31、hold and commercial use, for permanent connection to the plumbing of the building. They are intended for either permanent connection to the electrical supply or are factory-provided with a cord terminating in an attachment plug, and are intended for installation and use in accordance with the Nation
32、al Electrical Code, NFPA 70. 1.2 These requirements do not cover portable cord-connected hydromassage equipment, which is covered by the Standard for Personal Hygiene and Health Care Appliances, UL 1431, or hydrotherapy tubs, which are covered by the Standard for Medical Electrical Equipment, Part 1
33、: General Requirements for Safety, UL 60601-1. 1.2 revised March 23, 2010 1.3 The majority of the requirements in this Standard address complete hydromassage bathtubs, including eld-installed accessories.

39、ectrical component that is intended to be attached to the main equipment in the eld or that may be shipped separately from the main equipment. 5.5 CLASS 2 CIRCUIT A secondary circuit with an open circuit potential of no more than 30 volts rms (42.4 volts peak) supplied by either an inherently limite
40、d Class 2 transformer or by a transformer and xed impedance that together comply with all performance requirements for inherently limited Class 2 transformers in the Standard for Low Voltage Transformers Part 1: General Requirements, UL 5085-1, and the Standard for Low Voltage Transformers Part 3: C
41、lass 2 and Class 3 Transformers, UL 5085-3. 5.6 CONFORMAL COATING An insulating coating that conforms to the conguration of the object that is coated. The coating is used as a covering to protect against environmental conditions. 5.6.1 CONTROL, AUTOMATIC ACTION A device in which the transmission and
42、 operation of at least one function is produced by initiation which is not the result of manual actuation. 5.6.1 added August 23, 2011 5.6.2 CONTROL, AUXILIARY A device that provides a functional utility but is not relied on as an operational or protective control. The failure of an auxiliary contro
43、l generally does not cause the operation of a protective control. An example of an auxiliary is one that controls the “on/off” state of bathtub lighting. 5.6.2 added August 23, 2011 5.6.3 CONTROL, MANUAL A device that requires direct human interaction to activate or test the control. 5.6.3 added Aug
44、ust 23, 2011 5.6.4 CONTROL, OPERATING A device that starts or regulates the operation of an appliance during normal operation. The failure of an operational control generally causes the operation of a protective control. An example of an operating control is a temperature regulating control a contro
45、l that maintains the temperature of the bathtub water to a user-determined level. 5.6.4 added August 23, 2011 AUGUST 23, 2011 HYDROMASSAGE BATHTUBS - UL 1795 8UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 5.6.5 CONTROL, PROTECTIVE A device

During the evaluation of the protective control / circuit, the protective functions are veried under normal and single-fault conditions of the con
47、trol. 5.6.5 added August 23, 2011 5.6.6 CONTROL, TYPE 2 ACTION The actuation of an automatic control (see 5.6.1) for which the manufacturing deviation and the drift of its operating value, operating time, or operating sequence have been declared and tested under the Standard for Automatic Electrical
48、 Controls for Household and Similar Use, Part 1: General Requirements, UL 60730-1. 5.6.6 added August 23, 2011 5.6.7 CONTROL, TYPE 2.D.H ACTION This action is applicable to manual controls (see 5.6.3). The automatic action (i.e. tripping of the control) is independent of the manipulation or position
49、 of the manual reset/adjustment mechanism. The manipulation of the manual adjustment means will not allow for the reverse operation (resetting of a tripped control), even momentarily, while the excess or fault condition persists. This action is also referred to as trip-free action. The action of the control is such that the reverse operation (resetting) is possible if the manual reset mechanism is held in the reset position i.e. the control will function as an automatic con
