Personnel are not able to enter the enclosure, other than reaching in to access components for maintenance purposes.

(10) The definition of an ENERGY STORAGE SYSTEM COMMISSIONING has been added to clarify multiple references in the code. This definition has been added to read: ENERGY STORAGE SYSTEM COMMISSIONING. A systematic process that provides documented confirmation that an energy storage system functions according to the intended design criteria and complies with applicable code requirements.

(11) The definition of an ENERGY STORAGE SYSTEM, ELECTROCHEMICAL has been added to clarify multiple references in the code. This definition has been added to read: ENERGY STORAGE SYSTEM, ELECTROCHEMICAL. An energy storage system that stores energy and produces electricity using chemical reactions.
