Audible Noise The device background noise is negligible and does not restrict the location of

the installation.

Mounting The device is designed to be surface or flush mounted. Refer to the device

submittal drawings or the product catalog for typical mounting dimensions and weight.

Service Clearance The service clearance should meet all applicable code requirements.

Equipment Performance To obtain the maximum system performance, locate the device as close to the

circuit being addressed as possible to minimize the interconnecting wiring length. For every foot of wire length, approximately 160 Volts (6 kV / 3 kA, 8/20 microsecond) is added to the suppressed voltage. The Voltage Protection Rating (VPR) is located on the device nameplate and is measured six inches from the enclosure sidewall, according to UL 1449 test standards.

Electrical

Voltage Rating

ENGLISH

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Confirm the SPD voltage rating on the module or nameplate label is the same as the operating voltage.

Failure to follow these instructions will result in death or serious injury.

Prior to mounting the SPD, verify that the device has the same voltage rating as the power distribution system in which it is installed. Compare the nameplate voltage or model number on the SPD with the nameplate of the electrical distribution equipment.

The specifier or user of the device must be familiar with the configuration and arrangement of the power distribution system in which any SPD is to be installed. The system configuration of any power distribution system is based strictly on how the secondary windings of the transformer supplying the service entrance main or load are configured. This includes whether or not the transformer windings are referenced to earth via a grounding conductor. The system configuration is not based on how any specific load or equipment is connected to a particular power distribution system. See Table 1 for the service voltage of each SPD.

Grounding Rev. 04, 04/2020

Grounding

ENGLISH

HAZARDOUS TOUCH VOLTAGE

• Connect the Surge Protective Device ground terminal to the building grounding grid structure.

• Use an appropriately sized equipment grounding conductor.

• When using metallic raceway or conduit: — Do not use isolated bushings to interrupt the metallic raceway or conduit.

— Maintain electrical continuity at all raceway and conduit connections using

appropriate bonding devices.

• Do not use a separate isolated ground for the EMA Surge Protective Device.

• Verify proper equipment connection to the grounding system.

• Verify ground grid continuity by performing regularly scheduled inspections and testing as part of a comprehensive electrical maintenance program.

Failure to follow these instructions can result in death or serious injury.

General The EMA has SPD elements connected from phase to ground. It is critical that

there be a robust and effective connection to the building grounding structure. The grounding connection must utilize an equipment grounding conductor run with the phase and neutral (if present) connection of the power system.

For best over-voltage suppression by the EMA SPD, use a single-point ground system where the service entrance grounding electrode system is connected to, and bonded to, all other available electrodes, building steel, metal water pipes, driven rods, etc. (for reference, see IEEE 142-2007). The ground impedance measurement of the electrical system should be as low as possible, and in compliance with all applicable codes.

Power System Grounding

In addition to the power system configuration and voltage, the power system grounding method must be considered when selecting the appropriate EMA device. Refer to the following chart for information concerning the suitability of EMA device to specific power system grounding method.

Solidly-Grounded Power Systems

SPD DAMAGE AND POWER SYSTEM OVERVOLTAGE

• Do not connect devices rated for use on solidly-grounded power systems to resistance-grounded (for example, High Resistance Ground) or ungrounded power systems.

• Verify that the service entrance equipment is bonded to ground in accordance with all applicable codes.

• Verify that the neutral terminal of the power system transformer feeding the device is bonded to system ground in accordance with all applicable codes

Failure to follow these instructions can result in injury or equipment. damage

SPDs rated for use on solidly-grounded power systems must not be connected to resistance-grounded or ungrounded power systems. Such a connection can result in damage to the SPD.

Always verify the power system grounding configuration prior to application of power to the device. Confirm that all ground bonds are installed at both the service entrance equipment and power system transformer prior to application of power.

ENGLISH

.

Delta and Resistance-Grounded Power Systems

SPD DAMAGE AND POWER SYSTEM OVERVOLTAGE

• Ungrounded power systems are inherently unstable and can produce excessively high line-to-ground voltages during certain fault conditions. During these fault conditions any electrical equipment, including an SPD, may be subjected to voltages which exceed their designed ratings. This information is being provided to the user so that an informed decision can be made before installing any electrical equipment on an ungrounded power system.

• Resistance-grounded power systems must be maintained in an overdamped state to limit voltage overshoot and duration during operation.

• Verification and adjustment of correct power system damping should be done:

— Periodically as part of normal system maintenance. — Following power system modifications.

Failure to follow these instructions can result in injury or equipment damage.

The EMA product is intended for use on resistance-grounded power systems where the power system has been set for, and is maintained in, an over-damped state. For the power system to be over-damped, the current through the grounding resistor during a bolted phase-to-ground fault must be significantly greater than the total charging current of the system.

Periodic engineering evaluation of the power system is required to determine the worst-case charging current of the system and to adjust the grounding resistance accordingly. As the power system is modified, the value of the grounding resistor must be evaluated and adjusted to maintain the system in the over-damped state.

Operation

ENGLISH

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, CSA Z462 or NOM-029-STPS.

• This equipment must only be installed and serviced by qualified electrical personnel.

• Turn off all power supplying this equipment before working on or inside equipment.

• Always use a properly rated voltage sensing device to confirm power is off.

• Replace all devices, doors and covers before turning on power to this equipment.

• This equipment must be effectively grounded per all applicable codes. Use an equipment-grounding conductor to connect this equipment to the power system ground.

Failure to follow these instructions will result in death or serious injury.

LED Status Indicators The SPD diagnostic display panel shows the status of each MA module with

diagnostically controlled green/red LEDs (see Figure 16). If a unit is operating correctly, all of the phase LEDs will be illuminated green. To test the integrity of the diagnostics for each phase, push the button below the phase LEDs on the diagnostic display panel. The green LED will turn red and the alarm will sound, if the alarm is enabled. Releasing the test button will complete the test; the red LED will turn green and the alarm will shut off.

If an inoperable condition occurs on any phase, the audible alarm sounds and the corresponding phase LED on the diagnostic display panel is illuminated red. This indicates that the device needs service by qualified electrical personnel. The audible alarm can be silenced, until a qualified person is able to evaluate and service the SPD, by pressing the alarm enable/disable button. The alarm will silence and the green alarm LED will not be lit. The red phase LED will continue to be illuminated until the inoperative condition had been cleared.

On an MA module (see Figure 15), if either LED is not lit, the module should be replaced. If both green LEDs are not lit and the diagnostic display panel has power, then power has been lost to that phase or the module should be replaced (refer to Table 1 on page 6). Refer to the final equipment instruction bulletin for MA module disconnection and access instructions.

When power is applied to the SPD and one or more of the diagnostic display panel LEDs are red, and one or more MA module LEDs are out, the appropriate MA module should be replaced. Refer to “Maintenance and Troubleshooting” on page 27 for proper troubleshooting procedures and Table 4 for replacement modules.

For troubleshooting, call the Surgelogic Technical Assistance Group at 1-800-577-7353.

Audible Alarm Push the alarm enable/disable button to enable or disable the alarm (see

Figure 16). If the green alarm LED is lit the alarm is enabled. If the green alarm LED is not lit the alarm is disabled.

Surge Counter The surge counter displays the number of transient voltage surges since the

counter was last reset. The counter is battery powered to retain memory in the event of a power loss to the SSP module. To reset the surge counter, remove all power and press the small switch located inside the unit on the underside of the diagnostic circuit board near the RJ45 connectors (also refer to Figure 17). This will reset the counter to zero.

Dry Contacts

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Use 600 Vac rated dry contact wiring.

• Dry contact wiring must have less than 1/16 in. (1.6 mm) exposed wire from the dry contact block.

• Do not supply more than 24 V dc / 24 V ac and no more than a current of 2 A.

Failure to follow these instructions will result in death or serious injury.

FALSE INDICATION OF SURGE PROTECTION STATUS

Maintain at least 1.0 in. (25 mm) separation between dry contact wiring and the power wiring in the enclosure.

Failure to follow these instructions can result in equipment damage.

ENGLISH

The EMA series SPD is provided with dry contacts. The connection for the dry contacts is located on the back of the diagnostic display panel (lower right corner, refer to Figure 17). and will accept # 22–14 AWG stranded or solid wire. The dry contacts are three-position, Form “C” type with Normally Open, Normally Closed, and Common connections.

In the unpowered state the contact is closed between terminals NC and COM. This is also the alarm condition. The opposite state, closed between terminals NO and COM, indicates that power is on to the unit and that no alarm condition exists (See Table 5).

These contacts can be used for remote indication of the SPD’s operating status to a computer interface board or emergency management system. Also, these contacts are designed to work with the SPD remote monitor option described in the next section.

Care must be taken when installing the dry contact wiring because the terminals are on a moving door. Avoid the door hinge, any switches, and the high voltage areas of the enclosure when routing the wiring. To avoid the door hinge, tie wrap any dry contact wiring to the existing cable harness which crosses the hinge.

Higher energy applications may require additional relay implementation outside the SPD. Damage to the SPD relay caused by use with energy levels in excess of those discussed in this instruction bulletin are not covered by warranty.

Remote Monitor Option The remote monitor option has two LEDs, one red and one green, and an

audible alarm with an enable/disable switch. Normal status is a lit green LED, and no audible alarm. To test the integrity of the remote monitor, press the pushto-test switch. If the alarm is enabled, the green LED will turn off, the red LED will turn on, and the alarm will sound. Releasing the switch will complete the test; the red LED will turn off, the green LED will turn on and the alarm will shut off.

If suppression on any phase is lost, the green LED will turn off, the red LED will turn on and an alarm will sound. The audible alarm can be silenced by pushing the alarm enable/disable button. The alarm will silence and the green alarm LED will not be lit. The red LED will continue to be illuminated until the inoperative condition has been cleared.

The remote monitor includes a 120 Vac to 12 Vdc adapter with a six-foot power cord. Connections are made to the SPD diagnostic panel with Form “C”, 3-position dry contacts (provided) and the appropriate length of solid or stranded # 22–14 AWG wire up to 1000 ft. (305 m), not provided.

Conexión a tierra

TENSIÓN PELIGROSA AL TOQUE

• Conecte la terminal de tierra del SPD a la estructura de la red de puesta a tierra del edificio.

• Utilice un conductor de puesta a tierra del equipo de tamaño apropiado.

• Cuando se usa tubo conduit o canalización metálica: — No utilice pasamuros aislados para interrumpir el tubo conduit o

canalización metálica.

ESPAÑOL

— Mantenga continuidad eléctrica en todas las conexiones de la canalización

y tubo conduit empleando dispositivos de conexión apropiados.

• No utilice una conexión a tierra aislada independiente para el dispositivo EMA.

• Revise las conexiones al equipo y asegúrese de que esté correctamente conectado al sistema de puesta a tierra.

• Verifique la continuidad de la red de puesta a tierra realizando inspecciones y pruebas como parte de un programa completo de servicio de mantenimiento eléctrico.

El incumplimiento de estas instrucciones puede causar la muerte o lesiones serias.

Generalidades El dispositivo EMA tiene elementos del SPD conectados de fase a tierra. Es

fundamental que exista una conexión robusta y eficaz a la estructura de tierra del edificio. La conexión de puesta a tierra debe utilizar un tendido de conductores de puesta a tierra del equipo con la conexión de fase y neutro (si la hay) del sistema de alimentación.

Para obtener una mejor supresión de sobretensión del SPD tipo EMA, utilice un sistema de conexión a tierra de un solo punto en el que el sistema de electrodo de puesta a tierra de acometida esté conectado y unido a todos los demás electrodos disponibles, a un elemento de acero, tubería de agua de metal, varillas de accionamiento, etc. (consulte la norma 142-2007 del IEEE para obtener referencias). La medición de impedancia de conexión a tierra del sistema eléctrico deberá ser lo más baja posible y deberá cumplir con todos los códigos aplicables apropiados.

Puesta a tierra del sistema de alimentación

Además de la configuración y tensión del sistema de alimentación, el método de puesta a tierra del sistema debe considerarse al seleccionar el dispositivo EMA apropiado. Consulte la siguiente tabla para obtener información al seleccionar el dispositivo EMA apropiado para la puesta a tierra específica del sistema de alimentación.

Sistemas de alimentación sólidamente puestos a tierra

DAÑO AL SPD Y SOBRETENSIÓN EN EL SISTEMA DE ALIMENTACIÓN

• No conecte los dispositivos diseñados para usarse en sistemas de alimentación sólidamente puestos a tierra en sistemas de alimentación no puestos a tierra o con alta resistencia a tierra (por ejemplo, HRG).

• Asegúrese de que el equipo de acometida esté conectado a tierra de acuerdo con todos los códigos y normas correspondientes.

• Asegúrese de que la terminal de neutro del transformador del sistema de alimentación que alimenta al dispositivo esté conectada a la tierra del sistema de acuerdo con todos los códigos y normas correspondientes.

El incumplimiento de estas instrucciones puede causar lesiones personales o daño al equipo.

Los SPD diseñados para usarse en sistemas de alimentación sólidamente puestos a tierra no deben ser conectados a sistemas de alimentación no puestos a tierra o con alta resistencia a tierra. Dicha conexión puede causar daño al SPD.

Siempre verifique la configuración de puesta a tierra del sistema de alimentación antes de energizar el dispositivo. Asegúrese de que todas las conexiones a tierra hayan sido instaladas en ambos, el equipo de entrada de acometida y el transformador del sistema de alimentación, antes de energizar.

ESPAÑOL

Sistemas de alimentación con resistencia a tierra y delta

DAÑO AL SPD Y SOBRETENSIÓN EN EL SISTEMA DE ALIMENTACIÓN

• Los sistemas de alimentación sin conexión a tierra son inherentemente inestables y pueden producir tensiones excesivamente altas de línea a tierra durante ciertas condiciones de falla. Durante estas condiciones de falla cualquier equipo eléctrico, incluyendo un SPD, puede ser sometido a tensiones que excedan sus valores nominales para los cuales fueron diseñados. Esta información se proporciona al usuario para que puede tomar decisiones informadas antes de instalar cualquier equipo eléctrico en un sistema de alimentación sin conexión a tierra.

• Los sistemas de alimentación con resistencia a tierra deben mantenerse en un estado de sobreamortiguación para limitar la duración y el exceso de tensión durante el funcionamiento.

• Es necesario realizar la verificación y ajuste correcto de amortiguación del sistema de alimentación:

— Periódicamente y como parte de un servicio de mantenimiento normal. — Después de realizar modificaciones al sistema de alimentación.

El incumplimiento de estas instrucciones puede causar lesiones personales o daño al equipo.

El dispositivo EMA se usa en sistemas de alimentación con resistencia a tierra donde el sistema ha sido ajustado para mantenerlo en estado de sobre amortiguación. Para que el sistema de alimentación se mantenga en sobre amortiguación, la corriente directa de la resistencia de puesta a tierra (durante una falla franca de fase a tierra) debe ser significativamente mayor que la corriente total de carga del sistema.

Para obtener asistencia de diagnóstico de problemas, póngase en contacto con el grupo de asistencia técnica Surgelogic llamando al 1-800-577-7353 (en EUA) o bien al 01-800 72 463 4337 (en México).
