Installation Instructions
The converters of the W Series are components, intended
exclusively for inclusion within other equipment by professional
installers. Installation must strictly follow the national safety
regulations in compliance with the enclosure, mounting,
creepage, clearance, casualty, markings and segregation
requirements of the end-use application.
DIN-rail mounting is possible with the built-in snap-fit device
on a DIN-rail. This fulfills the mechanical transport requirements
as per ETSI 300019-1-2, class 2 (vertical).
To fulfill the requirements of IEC 721-3-2, class 2.1 (vertical), 2
additional fixing brackets DMB-EWG [formerly HZZ00624] (see
Accessories) must be fitted on the bottom side of the DIN-rail.
For heavy duty railway applications, we recommend installing
all 4 fixing brackets DMB-EWG.
Wall mounting is possible with the wall-mounting brackets
UMB-W [HZZ00618] (see Accessories). This complies with
IEC 721-3-2, class 2.2 (vertical and horizontal).
The converters of the W Series are class I equipment: Input
terminal 1 ( ) and the output terminals 1 and 11 ( )
are reliably connected to the case. For safety reasons it is

screwdriver) and adequate force.
essential to connect the input terminal 1 ( ) to the protective
earth of the supply system. Output terminals 1 and 11 can be
used to connect the output voltage(s) or the load to functional
earth.
The phase input (L or Vi+) is internally fused; see Input Fuse.
Caution: Install the converters vertically, and make sure that there
is sufficient airflow available for convection cooling. The minimum
space to the next device should be: top/bottom: 30 mm, left/right:
20 mm.
