging
voltage transients.
With all phase voltages present, the LED indicator
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 turns OFF.
The unit is not repairable and contains no user
serviceable parts. If the unit fails, as evidenced by the
LED turning OFF, contact an IASD for a replacement.
IMPORTANT NOTE: Do not use the Suppression
Circuit Status LEDs as an indication of the presence
or absence of system phase voltages.
