[Replace with the following]

This part of IEC 61347 specifies particular safety requirements for electronic controlgear for use on d.c. supplies up to 380 V and a.c. supplies up to 600 V at 50 Hz or 60 Hz and at an output frequency that can deviate from the supply frequency, associated with LED modules.

Note 1A: A lamp controlgear for LED modules may also be referred to as “LED controlgear”, “LED driver”, “LED power supply”, or similar wording associated with “LED”.

Note 2A: Requirements for self-ballasted LED modules intended for connection using interchangeable dedicated connection interface (IDCI) that do not employ ANSI standard base configurations are specified in Annex CB DB of CAN/CSA-C22.2 No. 62031.

Note 3A: A non-electronic lamp controlgear for LED modules is also covered by specific requirements of this Standard. The phrase “electronic lamp controlgear” is understood to also apply to a “non-electronic lamp controlgear”.

This Standard applies to the safety of such equipment designed to be installed on branch circuits not exceeding 600 V nominal or less between conductors in accordance with the Canadian Electrical Code (CEC), Part I, and also for connection to additional isolated power sources such as batteries, generators, solar cells, and fuel cells.

The object of this Part 2 Standard is to specify general electrical safety requirements for LED controlgear. The requirements of this Standard apply to a specific end use product when it is explicitly referred to by that product standard. Each individual product standard may supplement, modify, or omit a general rule of this Part 2 Standard to provide the relevant requirements for each type of product.

The annexes of CAN/CSA-E61347-1 that are applicable according to this Part 2 Standard and that use the word “lamp” are understood to also apply to LED modules.

Particular requirements for SELV controlgear are given in Annex I.

Plug-in controlgear, being part of the luminaire, are covered as for built-in controlgear by the additional requirements of the luminaire standard CSA C22.2 No. 250.0.

1  Scope

[Replace this clause with the following]

1.1
This Standard specifies general and safety requirements for:

non-integrated light-emitting diode (LED) modules without integral controlgear (LEDni modules) and semi-integrated LED modules (LEDsi modules) for operation under constant voltage, constant current, or constant power; and self-ballasted Integrated LED modules (LEDi modules) with integral controlgear for use on dc supplies up to 250 V or ac supplies up to 347 V.

LED modules within the scope of this document can be integral, built-in or independent.

This document is not applicable for LED lamps.

1.2
This Standard applies to units for use in non-hazardous locations that are intended to be installed or used in accordance with CSA C22.1, Canadian Electrical Code (CEC), Part I, and also to units that are intended for connection to isolated (non-utility connected) power sources such as generators, batteries, fuel cells, solar cells, and ac/dc converters.

1.3
Requirements for LED light enginemodules, intended for connection to a circuit described in 1.1 b), are specified in Annex DB.

Note 1: The safety requirements for separate controlgear are specified in CAN/CSA-C22.2 No. 61347-2-13.

Note 2: In the requirements of this Standard, where both types of LED modules, integrated modules, and modules with external controlgear are addressed, the term “modules” is used instead. The term “LED module(s)” is used to denote modules without external controlgear. The term “integrated LED module(s)” is used to denote modules with internal controlgear.

1.4
The values given in SI units are the standard. Where values are given in parentheses, they are for information only.

1.1

The CSA B64 Series covers vacuum breakers and backflow preventers that are used in potable water supply systems to prevent cross‑connections.

1.2

This Standard specifies definitions, general requirements, test methods, markings, and instructions that are common to some or all of the CSA B64 Series.

1.3

This Standard is not a complete Standard in itself and is intended to be used in conjunction with one of the Standards in the CSA B64 Series to form a complete Standard for a particular type of vacuum breaker or backflow preventer.

1.4

In CSA standards, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.

1.5

This Standard is written in SI (metric) units; for conversion tables, see Annex A. Vacuum is expressed in pressure below ambient. All pipe sizes are shown as nominal pipe sizes (NPS).

1.1
This Standard specifies the framework and calculation models for “essential energy benchmarking” of data centres as a new form of ideal-state benchmarking for energy performance. It provides the specifications necessary to benchmark the energy efficiency performance of a data centre by using a dimensionless indicator called the benchmark energy factor (BEF).

This Standard is a reference document for the application of essential energy benchmarking to data centres. The essential energy model is based on best available technology (BAT) and fundamental thermal, mechanical, electrical, and/or work-load components. The BAT is determined independent of cost and, in most cases, independent of the equipment that is currently in use within a data centre that is using this Standard. Exceptions are provided for when a data centre is using IT equipment that is not covered by the essential energy models.

This Standard applies to the use of electrical energy for the data centre.

Data centres that are included within the scope of this Standard include data centres with a minimum IT load of 100 kW that are typically used in enterprises, government, institutional (hospital and University), and other facilities where the organization has influence over the equipment and a vested interest in the energy consumption of the data centre. This may include third-party managed data centres when the above conditions are met.

1.2
Specifically excluded from the scope of this Standard are the following:

  a) colo data centres – given that the data centre operator does not usually have control over the IT equipment or the software environment;

  b) telco data centres – given that the majority of equipment is specialized hardware equipment that are not currently supported by the essential energy models; and

  c) data centres that have the cost of electricity embedded in the rent – given that there is no direct financial benefit to improving the energy efficiency of the data centre.

1.3
In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.

At time of writing, this Standard does not include surface water, groundwater, detailed snow, glacier mass balance and air quality monitoring equipment. Further, this Standard excludes less commonly used instrumentation such as acoustic Doppler radars, mini-weather radars, SODAR wind profilers and ceilometers, as well as manually operated instrumentation.
