Agency certification

2.13.1

Safety certification

The drives are recognized in accordance with UL 1950 and CSA C22.2 (950) and meet all applicable sections
of IEC950 and EN 60950 as tested by TUV North America.
2.13.2

Electromagnetic compatibility

Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Elec-
tromagnetic Compatibility Directive (89/336/EEC). Testing is performed to the levels specified by the product
standards for Information Technology Equipment (ITE). Emission levels are defined by EN 55022, Class B and
the immunity levels are defined by EN 55024.
