Midi-Maestro and Maxi Maestro Drive

Ventilation
Installing in a sealed enclosure
To maintain sufficient cooling of the Drive when it is
installed inside a sealed enclosure, heat generated by
all the equipment must be taken into account and the
enclosure must be of adequate size.
The Drive must be installed in a vertical position, to
ensure the correct airflow is flowing between the
cooling fins of the heat-sink. Vertical installation
above other Drives or any other heat producing
equipment may result in overheating.
Note
The total power dissipated by Drives, chokes,
transformers and braking resistors is about 12% of the
total of the motor rating.
Drives are protected against overheating. When the
temperature of the heat-sink reaches 95°C, the Drive
is disabled. When the temperature subsequently falls
to below 95°C the Drive is automatically re-enabled.
