When installed in an end-product, consideration must be given to the following:
CF1.3
The end-product Electric Strength Test is to be based upon a maximum working voltage of:
Input-Output: 106 Vrms, 220 Vpk
CF1.5
The following secondary output circuits are SELV: All outputs
CF1.7
The following secondary output circuits are at non-hazardous energy levels: All outputs
CF1.11
The power supply terminals and/or connectors are: Suitable for factory wiring only
CF1.13
The investigated Pollution Degree is: 2
CF1.19
The following end-product enclosures are required: Fire, Electrical, Mechanical
CF2.0
The Unit is considered as functional insulation and intended to be installed in isolated secondary
circuit which is seperated from primary circuit by Reinforce or Double insulation; additional tests
of Humidity Test should be considered in the end product.
CF2.1
Abnormal/Component Failure Tests were conducted with an external fuse (T2.0A for x = 1002,
1003, 1006, 1007, 1008; T1.0A for x = 1012, 1013, 1017, 1016, 1018; T0.5A for x = 1022, 1023,
1026, 1027, 1028, 1032, 1033, 1036, 1037, 1038). Repeated tests in the end-use appliance shall
be considered for installing different rated protective devices.
CF2.2
Special spacing consideration should be given to the end-use product as the spacings between
the unit and mounting surface have not been evaluated.
CF2.3
The DC/DC Converter with potting compound has been tested according to sub-clause 5.2.2.
The actual test voltage was DC 5600 V by manufacturer's request.
CF2.4
The DC/DC Converter shall be installed in compliance with the enclosure, mounting, spacing,
casualty, markings and sepregation requirements of the end use application.
CF2.5
The DC/DC Converter has not been evaluated for patient connected applications.
CF2.6
The need for conducting Leakage Current Tests should be considered as part of the end product
evaluation.
