PSS, PSK Extended Data Sheet
Positive Switching Regulator (Rugged)
REV. FEB. 25 2004
Page 13 of 18
Standards and Approvals
All switching regulators are UL recognized according to
UL 60950, CAN/CSA C22.2 No. 234-M90 and IEC/EN
60950.
The units have been evaluated for:
Building in
Operational insulation from input to output and input/out-
put to case
The use in a pollution degree 2 environment
Connecting the input to a secondary circuit which is sub-
ject to a maximum transient rating of 1500 V
The switching regulators are subject to manufacturing sur-
veillance in accordance with the above mentioned UL,
CSA and ISO 9001 standards.
Safety of Operator Accessible Output Circuit
If the output circuit of a switching regulator is operator-ac-
cessible, it shall be an SELV circuit according to IEC/EN
60950 related safety standards.
The following table shows some possible installation con-
figurations, compliance with which causes the output circuit
of the switching regulator to be an SELV circuit according to
IEC/EN 60950 up to a configured nominal output voltage of
30 V, or 48 V if option C is fitted.
However, it is the sole responsibility of the installer or user
to assure the compliance with the relevant and applicable
safety regulations.
Installation Instruction
Installation of the switching regulators must strictly follow
the national safety regulations in compliance with the enclo-
sure, mounting, creepage, clearance, casualty, markings
and segregation requirements of the end-use application.
Check for hazardous voltages before altering any con-
nections.
The input and the output circuit are not separated. i.e. the
negative path is internally interconnected!
The units should be connected to a secondary circuit. Do
not open any module. Ensure that a unit failure (e.g. by an
internal short-circuit) does not result in a hazardous condi-
tion. See also
:Safety of operator accessible output circuit.
Note: Additional information on input circuitry, grounding
and parallel operation of units is given in:
Technical Infor-
mation: Application Notes.
Protection Degree
The protection degree is IP 30 (equipped with option P: IP
20). It applies only if the module is plugged-in or the female
connector is properly attached to the module.
Isolation
Electric strength test voltage between input interconnected
with output and case: 1500 VDC, 1 s. This test is performed
in the factory as routine test in accordance with IEC/EN
60950 and UL 60950 and should not be repeated in the
field. Power-One will not honour any guarantee claims re-
sulting from electric strength field tests.

Connector Pin Allocation
The connector pin allocation table defines the electrical
potentials and the physical pin position on the connector.
Pin 24 (protective earth) is a leading pin, which provides
electrical contact first. The modules should only be wired
via the female connector H15 (according to DIN 41612) to
ensure requested safety!
