Mounting the H8 power unit inside an enclosure
Cooling air inlet
The cooling fan takes the air from the back, left, right
side and from the bottom of the converter module.
View from:
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 must be
blocked.
Air entry through the bottom plate
Make sure the converter module gets clean air,
because there is no air filter in front of the converter
fan.
Cooling air outlet
To avoid circulating air inside the enclosure make sure
the exhaust air leaves the enclosure.
Cable entries
The cable entries are symmetric on both sides.
Nevertheless only the entries on the left side should
be used for cables connected to the electronic power
supply (SDCS-POW-H01) or the controller board
(SDCS-CON-H01).
Internal cable ducts are
used for the snubber
cables. Do not use
these cable ducts for
other cables e.g.
process signals!
Use cable ties to fix the
fan cable!

The module must be fixed
at the upper side with the
TMR (Top Mounting Rail).
Fasten all cables, otherwise the air flow
from fan will destroy them!
