Note : The TMOV and
i
TMOV varistors are intended, in conjunction with
appropriate enclosure design, to help facilitate TVSS module compliance
to UL 1449, Section 37.4 (abnormal over-voltage limited current require-
ments). Under these extreme abnormal over-voltage 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.
