Mounting the converter module D7 inside an enclosure
Cooling air entry
The cooling fan takes the air from the backside, both
sides and from the area underneath the converter
module.
Free space around the converter module
Do not place the converter module in a corner. In case
the fan cannot take the air through the bottom plate of
the enclosure none of the remaining entries can be
blocked.
Cable entries
The cable entries are existing symmetrically on both
sides. Nevertheless only the entries on the left side
should be used for cables going to the electronics
power supply (SDCS-POW-1) or the controller board
(SDCS-CON-4).
Screened cable for
hardware interface
connection IOB2/IOB3
board is strongly rec-
ommended
Provide sufficient
grounding of card
holder
Air entry through bottom plate
Make sure the converter module gets clean air,
because there is no air filter in front of the fan at the
converter.
Use cable straps for
fan cable
Cooling air outlet
To avoid circulating air inside the enclosure it is rec-
ommended to make sure the exhaust air leaves the
enclosure.

Do not have loose cables. The air flow from
fan will destroy the cables!
Internal cable ducts
are used for snubber
circuit wiring. Don’t
use these cable
ducts for other
cables or process
signals.
