SAFETY

Constructed in accordance with IEC 60950-1,

EN 60950-1,

and

UL 60950-1,

supplementary

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.
