Surge Protective Device (SPD)

Qualified Person

For the purpose of this instruction leaflet, a qualified person:

1. is familiar with the subject equipment and the hazards involved

with their application, use, administration and maintenance.

2 is trained and authorized to de-energize, clear, ground, and tag

circuits and equipment in accordance with established safety

practices.

3 is trained in the proper care and use of personal protective

equipment such as rubber gloves, hard hat, safety glasses or face

shields, arc-flash clothing, etc., in accordance with established

safety practices.

4 is trained to render first aid.

5 has received safety training to recognize and avoid the hazards

involved.

6 has the skills and knowledge pertaining to the construction and

operation of this equipment and its installation.

Installation Instructions

IMPORTANT:

IMPORTANT:IMPORTANT: Read these instructions carefully to assure proper

installation and assembly. Ensure all fasteners and connections are

properly tightened. Installation in a manner inconsistent with these

instructions will void warranty.

To ensure integrity of the finished installation, do NOT install the

SPD if it has been dropped or abused during the installation

process.

The SPD contains no user serviceable parts and cannot be

repaired. Performing the following will compromise the unit’s performance

and will void the warranty. Do NOT:

• Megger or IR (Insulation Resistance) test the system with the SPD installed

• Install in a system that has a voltage greater than the unit’s rated voltage

Ungrounded power systems are inherently unstable and can produce

excessively high line- -ground voltages during certain fault conditions. During to

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.

Safety Concerns

This instruction sheet is not comprehensive. It is assumed

the S installer will follow trade and NEC 70E established PD

safety precautions for working in an electrical environment.

• Suitable for use on a circuit capable of delivering not more

than 200,000 RMS symmetrical amperes at the nominal

system voltage.

• This device features internal protection that will disconnect

the surge protective component at the end of its useful life

but will maintain power to the load - now unprotected. If

the situation is undesirable for the application, follow the

manufacturer’s instructions for replacing the device.

• The LED status indicators report the status of the

protection circuitry.

• Contains no serviceable parts

• Warning - Shock Hazard - Do not open

Required Additional Materials: To maintain outdoor and liquid-tight

ratings, the Myers hub (conduit fitting) installed on the SPD should be

utilized in conjunction with the sealing washer and chase nipple provided.

The sealing washer is placed between the Myers hub and wall of the

panelboard or enclosure to which the SPD is to be installed. Further, it is

recommended that thread seal tape (aka “Teflon tape”) be used to wrap the

threads of the chase nipple before installation in addition to using the

sealing washer. If other conduit connections are used in place of the

provided hardware, follow the manufacturer’s instructions on maintaining a

liquid tight seal on the connections.

1. Inspect the unit to determine if the unit:

• has the correct nominal system and Maximum Continuous

Operating Voltage (MCOV) ratings and is the correct configuration for

the installation site. (See Table 1 for specifications), it is required that

the power system voltages be verified with the appropriate meter prior

to installation and those values confirmed to be lower than the MCOV.

Use Table 2 to record your readings and verify the recorded values are

lower than those listed in Table 1 for the unit.

• is NOT damaged, do not attempt to install if it is damaged. Obtain a

proper replacement before proceeding with the installation.

2. De-energize the electrical panel or equipment and follow the established

lockout / tagout procedures. Confirm the location is de-energized using the

appropriate test equipment before proceeding with the SPD installation.

3. Select a location on the panel or equipment that allows the SPD leads to

reach their intended connection points using the shortest possible lead

lengths. A dedicated multipole breaker is recommended.

4. Remove a knockout sized for, or make an appropriate sized hole for the

conduit hub where the SPD is to be mounted. For an outdoor or liquid-tight

installation, follow the instructions provided in the CAUTION statement

above.

5. Remove the chase nipple from the Myers hub attached to the SPD.

Mount the SPD to the panelboard or enclosure by routing the wires from

SPD though the sealing washer (if outdoor or liquid-tight installation is

needed) and then open knockout or hole into the panel. On the inside of the

panel or enclosure, route the wires though the threaded end of the chase

nipple. Thread the chase nipple into the Myers hub and tighten so that the

SPD is mechanically attached to the panel enclosure. Be careful not to or

damage the insulation of the wires during the mounting process. If the

sealing washer is used, be sure it is not damaged or displaced by the Myers

hub and it maintains a liquid- ght seal. The mounting feet provided with the ti

SPD can also be used to aid in mechanically mounting the SPD as

necessary.

6. Cut the leads to the shortest possible length to reach the connection

point (i.e. breaker or grounding bar). Trim the insulation of the leads so that

they can be connected appropriately (review manufacturer’s instructions for

terminating to the breaker or grounding bar as needed). The shorter the

SPD leads, the better the SPD will protection against surges.

7. Twist the phase conductors and avoid sharp bends (NEC Art 285.12).

Make electrical connections appropriate for the application (see Power

System Diagrams). If your electrical system is not represented in the circuit

diagrams, contact manufacturer. Tighten the electrical terminals to the

terminal manufacturer’s specifications.

8. Energize panel or equipment and verify the LED status indicator is ON

(Blue).

Contacts

• NOTE: SPD is equipped with sets of colored 18 to 22 AWG wires.

Blue = Common, Orange = N/C, Yellow = N/O when power is applied.

(SPDT; Form C)

• Contacts are rated at ≤60 W/125 VA (from 30 VDC @ 2 A to 150

VDC @ 0.4 A), max. switched current = 2 A.

• Follow rules for NEC class 2 wiring when routing alarm leads. To

maintain NEMA-4X (IP65) rating use appropriate cable and liquid

tight strain relief if needed (user supplied)

• Connect alarm circuit(s) to Normally Open (N/O) or Normally

Closed (N/C) circuits as required.

• If not using these contacts, please cap off the wires with a UL

Listed wire nut.
