are intended, in conjunction with appropriate enclosure
design, to help facilitate TVSS module compliance to
overvoltage conditions, the units will exhibit substantial
heating and potential venting prior to opening. Modules
should be designed to contain this possibility. Application
testing is strongly recommended.
