1 Scope

1.1 These requirements cover self-contained, payment-accepting, vending machines. that vend non-refrigerated products to be employedVending machines covered by these requirements are intended for connection to alternating- or direct-current circuits rated 600 V or less in accordance with ANSI/NFPA 70 and:. Vending machines as covered by this standard are intended for indoor use only, except that they will be investigated for outdoor use or use in a protected location if so designated by the manufacturer. Vending machines may be battery operated and may be provided with a solar photovoltaic (PV) system. If a vending machine vends a non-refrigerated product but is provided with a refrigerated section, then the refrigerated section shall be evaluated to the relevant requirements in UL 541.
