The Emerson Network Power 430 & 440 Surge Protective Devices are high quality, high energy
surge current diversion system designed to protect sensitive equipment from damaging
transient voltage surges resulting from load switching, lightning strikes and other sources.
The installer should perform the following steps to assure a quality installation. Please read all
instructions before starting the installation of this product. These instructions do not replace
national or local electrical codes — check applicable codes to ensure compliance.
INSTALLATION
DANGER! ONLY QUALIFIED PERSONNEL SHOULD INSTALL
OR SERVICE THIS SYSTEM. ELECTRICAL SAFETY PRE-
CAUTIONS MUST BE FOLLOWED WHEN INSTALLING OR
SERVICING THIS EQUIPMENT. TO PREVENT RISK OF ELECTRICAL SHOCK, TURN OFF AND
LOCK OUT ALL POWER SOURCES TO THE UNIT BEFORE MAKING ELECTRICAL
CONNECTIONS OR SERVICING.
DANGER! SEULEMENT LE PERSONNEL QUALIFIÉ DOIT INSTALLER OU MAINTENIR CE
SYSTÈME. DES PRÉCAUTIONS DE SÉCURITÉ EN ÉLECTRICITÉ DOIVENT ÊTRE SUIVIS LORS
DE L'INSTALLATION OU DE LA MAINTENANCE DE CET EQUIPEMENT. POUR EVITER TOUT
RISQUE DE CHOC ÉLECTRIQUE, DÉBRANCHEZ ET VEROUILLER TOUTES LES SOURCES D’
ALIMENTATION DE CET EQUIPEMENT AVANT DE LE BRANCHER OU LE MAINTENIR.
Environment — The unit is designed for operation indoors in ambient temperatures of 40ºC (-40ºF) to +85ºC (+185ºF) with a relative humidity of 0% to 95% (non-condensing). The
unit is provided in an industrial enclosure, which should not be installed in areas with excessive
dust, corrosive vapors, flammable materials or explosive atmospheres.
Mounting — Mount unit as close as possible to the service panel in close proximity to the
breaker that will feed the SPD. For best performance, unit should be positioned so that the
length of the wiring to the surge protective device (SPD) unit is minimized. Dimensional
information is shown on page 5-6.
NEMA 4X (Non-Metallic) enclosure - Remove cover on unit to gain access to the
mounting holes in case. Use #6 x 3/4” self-threading screws (provided), to mount the SPD
to wall or back plane. Replace cover on unit and torque cover screws to 10 IN-LBS, (see
drawing).
NEMA 12/4, (Metallic) enclosure – Mounting flanges accept 1/4 hardware.
Wire Sizing/Routing —To reduce the wiring impedance to surge currents, the phase, neutral
(if required), and ground conductors are recommended to be twisted together and routed in
the same raceway (conduit). Avoid any sharp bends in the conductors. All wiring must comply
with the National Electrical Code (NEC) and applicable local codes.
Conduit Connection — The SPD wires should feed through the plastic conduit piece supplied.
The conduit should be cut to match the distance from the unit to electrical panel. Use the
supplied conduit hub to connect to the electrical panel.
Wiring Connections — Before making connections to the unit, verify that the unit model
number and nameplate voltage rating are appropriate for connection to the intended power
source (See table).
1. It is recommended that a 20A circuit breaker be used for installation and connection to the
service panel.
2. Connect a white wire from the supply neutral to the neutral terminal/lug inside the SPD,
and connect a green wire from the source ground to the SPD ground terminal/lug.
3. Connect a black phase wire from each line on the service panel/circuit breaker to each
corresponding phase terminal/lug in the SPD.
4. If using remote sensing (Form C dry contact), connect wires to COM (orange), NC (blue),
and NO (yellow) respectively. Relay’s maximum switching capacity is 250VAC, 5A.

CAUTION – For proper and safe operation, neutral and
ground MUST be reliably connected. Failure to operate this
unit from a solidly grounded power source of the proper
2
configuration will reduce or impede operation, and may result in unit failure.
ATTENTION - Pour un fonctionnement correct et sûr, le neutre et la mise à la terre doit
être connectés de manière fiable. Défaut de faire fonctionner cet appareil à partir d'une
source d'alimentation solidement mise à la terre va réduire ou même empêcher le
fonctionnement correct et peut entraîner une défaillance de l'unité.
Applying Power — Apply power to the SPD and assure status indications are normal. Under
normal conditions, the green “OK” or “PHASE” LED(s) are illuminated and the red “REPLACE”
or “SERVICE” LED is OFF. If normal status indication does not exist, see “TROUBLESHOOTING”.
PRODUCT RATINGS AND LIMITATIONS
Voltage Protection Rating – To obtain the voltage protection ratings (VPRs), as obtained by
Underwriters Laboratories, Incorporated, in accordance with the Standard for Safety, Surge
Protective Devices (SPDs), Standard 1449 Third Edition, released 2009, marked on this product,
#12 AWG wire must be utilized to connect the 430/440 SPD to your facilities’ power grid.
Connections made with conductors other than #12 AWG may result in different VPRs.
Circuit Ampacity Limitations – This device has been investigated by Underwriters
Laboratories, Incorporated to withstand, without exposing live circuits or components on
power sources, a voltage of two times (2x) the device ratings, and fault currents of up to
200,000 AIC, as described in the Standard for Safety, Surge Protective Devices (SPDs), Standard
1449, Third Edition, released 2009.
TROUBLESHOOTING
If any of the diagnostic indicators indicates a problem (i.e. red LED ON, and/or green LED(s) OUT;
and/or alarm sounding), check all connections and voltages to the unit. If all connections are reliable,
and proper voltages are supplied to the unit, call Emerson Network Power Surge Protection, Inc at
607-721-8840.
N-G Overvoltage Indication – If all green “PHASE” LEDs are ON and red “SERVICE” LED is also ON this
indicates that the neutral to ground voltage at the connected panel may be 20 VAC or higher.
