These converters are components, intended exclusively for integra�on

into other equipment by an industrial assembly process or by a profes-

sionnaly competent person. Installa�on must strictly follow the safety

regula�ons in respect of the enclosure, moun�ng, creepage and clea-

rance distances, markings of the end-use applica�on.

Connec�on to the system shall be made via appropriate connec�on.

The +Vin is internally fused. This fuse is designed to protect the con-

verter against overcurrent caused by a failure, but may not be able

to sa�sfy all requirements. External fuses in the wiring circuit to one

or both input pins may be necessary to ensure compliance with local

requirements.

Do not open the converters, or the warranty will be invalidated. Make

sure that there is sufficient heat dissipa�on available for conduc�on

cooling. This should be verified by measuring the case of temperature

at the specified measuring point, when the converter is operated in the

end-use applica�on.

Cleaning Agents and Process

The converters are not herme�cally sealed. In order to avoid possible

damage, any penetra�on of liquids shall be avoided.

Isola�on

The electric strength test is performed in the factory in accordance with

IEC/EN 60950.

Standards and Approvals

The converters are built to meet the safety standards IEC 60950-1, EN

60950-1.

‘Built to meet’ men�onned in the different paragraphs of the datasheet

means that Power System Technology has designed the product to

meet the standard but not cer�fied it in a laboratory.

Railway Applica�on

The converters have been designed observing the railway standards

EN 50155 and EN 50121. All boards can be protected by a conformal

coa�ng as an op�on ( -V).
