SUN - UL 61800-5-1, Standard for Safety for Adjustable Speed Electrical Power Drive Systems
Effective July 18, 2016
Effective Date (see Schedule below): July 18, 2016
Impact Statement: A review of all Listing Reports is necessary to determine which products comply with new/revised requirements and which products will require re-evaluation. NOTE: Effective immediately, this revised standard will be exclusively used for evaluation of new products unless the Applicant requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date of July 18, 2016 unless the product is found to comply with new/revised requirements.
Overview of Changes: Clarification of Requirements for Functional Insulation, Impulse Test and Partial Discharge Test for Solid Insulating Materials, Generic Materials for Direct Support of Live Parts and Generic Materials Used as Insulating Barriers in Lieu of Spacings. Specific details of new/revised requirements are found in table below.
Schedule: So that production of products bearing Listing Marks will not be interrupted, the following schedule of approximate dates has been established to ensure Listing Reports are found compliant by Effective Date:
- November 17, 2015 = 8 Month Report Review – Intertek will review all Reports. Update if compliance is verified or issue Findings Letter/Quote for any re-evaluations needed
- January 15, 2016 _ = 6 Month Quote Cut-off – Quotes returned for necessary re-evaluations
- June 17, 2016 = 30 Day Warning – Client advised of all non-compliant Reports to be Suspended
- July 18, 2016 = Effective Date – ATM Suspended for all non-compliant Reports
Fees: An initial review of Listing Report (s) will be covered by a direct billing project and will be invoiced at not more than $1000 per report.
Client Action Required:
Information - To assist our Intertek Engineer with review of your Certification Reports, please submit technical information in response to the new/revised paragraphs noted in the attached or explain why these new/revised requirements not apply to your product (s).
Current Listings Not Active? – Please immediately identify any current Listing Reports or products that are no longer active and should be removed from our records. We will do this at no charge as long as Intertek is notified in writing prior to the review of your reports.

| 4.4.2.2DV D2 Modification to replace 4.4.2.2 | 4.4.2.2DV D2 Modification to replace 4.4.2.2 with the following: 4.4.2.2DV.1 Other than as noted in 4.4.2.2DV.2 through 4.4.2.2DV.7.1, a material that is used for the direct support of an uninsulated LIVE PART shall comply with the Flammability, Relative Thermal Index (RTI), Hot Wire Ignition (HWI), High-Current Arc Resistance to Ignition (HAI), and Comparative Tracking Index (CTI) values indicated in Table 4.4.2.2DV.1. A material is in direct support of an uninsulated LIVE PART when:
b) It serves to physically support or maintain the relative position of the uninsulated LIVE PART. | |
| 4.4.2.2DV.7.1 | 4.4.2.2DV.7.1 No additional evaluation is required for the direct support of uninsulated live parts when the generic materials used comply with Table 14. Each material shall be used within its minimum thickness and its RTI value shall not be exceeded during the Temperature Rise Test of Section 5.2.3.8. | |
| 4.4.4DV.2 | 4.4.4DV.2 Equipment shall be rated for service in an AMBIENT TEMPERATURE of 40°C (104°F) or at a higher or lower AMBIENT TEMPERATURE at an interval from 40°C (104°F) in a whole number multiple of 5°C (9°F), such as 45, 50, 55, 60. | |
| Table 15DV (2) | Table 15DV – Maximum measured temperatures for internal materials and components | |
| 4.15DV.1.7.8 | 4.15DV.1.7.8 The generic insulating materials in Table 4.15DV.1 meet the intent of the requirements for this application without additional evaluation. | |
| Table 4.15DV.1 | Table 4.15DV.1 – Generic materials for barriers | |
| 4.15DV.1.7.9 | 4.15DV.1.7.9 Except as noted in 4.15DV.1.7.10 through 4.15DV.1.7.12, an insulating material shall also comply with the requirements in 4.15DV.1.7.3 when: a) The material is not in direct physical contact with an uninsulated LIVE PART; b) The material does not serve to physically support, or maintain the relative position of that uninsulated LIVE PART; and c) The material is used as a barrier in lieu of the required through air spacings. | |
| B.3DV DE | B.3DV DE Modify to correct: Figure B.11 illustrates the application of functional insulation if the circuit analysis required by 4.2 shows that failure of the insulation could not result in a hazard. If the analysis required by 4.2 does show that failure of the insulation could result in a hazard, functional insulation shall meet the requirements and tests for basic insulation. |
