[June 8, 2018] OMRON Corporation today announced the following notice regarding some of its Uninterruptible Power Supply units.

In some UPS products stocked by OMRON Corporation, parts have been discovered that contain materials which do not comply with internal product environmental standards (see affected products below), adopted on a voluntary basis by OMRON. The discovery was made by OMRON while conducting inspections based on such standards. In response, OMRON immediately halted shipment of the affected products. Models confirmed to be in compliance with such internal standards during the inspection are continuing to be shipped.

Customers who wish to exchange affected products currently in use may exchange them free of charge. See below for details.

OMRON sincerely apologizes to its customers, business partners, and other persons involved for the inconvenience and concern caused by our failure to abide by the high Omron standards to which we are committed.

*UPS stands for uninterruptible power supply, an electronic device that continues to supply power in the event that the normal power supply is cut off, as in a blackout. The affected products are designed for use with small appliances such as PCs and workstations.

ii. Total Sales of Models Potentially Affected: 554,227 units

iii. Number of Units of Affected Products: Of the models in question listed above, an investigation is currently in progress to determine the number of units not in compliance with OMRON's product environmental standards.

2.Background

On a voluntary basis, Omron has implemented internal, global product environmental standards which reference the EU's Restriction of Hazardous Substances (RoHS) standard. Under RoHS, the use of six specific materials (lead, mercury, cadmium, hexavalent chromium, PBB (polybrominated biphenyl), and PBDE (polybrominated diphenyl ether)) is restricted in electronic and electrical devices. To date, OMRON has received certificates from its suppliers that certify the non-inclusion of these specific substances above regulated amounts. However, during a recent internal inspection, PBDE (polybrominated diphenyl ether), one of the restricted substances, was detected at amounts exceeding such OMRON internal standards in some product casings of the models in question.

OMRON immediately halted shipment of products using potentially affected parts, and in addition to notifying resellers, it conducted confirmations of product compliance with our product environmental standards. Shipment of models that were confirmed to be in compliance were resumed. The regulated chemical substance in question had been mistakenly added by the third party supplier as a flame retardant to molded parts used in the product casing. There have been no known reports of harm or injury to individuals resulting from such use of the chemical in the UPS devices.

3.Customer Support

For customers who wish to exchange an affected product currently in use, OMRON will exchange it free of charge. Detailed information will be provided.

4.Product Environmental Compliance Efforts

OMRON has undertaken important voluntary efforts to incorporate the best global rules into its environmental product standards. Going forward, we will be even more diligent in monitoring suppliers and will conduct voluntary inspections of parts used in our products. We will continue to take all appropriate steps to ensure our products comply with these best available global standards.
