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.

Product Usage Instructions
Installation
Before installation, it is important to read the manual thoroughly to ensure proper installation and prevent hazards. The device should be mounted and wired by a trained and licensed electrician. 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
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.
Mounting
The Surge Protection Device should be mounted in a location that is easily accessible for maintenance and inspection. The device should be mounted in a vertical position with the top of the device facing up. It should be mounted using the provided mounting holes and screws.
Wiring
The device should be wired by a trained and licensed electrician in accordance with local codes and regulations. The device should be connected to the electrical system through a dedicated circuit breaker. The wiring should be checked for proper connections and insulation before energizing the device. SPD can be mounted directly to the electrical panel or service equipment
- Choose a mounting location for the SPD that provides the shortest and straightest possible wiring (lead length) from SPD to electrical system connections. Excessive lead length and sharp bends will degrade SPD performance.
- When installing SPD as a Type 2 SPD, SPD’s wire leads are required to be terminated to a dedicated 2-pole 20 amp circuit breaker. Circuit breaker must be approved for installation and use in the panelboard by the panelboard manufacturer.
- Or, use appropriate screws to mount SPD to surface and use conduit to connect SPD to electrical panel.
- See Figure 3-2. When using conduit, avoid using 90° elbows (A) and keep conduit run as short and straight as possible (B).
When installing wiring:
- Follow all national, state, and local electrical codes when making wiring connections.
- When connecting wires from SPD to electrical system, cut wires as necessary to keep them as short as possible.
- To maximize SPD’s performance, twist and bind wires together to reduce impedance of wire (one twist/inch).
- See Figure 3-3. Connect SPD’s neutral wire (white) to system’s neutral connection
- Connect SPD’s phase A and B wires (black) to 2-pole 20 amp circuit breaker in electrical panel, and torque circuit breaker terminals to the manufacturer’s required torque settings.
Conduit Installation
See Figure 3-1. Mount SPD directly to electrical panel using a 1/2 in. locknut
See Figure 3-2. When mounting SPD outdoors, use weatherproof conduit and fittings to maintain the enclosure’s NEMA 4 rating
Operation
Once the device is properly installed, it will protect against electrical surges. It is important to regularly inspect and maintain the device to ensure its proper operation. Refer to the manual for further information on maintenance and inspection.
-
Apply system power. LED should illuminate.
NOTE : If connected LED does not illuminate, remove power, check connections, and test again. If LED still does not light, contact an IASD. -
SPD will automatically begin to protect downstream electrical devices from damaging voltage transients.
With all phase voltages present, 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 LED turns OFF. Unit is not repairable and contains no user serviceable parts. If unit fails, as evidenced by 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
