4 Mechanical installation
4.1 Mounting
Eurotherm digital servo drives may be installed only in a vertical position to guarantee the best air
circulation for the cooling ribs of the heat sink. Vertical installation above other drive racks or above other
heat producing devices can lead to overheating. In addition the drives are to be operated exclusively in
Eurotherm racks or the compact enclosure respectively.
4.2 Control cabinet - mounting
Installation should be carried out only in a control cabinet in which the inside must be free from dust,
corrosive fumes, gases, and all liquids.
Make absolutely sure that the condensing of evaporating liquids including atmospheric moisture, is
avoided. Should the digital servo drive be installed in a place where condensation is likely, a suitable
anticondensation heater must be installed. The heater must be SWITCHED OFF during normal operation.
Automatic switch off is recommended
Eurotherm-digital servo drives should not be installed in are as which have been classified as dangerous, if

General rule :
It is better to place heat-producing devices low in an enclosure to support internal convection and
to spread the heat. If placing such devices up high is unavoidable, enlarging the upper dimensions
at the expense of height or installing fans should be considered.
4.3 Cooling
The digital servo drives are protected against damages caused by overheating.
There is a thermal sensor installed on the heat sink. When the temperature rises to >95°C,
the drive is automatically switched off. This setting cannot be changed.
Make sure a cabinet of proper size is selected for adequate air circulation
If the device becomes operated in a not ventilated device, the case volume of the specified
control cabinet must be calculated in accordance with the following table !
Gerät Volumen/Schaltschrank
637+/D6R02...D6R10 0,12 m³
