CPD Series Data Sheet
200 – 250 Watt CompactPCI
DC-DC Converters
Installation Instructions
These converters are components, intended exclusively for
installation within other equipment by an industrial
assembly process or by a professionally, competent
person. Installation must strictly follow the national safety
regulations in respect of the enclosure, mounting,
creepage distances, clearance, casualty markings, and
segregation requirements of the end-use application.
Connection to the system shall be made via the mating
female connector (see fig. 15). Other installation methods
may not meet the safety requirements. Check for
hazardous voltages before altering any connections.
The converters are provided with a leading pin no. 45,
which is reliably connected to the case. For safety reasons
it is essential to connect this pin to the protective earth of
the supply system, see also:
Safety of Operator-Accessible
Output Circuits.
The Vi input (pin no. 46) is internally fused. This fuse is
designed to protect the converter in case of over current,
but may not be able to satisfy all customer requirements.
External fuses in the wiring to one or both input pins (no. 46
and/or no. 47) may therefore be necessary to ensure
compliance with local requirements.
Important:
If the inhibit function is not used, pin
39 (i) should be left unconnected to enable the
outputs. Enable Pin 27 (EN#) should be
connected to pin 22 (RTN) to enable the outputs.
Do not open the converters, or the warranty
will be invalidated. 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. The maximum specified case
temperature
T
C max
should not be exceeded.
Make sure that a converter failure (e.g., by an internal
short-circuit) does not result in a hazardous condition.
Cleaning Agents
The power supplies are not hermetically sealed. In order to
avoid possible damage, any penetration of cleaning fluids
is to be avoided.
NUCLEAR AND MEDICAL APPLICATIONS - Power-One products are not designed, intended for use in, or authorized for use as
critical components in life support systems, equipment used in hazardous environments, or nuclear control systems without the
express written consent of the respective divisional president of Power-One, Inc.
TECHNICAL REVISIONS - The appearance of products, including safety agency certifications pictured on labels, may change depending
on the date manufactured. Specifications are subject to change without notice.
Standards and Approvals
The converters correspond to class I equipment.
All converters are UL-recognized according to UL 60950
and CAN/CSA C22.2 No. 60950, and approved by TüV
to IEC/EN 60950-1:2001. The following considerations
have been made during design concerning safety :
Build-in component
Basic insulation between input and output, based on
75 VDC. The input is identified as TNV-2.
Operational insulation between output(s) and case
Use in a pollution degree 2 environment.
The converters are subject to manufacturing surveillance
in accordance with the above mentioned UL standards
and ISO 9001:2000.
Isolation
The electric strength test is performed as factory test in
accordance with EN 50116 and EN/IEC 60950 and
should not be repeated in the field (see table
Isolation
).
Power-One will not honour any guarantee claims
resulting from electric strength field tests.

According to IEC/EN 60950, subassemblies connecting input to output
are pre-tested with
≥
3 kVDC.
Protection Degree
The converters correspond to protection degree IP 20,
provided that the female connector is fitted.
Safety of Operator-Accessible Output Circuits
If the output circuit of a DC-DC converter is operator-
accessible, it shall be a SELV circuit according to the
IEC/EN 60950 related safety standards.
However, it is the sole responsibility of the installer to
ensure the compliance with the relevant and applicable
safety regulations.
