Fact Sheet
Panel Through Mount accessory
Electronics can be kept separate from cooling air by mounting the
VLT® drive through the back of the cabinet.
Cooling
solution for saving
cabinet space, textile
mills/installation in
dust and u , and
for using external
cooling source
The major part of the generated heat
from VLT® drives is removed via the
heat sink. Mounted through the back
of a panel wall cooling air heat can be
removed without risking damage to the
electronics even if dust, heat, moisture,
or corrosive elements are present.
A second possibility is to mount the
heat sink in a duct, with a cooling air
stream created by external fans either
dedicated for the purpose or part of a
process close to the drive
All parts required to mount a standard
drive through a panel are included in
the kit.
Electronics are kept separate from
cooling air in a closed and protected
environment.
It is possible to impose forced cooling

on the heat sink by adding a back plate
to create a duct for cooling air. This way,
the built-in fan will force cooling air
through the duct.
Frames and enclosures

■ B1, B2, C1, and C2: IP21
Feature Bene t
– Only a minor part of generated heat stays
inside the cabinet
Heat sink of the drive extends into separate
cooling channel
Gasket between heat sink
and electronics side of the drive
Flat, single-piece frame,
with mounting accessories
Built-in fan can be removed
– Reduces the cost of cabinet A/C system
– Less cabinet space (depth) is required
– The drive can be tied into a common
cooling duct system
– Easy maintenance – cooling ribs can be
cleaned without aff ecting the electronics
– Electronics are IP 55 protected against
particles, humidity or aggressive substances
– Easy to mount onto a standard drive
– All parts included in the kit
– Frame can be reversed if mounting from
the back is wanted
– Allows use of external fan or process air
to cool the drive

The back plate (must be purchased
separately) is used if an air duct is not
available.
Mounted in a duct construction the
built-in fan can be removed, and the
cooling air provided by an external fan.
