Explains precautions and safety standards when using UPS (Uninterruptible Power Supplies) overseas!

Demand for UPS (uninterruptible power supplies) is increasing worldwide.
The background to this trend is the development of the IT and communications industries, as well as the development of cloud services and remote environments. In Southeast Asia and India, where many Japanese companies have production bases, there are many areas with unstable power sources, such as frequent blackouts, and UPS has become an important infrastructure supporting production activities.

In this article, we will explain the precautions to take when using a UPS overseas and the international standards that apply overseas.

1. Precautions when using a UPS (Uninterruptible Power Supply) overseas

If I want to use UPS overseas, what should I pay attention to when selecting and transporting?

1. Voltage/Frequency/Load

Voltage and frequency differ between Japan and other countries. Voltage is divided into 100V and 200V systems, with 100V being the mainstream in Japan. Frequency also differs by country, with 50Hz in eastern Japan and 60Hz in western Japan.
When selecting a UPS, you need to check the voltage and frequency of the country in which you will be using it and select a compatible UPS. If you select the wrong one, the load of the UPS may damage your equipment, so you need to be careful.

2. Shape of outlet and plug

The shapes of electrical outlets and plugs may differ between Japan and other countries. In such cases, you may need to use an appropriate conversion adapter or take other appropriate measures.

3. Operating environment

You should also check whether the UPS is suitable for the environment in the country you plan to use it in. UPSs have set "ambient temperature" and "relative humidity" limits for use. If you plan to use a UPS in an area with a different environment than Japan, such as a hot and humid region, you will need to check.

4.Transportation Method

If the batteries used in the UPS are subject to transportation regulations, air and sea transport may be restricted. Since policies may differ depending on the airline, be sure to check in advance.

The lead-acid batteries used in SANYO DENKI CO., LTD. 's UPS are non-spillable, so they can be treated as non-hazardous goods and transported by air, sea, and land. Lithium-ion batteries have different transport rules, so please contact us separately.

5. After-sales service

If you use a UPS purchased in Japan overseas, there may be no local service center and you may not be able to receive after-sales service, which can cause problems later on. Therefore, choosing a UPS manufacturer that offers overseas service is also an important factor.

2. Certification marks (safety standards) of each country

Whether a UPS can be used safely overseas can be determined by whether it is certified to overseas safety standards.
Overseas safety standard certification is a certification that indicates that a product meets certain international safety standards and that the product is confirmed to be safe for use. This means that the product meets specific safety requirements and has been designed, manufactured, and tested in accordance with general safety standards. Overseas safety standard certification is very important for products sold in international markets.

Now, we will introduce the "certification marks" of each country that are used to determine whether a product is certified by overseas safety standards.

*If the UPS is pre-installed in the device or imported together with the device as ancillary equipment, it may be possible to import it locally without the need for a standard. However, when importing a UPS alone, in principle, the UPS is checked for its safety standards in each country. This applies when the UPS is shipped separately due to a breakdown replacement or additional demand.

1.UL Standard (USA)

The "UL Standard" is a product safety standard established by Underwriters Laboratories Inc. (UL).
Its purpose is to standardize the functionality and safety of everything from materials, equipment, parts, and tools to products. Although UL certification is optional, many state projects require UL certification, and many electrical products in the United States are UL certified.
*Quoted from JETRO Trade and Investment Consultation Q&A "Overview of UL Standards: United States"

2.CE marking (EU)

"CE marking" is a mark that indicates that specified products sold (marketed) in the EU comply with EU standards.
Most of the essential requirements are related to product safety, but in recent years, it has become necessary to declare the conformity of products to the environmental performance standards set out in the RoHS (Restriction of Hazardous Substances) Directive and the Ecodesign Directive through CE marking. The manufacturer (importer) of the product in question, or a third-party certification body acting on its behalf, performs the required conformity assessment and affixes the marking to the product, packaging, and attached documentation. Products with the correct CE marking are guaranteed to be freely sold and distributed within the EU.
*Quoted from JETRO Trade and Investment Consultation Q&A "Overview of CE Marking: EU"

3. National Standards

There are certification marks (safety standards) in other countries as well. Here are some of them.

"BIS" is the Bureau of Indian Standards, which is a standard that must be obtained for products to be exported or sold in India. In recent years, the number of items to which compulsory certification is applied has been expanding, and in principle, UPS devices up to single-phase 10kVA cannot be sold in India unless they have obtained this standard.

"TIS" stands for Thailand Industrial Standards, a national standard established to promote standardization in the industrial field. It is called TIS or TIS standard. It applies to all industrial products.
*Quoted from JETRO: Overview of Thai Industrial Standards (TIS) and obtaining the certification mark

「BSMI認証」は，台湾国内で製造および輸入される対象製品に対し,BSMI(台湾経済部の管轄下にある標準検験局)が商品検験法に基づき，検査および認証・認可を行う仕組みです。商品検験法の第六条では，検査基準を満たさない対象製品の陳列や販売をしてはならないと定めています。対象製品の分野は多岐にわたります。
