Information Technology Equipment - Safety - Part 1: General RequirementsUL 60950-11.1 Scope1.1.1 Equipment covered by this standardThis standard is applicable to mains-powered or battery-powered information technology equipment, including electrical business equipment and associated equipment, with a RATED VOLTAGE not exceeding 600 V and designed to be installed in accordance with the Canadian Electrical Code, Part I, CSA C22.1; CSA C22.2 No. 0; the National Electrical Code, NFPA 70; and the National Electrical Safety Code, IEEE C2.The standard is also applicable to equipment, unless otherwise identified by a marking or instructions, designed to be installed in accordance with Article 645 of the National Electrical Code, NFPA 70, and the Standard for the Protection of Electronic Computer Data-Processing Equipment, NFPA 75.See annex nae for examples of and references to regulatory requirements that may apply to this equipment.This standard is also applicable to such information technology equipment:- designed for use as telecommunication terminal equipment and TELECOMMUNICATION NETWORK infrastructure equipment, regardless of the source of power;- designed and intended to be connected directly to, or used as infrastructure equipment in, a CABLE DISTRIBUTION SYSTEM, regardless of the source of power;- designed to use the AC MAINS SUPPLY as a communication transmission medium (see note 4 of clause 6 and note 3 of clause 7).This standard specifies requirements intended to reduce risks of fire, electric shock or injury for the OPERATOR and layman who may come into contact with the equipment and, where specifically stated, for a SERVICE PERSON.This standard is intended to reduce such risks with respect to installed equipment, whether it consists of a system of interconnected units or independent units, subject to installing, operating and maintaining the equipment in the manner prescribed by the manufacturer.NOTE The requirements of IEC 60065 may also be used to meet safety requirements for multimedia equipment. See IEC Guide 112, Guide on the safety of multimedia equipment. A list of informative references is given in annex q: "Bibliography".This list is not intended to be comprehensive, and equipment that is not listed is not necessarily excluded from the scope.Equipment complying with the relevant requirements in this standard is considered suitable for use with process control equipment, automatic test equipment and similar systems requiring information processing facilities. However, this standard does not include requirements for performance or functional characteristics of equipment.1.1.2 Additional requirements Requirements additional to those specified in this standard may be necessary for:- equipment intended for operation in special environments (for example, extremes of temperature; excessive dust, moisture or vibration; flammable gases; and corrosive or explosive atmospheres);- electromedical applications with physical connections to the patient;- equipment intended to be used in vehicles, on board ships or aircraft, in tropical countries, or at altitudes greater than 2 000 m;- equipment intended for use where ingress of water is possible; for guidance on such requirements and on relevant testing, see annex t.NOTE Attention is drawn to the fact that authorities of some countries impose additional requirements.1.1.3 ExclusionsThis standard does not apply to:- support equipment, such as air conditioning, fire detection or fire extinguishing systems;- power supply systems which are not an integral part of the equipment, such as motor-generator sets, battery backup systems and transformers;- building installation wiring;- devices requiring no electric power.
