5.23 INTERACTIVE SYSTEM – A solar photovoltaic system providing power to a vender and operating in parallel with and may deliver power to an electrical production and distribution network. 5.24 INVERTER – Equipment that is used to change voltage level or waveform, or both, of electrical energy and typically changes dc input to an ac output. 5.25 LOW-VOLTAGE CIRCUIT – A low-voltage circuit is one involving a potential of not more than 30 volts alternating current, 42.4 volts peak or direct current, and supplied by a standard Class 2 transformer or by a suitable combination of transformer and fixed impedance having output characteristics in compliance with those required for a Class 2 transformer. 5.26 MAXIMUM OPERATING CURRENT (MOC) – The current resulting when an electric motor and adjustable speed drive or drive system are operated under any conditions such as maximum speed/maximum load, maximum speed/minimum load, minimum speed/minimum load, minimum speed/maximum load, including locked-rotor such that current to the motor/adjustable speed drive or drive system is at a maximum. 5.27 MAXIMUM RATED CURRENT (MRC) – The current resulting when a hermetic refrigerant motor-compressor and adjustable speed drive or drive system are operated under any conditions such as maximum speed/maximum load, maximum speed/minimum load, minimum speed/minimum load, minimum speed/maximum load, including locked-rotor such that current to the motor-compressor/ adjustable speed drive or drive system is at a maximum. 5.28 MODULE – A complete, environmentally protected unit consisting of solar cells, optics, and other components, exclusive of a solar tracker mechanism, designed to generate dc power when exposed to sunlight. 5.29 MOTOR CONTROLLER – Any device normally used to start and stop a motor, such as a switch, thermostat, pressure limiting control, or the like. 5.30 NONAUTOMATIC VENDER – A vender which delivers a product by requiring the customer to operate the vending mechanism by moving a lever, knob, bottle, or the like.
5.31 NONFUNCTIONAL PART – A part of the equipment that does not perform a specific function. 5.32 NONFUNCTIONAL PART, SMALL – A nonfunctional part having an area of less than 1 ft 2 (0.093 m 2 ) located so it cannot propagate flame from one area to another, and does not connect a possible source of ignition to the other ignitable parts. 5.33 PROTECTIVE ELECTRONIC CIRCUIT (PEC) – An electronic circuit that prevents a risk of fire, electric shock or injury to persons under abnormal operating conditions. ©IEC This definition is reproduced from IEC 60335-1 , Ed. 5.1 b:201 3 with permission of the American National Standards Institute (ANSI) on behalf of the International Electrotechnical Commission. All rights reserved. 5.34 ROUTE PERSON – The person who regularly opens a vender for such purposes as cleaning, inserting/removing currency or coins, replenishing the product supplied, and making minor adjustments. 5.35 SERVICE PERSON – The person who may periodically open a vender to repair or maintain electrical and mechanical components. 5.36 SOLAR PHOTOVOLTAIC (PV) SYSTEM – The total components and subsystems that, in combination, convert solar energy into electric energy suitable for connection to a load such as a vender. 5.37 STAND-ALONE SYSTEM – A solar photovoltaic system that supplies power independently of an electrical production and distribution network. Such a system is not intended to be connected to an electrical production and distribution network.
