1
The front end output voltage should match the specified input voltage range of the DC-DC converter.
2
The earth connection has to be provided by the installer according to the relevant safety standard, e.g. IEC/EN 60950.
3
The installer shall provide an approved fuse (type with the lowest rating suitable for the application) in the non-earthed input line di-
rectly at the input of the DC-DC converter (see fig.: Schematic safety concept). For UL
’
s purpose, the fuse needs to be UL-listed. See
also: Input Fuse
4
Each suppressor diode should be dimensioned in such a way, that in the case of an insulation fault the diode is able to limit the output
voltage to SELV (<60 V) until the input fuse blows (see fig.: Schematic safety concept).
5
Has to be insulated from earth by basic insulation according to the relevant safety standard, based on the maximum output voltage
from the front end.
Accessories
Mounting supports for chassis and DIN-rail mounting.
Option C
The C-pinout configures the electrically isolated double out-
puts to the "industrial pinout" Vo1+, Vo2
–
with common
ground Go. With the C-pinout the converter height is in-
creased by the adapter PCB (see also: Mechanical Data).
