Isolation
The electric strength test is performed in the factory as routine
test in accordance with EN 50116, IEC/EN 60950 and UL 1950
and should not be repeated in the field. Power-One will not
honor any guarantee claims resulting from electric strength field
tests.
LS-models Operated at Greater than 63 Hz
Above 63 Hz the earth leakage current may exceed 3.5 mA, the
maximum specified in IEC/EN 60950. The built-in Y-caps are
only approved for
≤ 100 Hz. Frequencies greater than 350 Hz
are only permitted for Vi ≤ 200 VAC.

Standards and Approvals
The converters are UL recognized according to UL 1950,
CAN/CSA C22.2 No. 950-95, and TV approved to IEC/EN
60950 standards.
The converters correspond to Class I equipment and have been
evaluated for:
Building in,
Basic insulation between input and case based on 250 V and
double or reinforced insulation or an earthed part between
input and output.
The use in a pollution degree 2 environment,
Connecting the input to a primary or secondary circuit which
is subject to a maximum transient rating of 2500 V.
The converters are subject to manufacturing surveillance in
accordance with the above mentioned UL and ISO 9001:2000
standards.
Railway Applications
The S Series converters have been designed according to
the Railway Standards EN50155 and EN50121. All boards
and components are coated with a protective lacquer.
Cleaning Agents
In order to avoid possible damage, any penetration of
cleaning fluids must be prevented, since the power
supplies are not hermetically sealed.
Protection Degree
Condition: Female connector fitted to the converter.
IP 30:
All models except those with option P and option
D,
or V with potentiometer.
IP 20:
All models exhibiting a potentiometer.
