Positive Switching Regulator (Industrial)
REV. FEB 25, 2004
Page 14 of 19
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 750 V.
The switching regulators are subject to manufacturing sur-
veillance in accordance with the above mentioned UL,
CSA and ISO 9001 standards.
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 connec-
tions.
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.

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
