PanelMax™ Shielded Wiring Duct and Noise Shield route, separate, and shield

sensitive wiring from noise emission. This allows pathways to be placed in

closer proximity, saving valuable space within industrial control panels. The

shielding provides up to 20dB reduction in noise (EMI/RFI), or 90% noise

voltage reduction (NVR), which is equivalent to 6 inches of air spacing

between sensitive and noise-emitting wiring.* **

Several wire routing and segregation configurations are possible with the

innovative Shielded Wiring Duct and Noise Shield, delivering greater

design flexibility to satisfy a wide range of applications.

These products are part of the broad range of reliable product systems

offered by the Panduit Industrial Automation Solution. These product

systems aid in reducing design and assembly time, create valuable panel

space savings, and provide easier installation and maintenance.

Key Features Benefits

Metal noise barrier* **^‡ Reduces EMI/RFI noise between sensitive and noisy wiring for up to 20dB reduction

in noise, or 90% NVR (equivalent to 6 inches of air spacing); innovative design installs

easily within Panduit wiring duct or when mounted separately, delivering greater design

flexibility to satisfy a wide range of applications

Bonding clip ^

Segmented design Speeds installation by allowing section(s) of the shield to be cut and snapped off at

intervals to easily size shield to length, with minimal deburring

Vertical wall slots Allow wires to cross the barrier at 90° when necessary, providing greater design flexibility

Horizontal cable tie slots Allow wire bundles to be held in place using cable ties to optimize cable management

and aesthetics

Zinc-plated steel and durable

black powder-coated surfaces

Durable powder-coated vertical surfaces for smooth edges; uncoated, corrosion

resistant, zinc-plated surface in shield contact area with sub-panel, ensures continuity

for proper bond to ground

When installing the shield inside a wiring duct, the bonding clip maintains electrical

continuity between the panel and shield for optimal noise mitigation and aesthetics

*Recommendations for distance separation between noisy and low-noise zones are referenced in IEEE 1100 Emerald Book, Recommended Practice for Powering and Grounding

Electronic Equipment. Consult the component manufacturer for specific wire segregation distance requirements.

**PanelMax™ Shielded Wiring Duct and Noise Shield deliver approximately 20dB of noise reduction across common industrial noise frequencies at 30mm wire separation

with an approximate 1 meter coupling length.

^The shielded wiring duct or noise shield, bonding clip (if used) and enclosure must be electrically bonded to ground for the shield to be effective (see Panduit installation

instructions EP001, for shielded wiring duct or RW260, for noise shield).

Shielded Wiring Duct and Noise Shield

Shielded Wiring Duct PanelMax™

Noise Shield

One of the core issues affecting the performance and reliability of

industrial control systems is electrical noise emitted from devices.

This electrical noise can create voltage spikes in victim wiring,

affecting component performance (as figure at left depicts).

Multi-Layered Noise Prevention and Mitigation

Panduit recommends following a multi-layered electrical noise prevention and mitigation strategy that also optimizes control

panel space utilization. This strategy includes grounding/bonding, segregation, shielding, and filtering practices to provide

optimal protection. This product bulletin focuses on noise mitigation via shielded wiring duct and noise shield products.

Refer to Panduit’s white paper WP-14, Optimizing Control Panel Layouts for Noise Mitigation in Factory Automation Systems,

for greater detail on other strategy recommendations.

Potential noise emitters/wiring

• Variable frequency and servo

motor drives

• Switching power supplies

• Contact switching of coils

and solenoid valves

Sensitive devices/wiring

• Communications/network

wiring (UTP Ethernet, RS232)

• High-speed counting signals

• Controllers

• Microprocessor based devices

Business Risks

• Productivity loss

• Downtime

• Maintenance/repair costs

• Device replacement costs

• Troubleshooting costs

Proper noise mitigation and panel layout practices help to ensure system productivity, quality, and safety. Panel designers

have historically used air spacing between components and wire pathways for noise mitigation, per IEEE recommendations.

With Panduit® PanelMax™ Shielded Wiring Duct and Noise Shield, panel designers can provide noise mitigation with reduced

air spacing requirements allowing for a space optimized control panel layout.

Considering Shielded Cables vs. Shielded Wiring Duct and Noise Shield

An alternative to shielded wiring duct or noise shield is to consider an increased use of shielded cables, such as

shielded twisted pair network cables and shielded control cables. Shielded cables provide superior noise mitigation

and noise voltage reduction, but at a typically higher premium and installed cost than unshielded cables. Panduit®

PanelMax™ Shielded Wiring Duct and Noise Shield add project value by providing sufficient noise mitigation at a lower

premium than a shielded cable solution.

Shielded Wiring Duct and Noise Shield advantages:

• Routing 10 standard unshielded cables in shielded wiring duct has up to a 35% lower purchased cost vs.

10 shielded cables routed in conventional wiring duct

• Shielded wiring duct and noise shield provide an effective noise mitigation solution when a shielded cable option

is not available or is difficult to source

Product Selection Guide

Noise and Its Effects on Industrial Controls

A conventional panel layout uses air spacing between pathways and components as a strategy to mitigate noise.

Duct color is used to indicate noisy (gray) and clean (white) pathways.

The strategy is to keep sensitive and potentially noisy wiring/cabling separated to mitigate noise:

Control and potentially sensitive wiring is routed in “clean” pathways (white color).

Power and potentially noise-emitting wiring is routed in “noisy” pathways (gray color).

A 6-inch distance is used between parallel noisy and clean wire pathways to mitigate noise coupling.^

Problems to resolve:

• Difficult to lay out and maintain segregated pathways throughout design

• Distance spacing often requires a larger panel size to implement, significantly increasing panel costs

and enclosure footprint requirements

• Distance separation between wire pathways can be compromised due to panel space constraints

^As a best wiring practice, where necessary, sensitive and potentially noisy wires should cross only at 90° in order to minimize the coupled length between wires.

Conventional Panel Layout

An optimized panel layout uses PanelMax™ Shielded Wiring Duct and Noise Shield to provide noise mitigation with reduced

distance spacing required between clean and noisy pathways. PanelMax™ DIN Rail Wiring Duct is also implemented to

provide additional panel space savings.

The strategy is to shield, mitigating noise between sensitive and potentially noisy wiring/cabling while reducing panel space:

Control and potentially sensitive wiring is routed in “clean” pathways (white color).

Power and potentially noisy wiring is routed in “noisy” pathways or shielded wiring duct (gray color).

Conventional wiring duct contains motor cabling. Noise shield is mounted separately to shield control and

network cabling.

Optionally, noise shield is mounted inside shielded wiring duct to segregate and shield sensitive cabling from noise.

Shielded wiring duct mitigates potential noise emission from cabling inside the duct near clean pathways.

Shielded wiring duct mitigates potential noise emission from motor drives onto the PAC device and sensitive

wiring connections.

PanelMax™ DIN Rail Wiring Duct is added to the design to provide additional space savings.t

Layout Benefits:

• Robust noise mitigation is achieved

• Shielded wiring duct and noise shield reduce panel height by over 20% and DIN Rail wiring duct reduces panel width

by over 20% resulting in significant enclosure footprint reduction

• Net value of space saved in panel/enclosure with cost of PanelMax™ Shielded Wiring Duct and Noise Shield and

DIN Rail Wiring Duct is between $1,500 and $5,000n
