S1 is used to simulate the interchanging of phase and
neutral. S2, S3 select either the earth or output leakage
current test, S4 selects either the positive or negative output.
Building in
Basic insulation between input and case, based on
250 VAC
Double or reinforced insulation between input and output,
based on 250 VAC
Operational insulation between output and case
The use in a pollution degree 2 environment
Connecting the input to a primary circuit with a maximum
transient rating of 2500 V (overvoltage class III based on a
110 VAC primary circuit, overvoltage class II based on a
230 VAC primary circuit).
The converters are subject to manufacturing surveillance in
accordance with the above mentioned UL standards and with
ISO9001:2000.
For details see the Declaration of Conformity (last page).
Isolation
The electric strength test is performed in the factory as routine
test in accordance with EN 50116 and IEC/EN 60950 and
should not be repeated in the field. Power-One will not honor
any warranty claims resulting from electric strength field tests.

According to EN 50116 and IEC/EN 60950-1, transformers and subassemblies connecting input to output are pretested with 5.6 kVDC or
4.0 kVDC.

according to IEC/EN 60950, Annex D.
Leakage Currents
Leakage currents flow due to internal leakage capacitance and
RFI
suppression Y-capacitors. The
current
values
are
proportional to the input voltage and frequency. They are
specified at maximum operating input voltage, where phase,
neutral, and protective earth are correctly connected, as
required for class I equipment.
Under test conditions, the leakage current flows through a
measuring instrument (MI) as described in the fig. below, which
takes into account impedance and sensitivity of a person
touching unearthed accessible parts. The current value is
calculated by dividing the measured voltage by 500
. If inputs
and/or outputs of converters are connected in parallel, their
individual leakage currents are added.
