UL-10001:2017 pdf free download – For preparing an Environmental Product Declaration (EPD) for the Product Category: POWER INVERTER PRODUCTS.
2.1. System Function
The function of a power inverter is to use an output signal to control the operation of a motor, typically integrated in a system of equipment that delivers services such as water treatment and building air conditioning and heating. This PCR uses a cradle to gate with options scope with a declared unit or, when the power inverter application is known, a cradle to grave scope with a functional unit. Section 2.2 discusses these units and defines them for the power inverter product category.
2.2. Declared or Functional Unit
The declared or functional unit of a product provides the basis for quantitative normalization and reporting of a reference unit. A declared unit is used when the precise application at the time of product use is unknown. Where there is an applicable standard characterizing product performance that affects the use phase, that standard will be referenced per Section 8.
Declared Unit
The declared unit is a single, commercial, functioning power inverter unit capable of controlling a utility system by varying its output current, voltage, and frequency over a wide range of loads. The scope of an EPD created using a declared unit shall be cradle to gate with options, illustrated in Figure 1.
Functional Unit
When the application is known, a power inverter functional unit shall be used that delivers control of a utility system over a period of 750,000 operational hours by varying its output current, voltage, and frequency. The scope of an EPD created using a functional unit shall be cradle to grave, illustrated in Figure 1.
The product shall be classified based on input voltages:
• Low voltage (<1 kV AC 50 Hz or 60 Hz and/or voltages up to and including 1.5 kV DC input side) • Medium voltage (>1kv AC 50 or 60Hz and/or voltages above and not exceeding 1.5kV- 35kV DC input side)
The partial load efficiency class and related electrical power losses of the power inverter (lE classification) shall be reported according to the EN 50598-2 standard.
Standards specifying the ratings, performance, installation and operation specifications and relevant tests shall be referenced and are included in Section 8.
The raw material supply module (Al) includes the provision of all raw materials and energy and includes waste processing or disposal of final residues during the material acquisition stage. It also includes all flows related to electricity generation of all processes in the product stage. However, production of capital goods, infrastructure, production of manufacturing equipment and personnel-related activities are not included.
The raw material supply stage will account for:
• Extraction and processing of raw materials (e.g., mining and refining processes) and biomass production and processing (e.g., agricultural or forestry operations);
• Reuse of products or materials from a previous product system;
• Processing of secondary materials used as input for manufacturing the product, but not including those processes that are part of the waste processing in the previous product system
• Generation of electricity, steam and heat from primary energy resources, also including their extraction, refining and transport;
• Energy recovery and other recovery processes from secondary fuels, but not including those processes that are part of waste processing in the previous product system;
3.1.2. Transport (A2)
The transport module (A2) includes the transportation of all raw and packaging materials to manufacturing.
The manufacturing module (A3) includes the manufacturing of raw materials into the finished, packaged power inverter. This includes all materials, products, and energy and includes waste processing or disposal of final residues during the product stage. However, production of capital goods, infrastructure, production of manufacturing equipment and personnel-related activities are not included. HVAC (heating, ventilation, and air conditioning), artificial lighting and transport within the manufacturing site should be included.
The manufacturing will account for:
• Generation of electricity, steam and heat from primary energy resources, also including their extraction, refining and transport.
