Specifications

MCD3000 Series
6 MG.15.A4.22 - VLT is a registered Danfoss trademark
Installation
■ Mechanical installation
Models MCD3007~3132 have an IP21 rating and can
be wall mounted or installed inside another enclosure.
These models can be mounted side by side with no
clearance.
Models MCD3185~3800 have an IP20 rating and
must be mounted in another enclosure. These models
must have a clearance of 100mm on either side.
ATTENTION
Do not mount in direct sunlight or near heat
radiating elements.
■
Ventilation
MCD3000 cooling is by means of air circulation.
Consequently, the air needs to be able to move freely
above and below the soft starter.
Soft starters dissipate approximately 4.5 watts per
amp. When installing a soft starter in a switchboard or
other enclosure, ensure there is sufficient airflow
through the enclosure to limit heat rise in the
enclosure.
The table below shows airflow requirements for
selected motor currents.

ATTENTION
If other heat sources are installed in an
enclosure with the MCD3000, this heat must
also be considered when calculating required airflow.
ATTENTION
If the MCD3000 is installed in an enclosure
without ventilation a bypass contactor should
be employed to prevent heat dissipation during run.
