2 components
2.1 Solid-state controllers shall comply with the Standard for Power Conversion Equipment, UL 508C, orthe Standard for Adjustable Speed Electrical Power Drive Systems – Part 5-1: Safety Requirements .Electrical,Thermal and Energy. UL61800-5-1.
3 Units of Measurement
3.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory orapproximate information.
4 Undated References
4.1 Any undated reference to a code or standard appearing in the requirements of this standard shall beinterpreted as referring to the latest edition of that code or standard.
5 Glossary
5.1 For the purpose of this Standard, the following definitions apply.
5.2 CYCLOALIPHATIC EPOXY – Epoxy resin consisting of two components that react with each otherforming a hard, inert material. Cycloaliphatic epoxies (where “cycloaliphatic” is used as the curing agent)are noted for higher resistance to moisture and UV breakdown compared with non-cycloaliphatic epoxies.
5.3 FORM wOUND MACHINE – A rotating electrical machine using insulated rectangular shapedconductors that are wrapped with additional electrical insulation over the entire coil prior to insertion andare precisely positioned and formed into coils.
5.4 RANDOM WOUND MOTOR – A motor using insulated round magnet wire conductors in which thewinding turns occupy random positions in a slot.
5.5 RTD/ETD – Resistance Temperature Detector/Embedded Temperature Detector installed within themachine near the windings to measure temperatures (when used as a measurement device for theTemperature test).
7 lnsulation Systems
7.1 Insulation systems shall comprise materials that have been shown by service life experience or testto have suitable thermal endurance when operating at the temperature limit declared.Compliance shallbe demonstrated by one of the following methods:
a) Insulation systems without suitable field experience may be used provided the insulationsystem in question (candidate system) complies with Procedure C- Single-point thermal ageingtest in IEC 61858 – Part 2: Electrical insulation systems – Thermal evaluation of modifications toan established electrical insulation system (ElS)- Part 2: Form-wound EIS, when tested againsta system previously found to be acceptable for service at the rated temperature class;
b)A modified or a new insulation system complying with the requirements of IEC 60034-18-31,Part 18-31: Functional evaluation of insulation systems – Test procedures for form-wound
windings – Thermal evaluation and classification of insulation systems used in rotatingmachines;

8Electrical Insulation
8.1 Materials used to support terminals or live parts other than magnet wire shall be constructed ofmaterials that have been shown by experience or test to have suitable thermal and electrical propertiessuitable for the temperatures measured during intended use.Compliance shall be demonstrated by oneof the following methods:
a) Materials have been evaluated and found acceptable in accordance with the applicable
additional evaluation.
