Answers for industry.
Exporting Successfully to the USA with a Sound Knowledge of Applicable Standards Product liability laws in the USA are significantly stricter than in Europe. Products to be exported to North America are required to be certified by the Underwriters Laboratory (UL), particularly when it comes to industrial control equipment. This brochure aims to explain the meaning of UL certification and to describe the corresponding aspects to be considered. As well as information on how you can leverage Siemens’ comprehensive know-how on this topic to your advantage and broad portfolio of UL-certified low-voltage controls and distribution products.
Benefiting all along the line – with the UL know-how by Siemens • You can depend on our strong and reliable product and system portfolio, which have been designed with consideration to the UL standards right from the development phase. • Save commissioning time with expert UL consulting services and training courses. • Obtain assistance from our UL-certified manufacturer in Chemnitz in relation to configuration, production and delivery of complete control panels. You can rely on cost-effectiveness during production and operation of control panels for North America. • Stay flexible for a highly diverse range of solutions and add-ons with our comprehensive and matched product portfolio: from the supply of the industrial control panel to the machine‘s smallest actuator. UL and IEC differ fundamentally. The IEC standards merely specify the minimum safety requirements of a device or system. Technical details of the safety requirements’ constructional implementation are up to the manufacturers. In contrast, the standards for the American market are far more detailed. Depending on the standard, the required process may be monitored from product design to product production down to application, mounting and operation.

Operating permission from AHJ2) Commissioning prerequisite for end customer ¹⁾ Nationally Recognized Testing Laboratories ²⁾ Authority Having Jurisdiction
Every electrical machine or system in the USA is investigated by an inspector, the so-called Authority Having Jurisdiction (AHJ) prior to commissioning. The National Electrical Code (NEC), also known as NFPA 70 respective application-specific standards such as NFPA 79 as well as local standards and specifications form the basis for acceptance. Acceptance is required by law in the USA. Operators failing to have their machines or systems inspected by an AHJ risk both loss of insurance as well as power supply. For successful field acceptance, a correct configuration according to the applicable standards is of the essence. The illustration above shows four possible acceptance methods. 4
Conclusion For manufacturing UL-compliant industrial control panels, the employment of UL-certified products alone is not sufficient. The interaction of devices in accordance with the respective application standards as well as the acceptance of the industrial control panel in its actual application environment are critical.
Overview of the Most Important US Standards There is a whole series of organizations in the USA that are dedicated to promoting technical safety. Which standards and directives are relevant in the individual case can only be safely determined in conjunction with the respective application.
The following directives/standards are of essential importance to mechanical engineers and panel builders: • UL508A for industrial control panels • NFPA 79 (Electrical Standard for Industrial Machinery) for industrial machines and • NEC (National Electrical Code, NFPA 70) for electrical on-site installation. Local conditions also have to be considered. These are specified by the Occupational Safety and Health Administration (OSHA), one of the most important organizations for the enforcement of safety requirements. It ensures safe and healthy occupational conditions and the protection of persons at their workplace by law, which became effective in 1970. In this context, OSHA also publishes various standards on safety technology pertaining to machines and systems, which are to be considered for the respective application case.
Here are two examples: When it comes to the equipment of a liquid filling system, the FDA (Food and Drug Administration) has to be consulted when it is for foodstuff. Additionally, the conditions for hazardous locations may be observed if there is alcohol processed (danger of inflammable liquids or explosive gases).
Who or what is NFPA? NFPA (National Fire Protection Association) is an organization in the USA that publishes a comprehensive set of regulations for fire protection, electrical safety and construction safety. It was founded in 1896 and has published over 300 standards to date. NFPA does not certify products. It limits itself exclusively to drawing up standards, such as the NEC and NFPA 79 standards relevant to control panel production. NEC is considered state-of-the-art by the US legal system. You will find further information at www.NFPA.org
Who or what is UL? Underwriters Laboratories Inc.® (UL) is one of the world’s leading organizations for testing and certification in the field of product safety. This independent, non-profit US organization was founded in 1894 at the request of American fire insurance companies to analyze the fire hazards posed by electrically operated devices. Today, UL tests and certifies a wide range of materials, components and end products for their operational safety, particularly with regard to potential personal injury and fire formation. The organization maintains subsidiaries in numerous European countries. Detailed information on the US organization as well as contact details for the various European subsidiaries are available on UL’s website at www.ul.com

Seeing Clearly through the Jungle of Standards In the USA, the National Electrical Code (NEC), which also deals with the topics of “Industrial Control Panels (Article 409)” and “Industrial Machinery (Article 670)”, must generally be complied with when it comes to setting up electrical equipment. In these sections, reference is also made to the UL 508A for Industrial Control Panels and the NFPA 79 for Industrial Machinery standards, among others.
In the case of industrial machinery and plant, a distinction is generally made between factory wiring (sometimes also called internal wiring) and field wiring. Factory wiring is understood to be wiring that is laid and connected only in the control panel (i.e. under supervision), while field wiring is wiring that is connected by an electrician “in the field”. Application range of UL 508A UL 508A, the relevant standard for the control panel (factory wiring), covers control panels with a voltage up to 600 V for normal ambient conditions. It applies between the electrical infeed and the outgoing feeder terminals to the field. On the topic of field wiring, only the interfaces (e.g. outgoing feeder terminals) to the field are dealt with. According to NEC Article 409, an industrial control panel is understood to be an arrangement of two or more components in the main circuit, the control circuit or hybrid circuits. Application range of NFPA 79 NFPA 79 is the relevant standard for electronic components of industrial machinery up to 600 V for normal ambient conditions. It applies from the electrical infeed to the individual machine assemblies. This standard is aimed at protecting persons and plants.
Which standard applies? Before configuration, it is necessary to clarify which standard is applied in which application cases. When to use UL 508A? When to use NFPA 79? When to use both? The requirements and interfaces of both standards are clearly set out with regard to most points. If requirements overlap, however, the standard with the higher requirements in relation to the respective point must be applied.
An example to improve understanding: UL 508A does not clearly define the maximum filling of cable ducts. Thus, it could be assumed that filling is 100%. In NFPA 79, though, it is limited to a maximum of 50%. This is why NFPA 79 must be applied in this case. Both standards are highly important for the manufacturer of industrial machinery.

Relevant Contents of UL 508A Overcurrent protection according to system type UL 508A distinguishes between straight rating and slash rating. Which of these two ratings applies depends on the existing system type. Slash rating There are two voltages (phase – phase / phase – ground) in a solidly grounded wye network. These two voltages are also specified along with the rating, e.g. 480 Y/277 V. The rating for such a network is called the slash rating.
Straight rating In the common industrial networks (see table) there is only one voltage. Such networks are called “straight networks.” When choosing short-circuit protection devices, attention must be paid to whether devices are approved for straight or slash rating.
Industrial networks in the USA (industry and commercial) Slash rating
Straight rating
3 phases, 4 wires Solidly grounded wye, 3-phase, 4-wire
3 phases, 3 wires Corner grounded delta, 3-phase, 3-wire
3 phases, 3 wires Ungrounded wye, 3-phase, 3-wire
Note: the PE must not carry any current. There is no PEN conductor -> N = grounded conductor (white or gray); separate conductors must be used for PE and N.

¹⁾ Y describes the solidly grounded circuit. The value “Y” indicates the voltage between the phases (e.g. 480 V), and the value behind the slash indicates the voltage between the phase and the grounding or the neutral conductor (e.g. 277 V with 480 V voltage between the phases).
Overcurrent protection The term “overcurrent” refers to the overload, short circuit and ground-fault current. Overcurrent protection is understood to be a device designed to open a circuit when the rated current is exceeded. The ampere rating of the device is selected for a circuit to terminate a condition where the current exceeds the rating of conductors and equipment due to overloads, short circuits and faults to ground.

Branch circuit protection: Overcurrent protection with an ampere rating selected to protect the branch circuit (devices and cables). For a motor branch circuit, the overcurrent protection is required for overcurrents due to short circuits and faults to ground only. 2) Power circuit internal wiring/factory wiring: The devices may only be connected by the factory, e.g. if soldered or crimped connections are required. 3) Field wiring: Field wiring is mostly done by an electrician without specially prepared conductors. 1)

Power circuit according to UL 508A Short-circuit current rating of the control panel power circuit An industrial control panel must be marked with a socalled Short-Circuit Current Rating (SCCR). With IEC, this approximately corresponds to the lcw value of the switchboard. The NEC 2011 Article 409 describes the specifications of short-circuit current rating marks on industrial control panels (with reference to UL 508A, SB4). For shortcircuit rating, not only the short-circuit breaking capacity, e.g. of the circuit breaker, but also the short-circuit rating of every individual device in the power circuit is relevant.
Distinction between branch and feeder circuits in the power circuit The distinction between branch and feeder circuits applies only to the power circuit. The control circuit is not a branch circuit and it does not belong to the feeder circuit either. Other rules apply here, which are considered in the section on control circuits. • Feeder circuit The conductors and circuitry on the supply side of the branch circuit overcurrent protective device.
• Branch circuit The conductors and components following the last branch circuit overcurrent protective device protecting The SCCR-relevant components in the power circuit include the load. circuit breakers, contactors, overload relays, solid-state switching devices, terminals, busbars, the line side of con- Protecting other loads trol transformers and frequency converters, however, no Non-motor loads must be protected as specified in the internal wiring of the industrial control panel. The lowest manufacturer’s UL report. One essential difference with value is applicable to the entire industrial control panel. respect to the IEC world is that circuit breakers according A transformer with a higher short-circuit current must not to UL 489 or fuses according to UL 248-4...12 must be be connected to the industrial control panel. used in both cases. Infeed The specifications for the infeed to the industrial control panel also differ from the IEC standards. For example, only certain devices are permitted as main switches, e.g. circuit breakers according to UL 489.
Combination Motor Controller Examples Assembly options of motor branch circuits The assembly options of combination motor controllers within IEC greatly differ from those for the UL market. Combination motor controllers according to IEC may cause UL inspectors or the AHJ to impose the so-called “red flag,” which means that the machine can only be put into operation after a significant change.

Control circuit A circuit that carries the electric signals directing the performance of a controller, and which does not carry the main power circuit. Control circuits are, in most cases, limited to 15 A. There are various ways of realizing control circuits: • Direct tap-off upstream of the branch circuit protective device. Here, respective protective devices are to be used, e.g. circuit breakers according to UL 489. • Direct tap-off downstream of the branch circuit protective device. Here, also so-called supplementary protectors can be used, e.g. miniature circuit breakers according to UL 1077. • Via control transformers or DC power supply units. Caution: Various protective devices may not be approved for this application. Low-voltage limited energy circuit A circuit with 30 Vrms (root mean square value) or 42.4 Vpeak or 42.4 Vpeak or DC voltage. Power is limited to 100 VA, and current to 5 A. An example of such a control circuit would be 24 V, fused with 4 A.

Class 2 control circuit A control circuit supplied from a source having limited voltage (30 Vrms or less) and current capacity, such as from the secondary of a Class 2 transformer and rated for use with Class 2 remote-control or signaling circuits. Class 1 common control circuit (acc. to UL 508A) A control circuit on the load side of an overcurrent protective device where the voltage does not exceed 600 volts, and where the power available is not limited, or a control circuit on the load side of a power limiting supply, such as a transformer. Enclosure types according to UL In the USA, the enclosure type refers to the degree of protection (comparable to the IP degree of protection in Europe). The UL system works differently to the IEC system, e.g. a higher digit is not equivalent to higher protection, but different protection. There are also rules for mounting components onto the enclosure or through the enclosure plate. UL mark According to UL 508A, the control panel must be marked in detail. From the rating plate to the wire end identification, extensive rules must be complied with.

The UL Marks in Detail For the marking of UL-certified products, a general differentiation is made between listed devices and recognized components. Further variants exist for the Canadian market.
UL Listing Mark: This is one of the most common UL marks. If a product carries this mark, it means UL found that representative samples of this product met UL’s safety requirements. These requirements are primarily based on UL’s own published standards for safety. This type of mark is seen commonly on appliances and computer equipment, furnaces and heaters, fuses, electrical panelboards, smoke and carbon monoxide detectors, fire extinguishers and sprinkler systems, personal flotation devices like life jackets and life preservers, bullet-resistant glass, and thousands of other products. Our own portfolio, for example, offers contactors in accordance with UL 508 or circuit breakers in accordance with UL 489. C-UL Listing Mark: This mark is applied to products for the Canadian market. The products with this type of mark have been evaluated to Canadian safety requirements, which may be somewhat different from U.S. safety requirements. You will see this type of mark on appliances and computer equipment, vending machines, household burglar alarm systems, lighting fixtures, and many other types of products. C-UL Listing Mark: UL introduced this new Listing Mark in early 1998. It indicates compliance with both Canadian and U.S. requirements. The Canada / U.S. UL mark is optional. UL encourages those manufacturers with products certified for both countries to use this new, combined mark, but they may continue using separate UL marks for the United States and Canada. Recognized Component Mark: This mark consumers rarely see because it is specifically used on component parts that are part of a larger product or system. These components may have restrictions on their performance or may be incomplete in construction. The Component Recognition mark is found on a wide range of products, including some switches, power supplies, printed wiring boards, some kinds of industrial control equipment and thousands of other products. They shall only be installed by experts of the manufacturer according to the so-called “Conditions of Acceptability (CoA)” that apply to these devices. Amongst others, our portfolio contains the following products with the UR mark: miniature circuit breakers according to UL 1077, time switches according to UL 917, and SITOR fuses. Canadian Recognized Component Mark (similar to Recognized Component Mark – see above): Products intended for Canada carry the Recognized Component Mark “C.”
Recognized Component Mark for Canada and the United States: This new UL Recognized Component Mark, which became effective in 1998, may be used on components certified by UL to both Canadian and U.S. requirements. Although UL had not originally planned to introduce a combined Recognized Component Mark, the popularity of the Canada/U.S. Listing and Classification Marks among clients with UL certifications for both Canada and the United States has led to the new Mark.
and are issued by the so-called NRTLs (Nationally Recognized Testing Certifications such as Laboratories) after successful testing. The OSHA (Occupational Safety and Health Administration) has accredited Underwriters Laboratories Inc. as an NRTL.

Relevant Contents of NFPA 79 NFPA 79 deals with electrical safety for an entire machine, both inside and outside the control panel. Above all, the following contents and stipulations of NFPA 79 must be observed in relation to machine and control panel production.
Cables outside the control panel (field wiring) NFPA 79 stipulates which cables are permitted from the control panel to the load, how they are to be designed and how they have to be laid. Motors in the field NFPA 79 describes the dimensions and selection criteria for electrical motors. Identifications, safety information and technical documentation The standard stipulates in detail which identifications, safety information and technical documentation are required to be available. Machine safety NFPA 79 deals with the subject of machine safety only in part. The standard essentially refers to other standards, e.g. to IEC and ANSI standards when it comes to the risk analysis.
Tests and verifications According to NFPA 79, diverse tests and verifications have to be carried out in contrast to UL 508A, for example checking the continuity of PE conductors, voltage testing, and much more. Stipulations for control equipment NFPA 79 contains detailed specifications for control equipment (such as push buttons, Emergency Stop) as well as its installation location, mounting and distances in the operating range. Other NFPA 79 topics • It includes specifications for Emergency Stop and emergency shutdown (e.g. stop categories). • Control panel topics such as infeed and the main switch, system protection, protection against electrical hazards, motor protection, accessories and lighting.

UL 508
No matter which load you want to switch, you’ll find the right solution among the SIRIUS contactors. With high contact reliability and a compact, modular design, and also particular robustness and longevity, as part of the SIRIUS modular system they are the ideal partner for operational switching.
SIRIUS function modules for mounting on 3RT2 contactors
3RA28
UL 508
To reduce control circuit wiring when assembling directon-line, reversing and wye-delta starters, function modules are available that can simply be plugged onto the newgeneration 3RT2 contactors in sizes S00 and S0. Thus, this size of contactor assemblies can be realized fast, easily and above all fault-free. The function modules with starter functions are also available with interfaces for AS-Interface or for IO-Link. Thus, in addition to saving on wiring within the feeders, interfacing to higher-level control systems can also be substantially simplified.

Test Privileges of the Production Facility Amberg
In 1995, the production facility Amberg was granted the authorization of implementing certifications in accordance with the Client Test Data Program (CTDP). As a CTDP customer of UL, the production facility is entitled to carry out tests and independently prepare test as well as UL reports that contain the product description. UL merely verifies the compliance of the test and UL reports with UL standards. This way, the production facility Amberg has acquired a way higher degree of autonomy for the testing and certification process.
To ensure the products’ compliance with the UL standards, UL inspectors regularly audit our factory within the so-called follow-up service. Follow-up service means that one or several devices are compared with the UL-certified documents, which are described in detail in a report. UL inspectors regularly visit the production plants to verify that the product is produced as described (example: SIRIUS contactors). With some devices, repeat tests are additionally implemented at regular intervals.
