WARNINGS
Safety First - Hazardous Voltage & Shock Hazard •
Only qualified licensed electricians should install or service SPDs •
Hazardous voltages exist within SPDs •
SPDs should never be installed or serviced when energized •
Use appropriate safety precautions including Personal Protection Equipment •
Failure to follow these instructions can result in death, serious injury, and/or equipment damage •
This manual shall be read in its entirety prior to installing •
Bonding and Grounding Hazard
Verify that the neutral conductor in the service entrance equipment is bonded to ground in accordance with the
National Electric Code (NEC®) and all applicable codes. During installation into an electrical system the SPD must
not be energized until the electrical system is completely installed, inspected and tested. All conductors must be
connected and functional including the neutral (if required). The voltage rating of the SPD and system must be
verified before energizing the SPD. Failure to follow these guidelines can lead to abnormally high voltages at the
SPD. This may cause the SPD to fail. The warranty is voided if the SPD is incorrectly installed and/or if the neutral
conductor in the service entrance equipment or downstream of separately derived systems is not bonded to
ground in accordance with the NEC®.
Do Not Hi-Pot Test SPDs
Any factory or on-site testing of power distribution equipment that exceeds normal operating voltage such as
high-potential insulation testing, or any other tests where the suppression components will be subjected to higher
voltage than their rated Maximum Continuous Operating Voltage (MCOV) must be conducted with the SPD
disconnected from the power source. For 4-wire systems, the neutral connection at the SPD must also be
disconnected prior to performing high-potential testing. Failure to disconnect SPD and associated components
during elevated voltage testing will damage the SPD and will void the warranty.
SPDs on Ungrounded Systems
Caution - Ungrounded 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. An SPD designed specifically for Ungrounded systems
should be used.

Unpacking & Preliminary Inspection
Inspect the entire shipping container for damage or signs of mishandling. Remove the packing materials and
further inspect the unit for any obvious shipping damages. If any damage was found and is a result of shipping or
handling, immediately file a claim with the shipping company and forward a copy to nVent.
Storage Environment
This SPD should be stored in a clean, dry environment. Storage temperature range is -35°C (-31°F) to +75°C
(+167°F). Avoid exposure to high condensation
PRE-INSTALLATION & INSTALLATION PLANNING
Operating Environment
The standard unit uses a Type 4 enclosure. Before installing, ensure that your enclosure type and application are
appropriate with regard to moisture, dirt, excessive dust, flammable materials or atmospheres, corrosive vapors,
etc. Please consult factory if enclosure needs to be changed. This SPD is designed in an ambient temperature range
of -35°C (-31°F) to +75°C (+167°F) with a relative humidity of 0% to 95% (noncondensing). Excessive temperature
may inadvertently operate internal thermal overtemperature protectors.
Line Side versus Load Side Installation
The SES360 & SES480 series are tested and qualified as either Type 1 or Type 2 SPDs per UL 1449 Fifth •
Edition. Type 1 SPD can be installed on the Line Side of the service overcurrent device. Type 1 SPDs may also
be installed in Type 2 applications. As a generalization, it is more practical to install as Type 2 on load side of
main overcurrent device for maintenance reasons.
Audible Noise
SPD background noise is negligible or non-existent, and does not restrict the location of installation.
Lead Lengths & Maximizing SPD Performance
SPDs must be located as close to the circuit as possible to minimize parasitic losses. Use the shortest & straightest
possible leads. Pre-Plan installations and ensure that nearest breaker positions are used. If new construction,
adjust breaker locations as appropriate. When longer leads are unavoidable, gently twist leads together (one to
two twists per foot), or tie-wrap leads together.
Voltage Rating
Before installing SPD, verify that it has the same voltage rating as the power distribution system. Compare the
SPDs nameplate voltage or model number and ensure that SPD configuration matches the intended power source.

Circuit Breaker Connected
When connected on load side of main disconnect, we suggest connecting via a 60-125A circuit breaker. The circuit
breaker is the intended disconnect switch and provides short circuit protection to the connecting conductors. These
SPDs have internal overload protection elements within the product. These SPDs have demonstrated 200kA Short
Circuit Current Ratings (SCCRs).
System Grounding
An equipment grounding conductor must be used on all electrical circuits connected to the SPD. For the best
performance, 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 Std 142-2007). For sensitive electronics and computer systems, we recommend that the ground impedance
measurement be as low as possible. When metallic raceway is used as an additional grounding conductor, an
insulated grounding conductor should be run inside the raceway. Adequate electrical continuity must be maintained
at all raceway connections. A separate isolated ground for the SPD is NOT recommended. Proper equipment
connections to grounding system and ground grid continuity should be verified via inspections and testing on a
regular basis as part of a comprehensive electrical maintenance program. On 4-Wire Power Systems, neutral to
ground bonding (Main Bonding Jumper) must be installed per the NEC®. Failure to do so WILL damage SPDs.
UL 1283 required language concerning the installation of EMI Filters
a) An insulated grounding conductor that is identical in size and insulation material and thickness to the
grounded and ungrounded circuit supply conductors, except that it is green with or without one or more
yellow stripes, is to be installed as part of the circuit that supplies the filter. Reference should be made to
Table 250-122 of the National Electrical Code regarding the appropriate size of the grounding conductor.
b) The grounding conductor mentioned in item a is to be grounded to earth at the service equipment or other
acceptable building earth ground such as the building frame in the case of a high-rise steelframe structure.
c) Any attachment-plug receptacles in the vicinity of the filter are to be of a grounding type, and the grounding
conductors serving these receptacles are to be connected to earth ground at the service equipment or other
acceptable building earth ground such as the building frame in the case of a high-rise steel-frame structure.
d) Pressure terminal or pressure splicing connectors and soldering lugs used in the installation of the filter shall
be identified as being suitable for the material of the conductors. Conductors of dissimilar metals shall not be
intermixed in a terminal or splicing connector where physical contact occurs between dissimilar conductors
unless the device is identified for the purpose and conditions of use.
Retro-fit Into Existing Panel with No Available Breaker Positions
Follow all applicable Codes:
Consider consolidating loads in a manner that might free breaker positions.
A ten foot tap rule in NEC® 240.21(B)(1) allows you to tap the bus as long as the tap conductors are rated at least
10% of the ampacity of the panel. In the case where the ampacity of the panel is larger the wires of the SPD,
consider tapping the bus per NEC® 240.21(B)(1) and running appropriate size conductors to a safety switch fused to
60-125A. Mount the SPD immediately adjacent to the safety switch.
