Safety and Installation Instructions
Terminal Allocation
The terminal allocation tables define the electrical potential
of the converters.

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).
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.
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
