An additional external fuse, suitable for the application,
might be necessary in the wiring to the other line input 26 /
28 (N ~ ) if:
Make sure that there is sufficient airflow available for
convection cooling. This should be verified by measuring
the case temperature, when the converter is installed and
operated in the end-use application; see Thermal
Considerations.
Ensure that a converter failure (e.g., an internal short-
circuit) does not result in a hazardous condition; see also
Safety of Operator-Accessible Output Circuits.
Standards and Approvals
The converters are safety-approved to EN/IEC
60950-1, and UL/CSA 60950-1 2
106 or greater).
The converters correspond to Class I equip-
ment and have been evaluated for:

• Local requirements demand an individual fuse in each
• Phase and neutral of the mains are not defined or
• Neutral and earth impedance is high or undefined
• Building-in
• Basic insulation between input and case based on 250
• Functional insulation between outputs.

All boards of the converters are coated with a protective
lacquer.
The converters are subject to manufacturing surveillance
in accordance with the above mentioned UL standards
and ISO 9001:2000. A CB-scheme is available.
Cleaning Agents
In order to avoid possible damage, any penetration of
cleaning fluids is to be prevented, since the power
supplies are not hermetically sealed.
Protection Degree
Condition: Female connector fitted to the converter.
Leakage Currents
Leakage currents flow due to internal leakage capacitances
and Y-capacitors. The current values are proportional to the
supply voltage and are specified in the table below.
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.
