Clearance and creepage between primary (mains) and secondary circuits according EN
60950-1:2001, clause 2.10.3.2 table 2H and clause 2.10.4 table 2L.
Minimum distances between primary and secondary circuits (f.g. for mains voltage 230 V
AC
):
Clearance = 4 mm
Creepage = 5 mm
Failure to maintain these minimum distances would invalidate the approval.
NOTE: For a host or other expansion cards fitted in the host using or generating voltages
greater than 300 V (rms or dc), advice from a competent telecommunications safety
engineer must be obtained.
If these clearance and creepage distances cannot be provided inside the host due to space
limitations, a dielectric material may be used as a physical insulation barrier. The dielectric
material used in this insulation must have a thickness of at least 0.4mm.
After installation (or implementation) of the Socket Modem inside a host system, it is
recommended that a competent telecommunications safety engineer inspects the
complete system to ensure that safety compliance is maintained.
