Safety Considerations
For safety-agency approval of the system in which the power
module is used, the power module must be installed in com-
pliance with the spacing and separation requirements of the
end-use safety agency standard, i.e., UL60950, CSA C22.2
No. 60950-00, and
VDE 0805:2001-12 (IEC60950, 3rd Ed).
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV),the input
must meet SELV requirements.
The power module has ELV (extra-low voltage) outputs
when all inputs are ELV.
The input to these units is to be provided with a maximum
10A normal-blow fuse in the unearthed lead.
If an input electrolytic capacitor is to be used, it should be
selected using the design information found in the Design
Considerations section.
