7.4 Materials employed as electrical insulation in the system shall be resistant to deterioration that would result in an electrical shock, fire or other safety hazard. Insulation materials that are in direct contact with or close proximity to hazardous live parts in accordance with Figure 6.1 of the Material Property Considerations table in the Standard for Polymeric Materials — Use in Electrical Equipment Evaluations, UL 746C, or the Standard for Evaluation of Properties of Polymeric Materials, CAN/CSA-C22.2 No. 0.17, shall additionally meet the insulation criteria outlined in either standard unless employed as part of a component that has been evaluated to a component standard that has comparable safety criteria. Insulated wiring is subjected to the requirements outlined in Section 11.
7.5 Gaskets and Seals relied upon for safety, shall be determined suitable for the environmental conditions and chemical substances they are anticipated to be exposed to in their end use.
8 Metallic Parts Resistance to Corrosion
81 Metallic enclosures shall be corrosion resistant to prevent deterioration that would affect the ability of the enclosure to provide physical protection to EES System components or access to hazardous parts that could result in a hazardous condition. A suitable plating or coating process can achieve corrosion resistance. Additional guidance on methods to achieve corrosion protection can be found in the Standard for Enclosures for Electrical Equipment, Environmental Considerations. UL 50E, or the Standard for Enclosures for Electrical Equipment, Environmental Considerations. C22.2 No. 94.2.
9 Enclosures and Guarding of Hazardous Parts
9.1 The enclosure(s) of an Energy storage system shall have the strength and rigidity required to resist the possible physical abuses that it will be exposed to during its transportation, installation and intended use.
9.2 Openings in the enclosure of an electric energy storage system shall be designed to prevent inadvertent access to hazardous parts. Compliance shall be determined in accordance with the Tests for Protection Against Access to Hazardous Parts Indicated by the First Characteristic Numeral, Clause 12 of the Standard for Degrees of Protection Provided by Enclosures (IP Code), IEC 60529, or the Standard for Degrees of Protection Provided by Enclosures (IP Code), CAN/CSA-C22.2 No. 60529, for a minimum IP rating of IP2X and the Canadian Electrical Code, Part I Safety Standard for Electrical Installations, C22.1, the Enclosure Selection Table for Nonhazardous Locations, Table 65. with consideration of the end use installation.
Exception: An energy storage system intended for restricted access locations need not meet the accessibility criterion if permanent warning markings for service and other personnel having access to the system are provided directly on the system. Protection from access to hazardous live parts in restricted locations shall be in accordance with Article 110 of the National Electrical Code, NFPA 70. or Sections 2 arid 36 of the Canadian Electrical Code. Part I Safety Standard for Electrical Installations, C22. 1, or Section 124 of the National Electrical Safety Code, IEEE C2, as applicable.UL 9540-2016 pdf free download.
