Frequently Asked Questions


UL is a voluntary standard that is certified by the nonprofit testing organization of Underwriters Laboratories Inc. founded in 1894. However, it became the de-facto standard in the United States, and this organization conducts the certification test of an electric appliance.

UL 1778 applies to Uninterruptible Power System (UPS). The primary function of the UPS for this Standard is to ensure continuity of an alternating power source. The Uninterruptible Power System also serve to improve the quality of the power source by keeping it within specified characteristics. This Standard applies to movable, stationary, fixed, and built-in UPS for distribution systems up to 600 V a.c. This Standard is intended to reduce the risk of fire, electric shock, or injury to persons from installed equipment, both as a single unit or as a system of interconnected units, subject to installing, operating, and maintaining the equipment in the manner prescribed by the manufacturer.

Our SANUPS Uninterruptible Power Supply systems for North America market are all UL1778 certified.

The International Electrotechnical Commission (IEC) is the world’s leading organization that prepares and publishes International Standards for all electrical, electronic and related technologies.

IEC 62040-1 applies to movable, stationary, fixed or built-in UPS for use in low-voltage distribution systems and that are intended to be installed in an area accessible by an ordinary person or in a restricted access area as applicable, that deliver fixed frequency AC output voltage with port voltages not exceeding 1000 VAC or 1500 VDC and that include an energy storage device. It applies to pluggable and to permanently connected UPS, whether consisting of a system of interconnected units or of an independent group, subject to installing, operating and maintaining the UPS in the manner prescribed by the manufacturer.

IEC 62040-2 is a type test product standard for electromagnetic compatibility (EMC) and applies to movable, stationary, fixed or built-in, pluggable and permanently connected UPS for use in low-voltage distribution systems with an environment being either residential, commercial, light industrial or industrial, which deliver output voltage with port voltages not exceeding 1500 VDC or 1000 VAC and which include an energy storage device.

CE marking is a conformity certification with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA). The CE marking is recognized worldwide and is the manufacturer’s declaration that the product meets the requirements of the applicable EC directives.

Electromagnetic compatibility (EMC) is the concept of enabling different electronics devices to operate without mutual interference – Electromagnetic Interference, EMI – when they are running close to each other.

EMC is now an integral part of any electronics design project. With standards now implemented and enforced across the world, Sanyo Denki’s UPS products have been tested to ensure it meets the relevant EMC standards. While this presents an additional challenge to the electronics design engineer, it is essential that good EMC practices are employed and the EMC performance of the product is sufficient to ensure it operates correctly under all reasonable scenarios.

The Federal Communications Commission (FCC) regulates interstate and international communications by radio, television, wire, satellite, and cable in all 50 states, the District of Columbia and U.S. territories. An independent U.S. government agency overseen by Congress, the commission is the United States’ primary authority for communications law, regulation, and technological innovation.

Nearly every electronics device sold inside the United States radiates unintentional emissions and must be reviewed to comply with the Code of Federal Regulations (CFR) Part 15 before it can be advertised or sold in the US market. CFR Part 15’s Subpart B deals with unintentional radiators such as computers that were not intended to produce radio waves. All Sanyo Denki’ SANUPS UPS systems comply with CFR15 Part 15 Sub-B Class-A.  

Voluntary Control Council for Interference by Information Technology Equipment – VCCI – is a membership organization with the purpose to suppress electromagnetic interference from ITE in Japan. VCCI started as a voluntary organization in 1985. VCCI was reconstituted as a legal entity “VCCI Council” in April 2009. The number of VCCI members is approximately 1,200 which is half Japanese companies and a half overseas companies. VCCI and FCC agreed to mutually accept test reports issued by accredited laboratories of the other country in February 2007 in the framework of Japan-US telecommunication MRA.

RoHS stands for Restriction of Hazardous Substances and impacts the entire electronics industry and many electrical products as well. The original RoHS, also known as Directive 2002/95/EC, originated in the European Union in 2002 and restricted the use of six hazardous materials found in electrical and electronic products. All applicable products in the EU market since July 1, 2006, must pass RoHS compliance. Directive 2011/65/EU was published in 2011 by the EU, which is known as RoHS-Recast or RoHS 2. RoHS 2 includes a CE-marking directive, with RoHS compliance now being required for CE marking of products.

JIS – Japanese Industrial Standards specifies the standards used for industrial activities in Japan. The Japanese Industrial Standards Committee coordinates the standardization process and publishes through the Japanese Standards Association. The objective of the Japanese Standards Association is “to educate the public regarding the standardization and unification of industrial standards, and thereby to contribute to the improvement of technology and the enhancement of production efficiency.”
