Measured Limiting Voltage (MLV) Test Parameters: Positive polarity, Category A: Line power applied, Category C: No line power applied, Voltages are peak (±10%). Measured Limiting Voltages are
measured from the insertion point on the sine wave to the peak of the surge for powered tests. Each MLV is the average of the phases within that mode of protection. In order to duplicate the results, the
specified mode of protection must be tested in all phases (except N-G) and averaged together. (Individual mode or shot results may vary by more than 10%. Scope Settings: Time Base = 10 microseconds
per division, Sampling Rate = 2.5 Gigasamples/sec, Bandwidth = 400 MHz (200 MHz for Cat C), Probes: Tektronix P5100/P6015A. These settings help to assure MLV results are accurate). All tests
performed with 6” lead length (external to the enclosure), simulating actual installed performance. The MLVs reported above are certified by Third-Party, Independent Testing. Individual test
reports are available upon request.
†The MLV reported for the Category C High, 10 kA 8/20 Current Driven Test is determined by measuring the MLV of one of the fifteen 10 kA impulses impressed through the SPD during the Nominal
Discharge Current (In) Test from C62.62TM-2010 and ANSI/UL 1449 (4th Edition). This is not the MLV recorded during the pre- and/or post-test 6 kV / 3 kA Combination Wave Test used to determine the
VPR of the SPD. The VPRs are reported on page 1 of this specification.

WARNING - HAZARDOUS VOLTAGES ARE PRESENT. Improper installation may result in serious injury to the installer and/or damage to the
electrical system or related equipment. Read all instructions before beginning the installation. Safety equipment must be used as prescribed by OSHA,
whenever working around hazardous voltages.
Failure of unit and/or consequential equipment damage due to improper installation or misapplication is not covered by the product
warranty.
Voltage measurements and installation must be completed by a licensed/qualified electrician in accordance with the National and/or Canadian
Electric Code, State, and Local codes. These requirements supersede this instruction.
POWER MUST BE REMOVED FROM THE ELECTRICAL SYSTEM BEFORE INSTALLING THE UNIT.
INSTALLATION MATERIALS REQUIRED
The following is a list of materials that may be needed for proper installation of this Surge Protective Device (SPD). This list is intended to help the installer anticipate
materials needed for a successful installation. The installer should become familiar with the scope of work to avoid lost time and improper installation. Failure to use fittings
that are “Listed”will void the “Listing” of the SPD.
For Splices: 3 (or more) cable taps; such as: NSI IPCS- 2001 or 7501 (per Code).
Attachment Hardware: Use (four) screws or anchor toggle bolts, flat washers and lock washers.
¾” hub (included with most models).
Tools: Drill & bits, Mechanical Knock out Set, Channel Locks™, Level, Screwdrivers, Appropriate Safety Equipment.
WIRING DIAGRAM
This device is suitable for use on a circuit capable of delivering not more than 200,000 RMS symmetrical
Amperes, for the respective models’ (max.) nominal voltage shown in the Table of Maximum Suggested
Operating Voltages on page 2.
The SPD is equipped with integral fuses. This allows the device to be installed directly to the system bus
bars, to the main lugs in a panel or disconnect, or to a circuit breaker. Consult NEC/CEC, State and
Local Codes to assure compliance†.
In the event that one or more of the LED status indicators fail to illuminate, the entire device should be
returned for warranty replacement. If service of the device is a consideration (i.e: removal and
replacement), and there is no means to remove power from the SPD without removing power from the
entire system, the installer may consider incorporating a disconnect device between the SPD and the
system connecting point.
The design of these units provides superior protection for sensitive/critical equipment connected to
distribution panels, sub-distribution panels or individual equipment disconnects. These units are
designed for use at IEEE C62.41 Location Categories A, B, and C. “Voltage Responsive” type units are
designed to be used in 50 to 420 Hz applications. NOTE: SPDs with model numbers beginning with the
letter “C” are “Frequency Responsive” (sine wave tracking) units and are designed to be used in 50 to 60
Hz applications only and shall not be used at locations where the voltage frequency fluctuates (i.e.: on
the output of variable frequency drives).
When inspecting the panel prior to installation, insure that a proper safety ground is present as required
by the NEC/CEC.
Note: Pre-existing breakers of the rated load size (30 amp, etc.), that are serving existing loads, may be
utilized if the breaker is “Listed” for this application (see NEC) and provided the owner/tenant has
authorized multiple conductor termination.

NOTE FOR ISOLATED GROUND
If the electrical system uses an isolated ground, connect the SPD ground to the isolated ground bus. EXCEPTION FOR METAL ENCLOSURES AND/OR METALLIC
HUBS –For metal enclosures and/or metallic hubs, the SPD ground wire is bonded to the enclosure internally. If the system uses an isolated ground, the SPD enclosure
must be isolated from the panel or load it is being connected to through the use of an insulated conduit fitting or other “Listed” fitting. In this installation, the ground wire
from the SPD must terminate at the isolated ground bus.
BEFORE INSTALLATION
For proper performance, the SPD must be installed with the shortest lead length possible. Sharp bends should be avoided.
No position-oriented components are used in the units. Devices can be mounted upside down or sideways allowing for shortest possible lead lengths.
There are a few basic principles for surge suppression installation. They are:
1. For proper performance, the SPD must be installed with the wires as short and straight as humanly possible. Any sharp bend in the wire is unacceptable!
This applies to phase, neutral, and ground leads. The objective is to reduce the lengths of wire provided on each unit, not add to it. The priority is to the
phase leads, then the neutral, and then the ground lead.
2. Install the SPD on the side of the panel closest to the neutral bus, if present, and use a breaker on the same side.
3. Use a breaker close to the neutral bus and the SPD to keep the wires as short and straight as humanly possible.
4. The ground wire may be connected to the panel by using a ground lug installed near the SPD in the can or frame as they are grounded. (See exception
above for Isolated Grounds).

INSTALLATION STEPS (NOTE: 3N6 and 3N7 Models must be connected in A, B, C Phase rotational sequence to the electrical system.)
STEP 1: Check Voltages
Confirm that the nominal system voltage does not exceed the maximum suggested operating voltage for the model to be installed according to the Table above. All
voltage measurements should be completed with a RMS voltmeter. DO NOT INSTALL THE FUSED UNIT IF THE MEASURED VOLTAGE EXCEEDS THE
MAXIMUM SUGGESTED OPERATING VOLTAGE OF THE DEVICE.
CAUTION: Do not proceed further until power has been removed from the electrical system.
STEP 2: Mounting the Unit
Non-lug type SPDs are provided with 18-24 inches of #10 AWG/TEW stranded wire. For best performance, mount the SPD so that all wires can be cut and connected in
the shortest, straightest path possible, the goal being 6 inches of wire length or less. For every inch of conductor longer than 6-inches, you increase the let-through voltage
of the SPD by 21.7 volts for an ANSI/IEEE Category B, 6kV, 3kA impulse.
No sharp bends should be made in the installation. If bends are unavoidable, make them smooth and flowing. The device contains no position-dependent
components; therefore, the device can be mounted upside down or sideways.
Do not cut any wires until suppressor has been mounted. Units with plastic hubs must be installed with the non-metallic flexible conduit and extra hub.
While holding the SPD on the wall, determine the shortest, straightest distance between the hub on suppressor and hub to be installed on panel. Cut the flexible
conduit to shortest length possible to fit securely over both hubs.
Twist the trimmed flexible conduit onto the extra hub. Slide conduit and hub over wires of the SPD and twist the conduit onto the hub of the SPD.
Connect the extra hub to the panel and mount the SPD to the wall.
STEP 3: Connecting “Optional Form C” Dry Relay Contacts (Applies only to SPDs with optional Dry Relay Contacts)
Make sure power is removed from surge suppressor.
Open surge suppressor lid and note encapsulant height prior to drilling or punching enclosure. (Allow internal clearance for locknuts).
Drill 0.5” diameter clearance hole through side, top or bottom of unit and install a watertight strain relief (i.e.: Altech #225-A00 (Part No. SR011).
NOTE: Surge suppressor is equipped with two sets of contacts. The first set (labeled 1 & 2, N/C) is normally closed and the other set (labeled 3 & 4, N/O) is
normally open with power applied.
Contacts are rated at 60 W (from 30 VDC @ 2 A to 150 VDC @ 0.4 A) or 100 VA (from 50 VAC @ 2 A to 220 VAC @ 0.45 A).
Alarm contacts accept AWG #26 (0.14mm2) to AWG #16 (1.5mm2) wire. Wire size must be in compliance with NEC/CEC, State or Local codes for power on circuit.
Follow rules for the class of wiring used when routing alarm leads. To maintain NEMA-4 (IP66) rating use appropriate cable and watertight strain relief.
Connect alarm circuit(s) to Normally Open (N/O) or Normally Closed (N/C) terminals as required.
Upon replacing front cover of suppressor, certain models allow various lid rotations (90° to 180°) for improved label orientation. (model specific)
STEP 4: Wire the SPD into the Electrical System
Carefully lay out the wires keeping them as short and straight as possible. (Wires may be slow-twisted together thereby reducing RF-impedance.) After a satisfactory
layout has been made to the appropriate termination points as described below, cut the wires and connect them as instructed.
Connect the GREEN ground wire from the SPD to the system ground bus bar or to a lug mounted in the can or frame close to the SPD if the Ground bus bar is not
close following the current NEC/CEC. Refer to earlier sections for systems utilizing an isolated ground.
Connect the phase wires or “hot” wires (see table above for wire colors) from the SPD to the phase conductors or buses of the electrical system through the required
circuit interrupts (fuses or breakers) described above. Note that the SPD has internal fusing and does not require external circuit interrupts (external fuses or
breakers). The Phase conductors may be directly connected to the phase conductors or buses after the main disconnect.
Upon replacing front cover of suppressor, certain models allow various lid rotations (90° or 180°) for improved label orientation (< model specific).
Before energizing, measure the voltage again to ensure it is within the levels in the table above.
Immediate failure of the SPD will occur if installed on voltages higher than shown in the Table at the top of this page.
STEP 5: Apply Power to the Surge Suppressor
The LED indicators should be illuminated. If not, remove power from the SPD and contact Surge Suppression, LLC at: 1-(888)-987-8877.
