Hello Craig,
“Continuous energization” as it relates to ITE would be internal electronics generating heat, so that water vapor, giving the choice of condensing inside the cabinet, would choose not to. Notice that there is no wattage requirement given in the standard, so yes, I would say that an ATM machine qualifies.

Would you consider an ATM (Automated Teller Machine) situated outdoors, permanently connected, which is switched off only for some servicing activities as "– providing continuous energization of the enclosed equipment"? If not, what type of equipment would the "– providing continuous energization of the enclosed equipment" apply to?
