First Edition, Dated February 26, 1999

SUMMARY OF TOPICS:
This revision of UL 1699 is being issued to add Test Method to requirements for Surge Testing,
clarify requirements for Installation Instructions, include miscellaneous requirements, and revise
requirements for Peak Inrush Current.
UL Standards for Safety are developed and maintained in the Standard Generalized Markup Language
(SGML). SGML -- an international standard (ISO 8879-1986) -- is a descriptive markup language that
describes a document’s structure and purpose, rather than its physical appearance on a page. Due to
formatting differences resulting from the use of UL’s new electronic publishing system, please note that
additional pages (on which no requirements have been changed) may be included in revision pages due
to relocation of existing text and reformatting of the Standard.
Text that has been changed in any manner is marked with a vertical line in the margin. Changes in
requirements are marked with a vertical line in the margin and are followed by an effective date note
indicating the date of publication or the date on which the changed requirement becomes effective.
The following table lists the future effective dates with the corresponding item.
