Constructed in accordance with IEC 60950-1,
EN 60950-1,
insulation, 250Vrms maximum working voltage,
flammability class V-0.
There are no special installation requirements
(beyond attending to usual PCB track separations)
since the integral cover provides supplementary
insulation from its external faces to internal core
and windings.
* If no DC block required, one of these capacitors can be removed and
SAFETY
the other set to 22 F, or, if preferred, both capacitors can be eliminated.
