Momentus 4200.2 Product Manual, Rev. D

2.13 Reliability

2.14 Agency certification

2.14.1 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.

2.14.2 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.

Seagate uses an independent laboratory to confirm compliance with the EC directives specified in the previous

paragraph. Drives are tested in representative end-user systems. Although CE-marked Seagate drives comply

with the directives when used in the test systems, we cannot guarantee that all systems will comply with the

directives. The drive is designed for operation inside a properly designed enclosure, with properly shielded I/O

cable (if necessary) and terminators on all unused I/O ports. Computer manufacturers and system integrators

should confirm EMC compliance and provide CE marking for their products.
