INSTALLATION
Connection to the system shall only be effected with cables with suitable wire section or mating connectors (option K).
The auxiliary connector shall be connected via the suitable female connector.
Other installation methods may not meet the safety requirements.
Pin “PE” on input connector is reliably connected to the case. For safety reasons it is essential to connect this pin to the protective earth.
Do not open the converters, or the warranty will be invalidated.
For more details refer to Product datasheet / Accessories datasheets (application notes) at belfuse.com/power-solutions and go to the
respective product or family part number listing.
CLEANING LIQUIDS AND PROTECTION DEGREE
The converters are not hermetically sealed. In order to avoid possible damage, any penetration of liquids shall be avoided.
The converters correspond to protection degree IP 30.
CAUTIONS
These converters are components, intended exclusively for inclusion 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,
clearances, markings and segregation requirements of the end-use application.
This is a Class A product. In a residential environment this product may cause radio interference in which case the user may be required to
take adequate measures.
CAUTION:
Hot Surface – To reduce the risk of injury avoid coming into contact with a hot surface.
Surface chaude – Pour réduire le risque de blessure, évitez d'entrer en contact avec une surface chaude.
PROTECTIVE EARTHING
There’s a protective earth (PE) pin available on input connector.
FUSING
The railway standard EN 50155 does not recommended fuses in the converters. Consequently, the installer must preview an external fuse or
circuit breaker. However, when this is not possible, an incorporated fuse is available (option F). This fuse is not accessible and will not trip,
except if the converter is defect. The type of the incorporated fuses is specified in table. Such fuses are also recommended for external
fuses.
