1DV.1 DR Modify this clause by adding the following text:
1DV.1.1 This standard is applicable to equipment designed to be installed in accordance with the Canadian Electrical Code (CE Code), Part I, CSA C22.1-18; the National Electrical Code, NFPA 70-2017; and the National Electrical Safety Code, IEEE C2 2017.
1DV.1.2 The standard is applicable to equipment, when identified by a marking or instruction [see Annex DVK (Annex DVA, Clause 1 entry)], designed to be installed in accordance with Article 645 of the National Electrical Code, NFPA 70-2017, and the Standard for the Protection of Information Technology Equipment, NFPA 75-2017.
1DV.1.3 See Annex DVA for requirements and references to regulatory requirements that apply to this equipment, as applicable.
1DV.2 D2 Modify Clause 1 by adding the following text:
1DV.2.1 This standard includes additional requirements for equipment used for entertainment purposes intended for installation in general patient care areas of health care facilities. See Annex DVB.
1DV.2.2 This standard includes additional requirements for equipment intended for mounting under cabinets. See Annex DVC.
1DV.2.3 Additional requirements for equipment with DC power transfer through communication cables and ports are given in IEC 62368-3. IEC 62368-3 clause 5 for DC power transfer at ES1 or ES2 voltage levels is considered informative. IEC 62368-3 clause 6 for remote power feeding telecommunication (RFT) circuits is considered normative (see ITU K.50). Alternatively, equipment with RFT circuits are given in either UL 2391 or CSA/UL 60950-21. RFT-C circuits are not permitted unless the RFT-C circuit complies with RFT-V limits (≤ 200V per conductor to earth).
1DV.2.4 This standard does not cover Modular Data Centers (MDCs), only the information and communication technology equipment contained within.
NOTE In the U.S., Modular Data Centers are covered by UL 2755, Modular Data Centers.
1DV.3 DR Modify Clause 1 by replacing Note 3 with the following:
NOTE 3 For information on this subject, see IEC 62305-1, NFPA 780 or CAN/CSA-B72.
1DV.4 DC Modify Clause 1 by adding the following paragraph and Note:
Battery backup systems including storage batteries and battery management equipment that are not an integral part of stationary AV and ICT equipment, such as provided in separate cabinets, are subject to the appropriate standard for battery backup systems, such as UL 1973, Batteries for Use in Stationary, Vehicle Auxiliary Power and Light Electric Rail (LER) Applications.
NOTE 9DV See Figures 1.1 and 1.2 of UL 1973 for more information on independent electric energy storage systems (EESS) covered by UL 1973, which can consist of both low voltage (class ES or ES2) and high voltage (class ES3) subsystems, battery management, thermal management, and related features and safeguards. When interconnected with AV, IT, and CT Equipment, and typically used in conjunction with an uninterruptible power supply (UPS), such EESS typically serve as a short-term substitution of the mains supply during power outages and similar disturbances.
1DV.5 DC Add Clause 1DV.5.1 to Clause 1
1DV.5.1 Power Distribution Equipment and Subassemblies
1DV.5.1.1 This standard also is applicable to power distribution subassemblies connected to a mains used to distribute power entirely within a system of equipment also covered by this standard, such as power distribution units (PDUs) in the form of cord-connected power strips and shelves with multiple power outlets (receptacles) and intended to be installed in system racks, cabinets, home entertainment centers, etc.
1DV.5.1.2 For equipment covered by this standard that incorporates components and subassemblies that perform a power distribution and control function covered by other standards, such as panelboards, load transfer equipment, or uninterruptible power systems utilized in power conditioners and computer power centers, this standard only may be used for investigation of safety for those aspects not covered by the other standards.
1DV.5.1.3 This standard also does not apply to stand-alone equipment used for distribution of mains power that is covered by individual power distribution equipment standards.
1DV.5.1.4 Based on the specific function, the following requirements are applicable to the stand-alone distribution equipment, or apply additionally to power distribution subassemblies and components of equipment covered by this standard, as described in Clauses 1DV.5.1.1 to 1DV.5.1.3:

NOTE 1 It is assumed that power distribution equipment covered by the scope of this standard is interconnected to the outlet of a branch circuit as defined in Section 0 of the CE Code, Part I, and Article 100 of the NEC. In the case of cord-connected equipment, the outlet is the receptacle associated with the building wiring. In the case of permanently connected equipment, the outlet is the interface between the branch circuit conductors associated with the building wiring and the input terminals, pressure connectors, or leads associated with the power distribution equipment covered in whole or part by this standard.
NOTE 2 The following are common definitions of the hardware with related functions that require additional investigation to the appropriate Canadian and U.S. standards:
– Industrial Control Panel: An assembly of two or more components consisting of one of the following:
- power circuit components only, such as motor controllers, overload relays, fused disconnect switches, and circuit breakers;
- control circuit components only, such as pushbuttons, pilot lights, selector switches, timers, switches, control relays; or
- a combination of power and control circuit components.
These components, with associated wiring and terminals, are mounted on or contained within an enclosure or mounted on a subpanel. The industrial control panel does not include the controlled equipment.
– Panelboard: a single panel or group of panel units designed for assembly in the form of a single panel, including buses and automatic overcurrent devices, and equipped with or without switches for the control of light, heat, or power circuits; designed to be placed in a cabinet or cutout box placed in or against a wall, partition, or other support; and accessible only from the front.
– Switchboard: a large single panel, frame, or assembly of panels on which are mounted, on the face, back, or both, switches, overcurrent and other protective devices, buses, and usually instruments.
Switchboards are generally accessible from the rear as well as from the front and are not intended to be installed in cabinets.
– Transfer switch: an automatic or nonautomatic device for transferring one or more load conductor connections from one power source to another.
– Uninterruptible Power Supply: a power supply used to provide alternating current power to a load for some period of time in the event of a power failure.
