Mechanical Installation
4.1
Mounting
In order to guarantee the best possible air circulation for the cooling unit, the servo drive should only
be installed in a vertical position. The vertical installation above other systems or heat producing
units can cause overheating.
4.2
Cautionary Markings
Caution !
Readability of cautionary markings and
instruction labels!
If multiple devices are installed side by side, the cautionary / instruction labels on the side of the
housing are not readable anymore. In this case the additional adhesive labels shipped with the
device must be placed in the cabinet near to the devices.
Example of adhesive warning label
WARNING Hot Surface - Risk of Burn
4.3
Control Cabinet Mounting
Installation should be carried out only in a control cabinet in which the inside is free from dust,
corrosive fumes, gases and 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 anti-condensation heater must be installed. The heater must be SWITCHED OFF during
normal operation.
Automatic switch off is recommended
The servo drives should not be installed in areas which have been classified as dangerous,
unless they have been installed in an approved enclosure and in accordance with applicable
regulations. In such an application double check all aspects of the installation.
Please pay attention during installation of the unit to provide for adequate space and ventilation!

General Rule
:
It is better to place heat-producing devices low in an enclosure to support internal convection and
to spread out the heat. If placing such devices up high is unavoidable, enlarging the upper
dimensions at the expense of height or the installation of fans should be considered.
4.4
Cooling and Ventilation
The digital servo drives are inherently designed to protect against damage which may be caused
due to overheating. A temperature sensor is mounted on the heat sink. When the temperature
reaches a level above >95°C, the unit will be automatically shut-down.
This setting can not be altered.
The cooling of the power module will be assisted as much as possible with an internal fan.
Depending upon the temperature the fan unit will operate at one of two levels, in order to limit
unnecessary wear and potential pollution.
Make sure a cabinet of proper size is selected for adequate air circulation.
If the device is placed and operated in a non-ventilated environment, the case volume of the
specified control cabinet must be calculated in accordance with the following table!
Unit
Volume / Cabinet
638A01..- 638A06..
0,12 m³
638B03..- 638B05
0,15 m³
638B08..- 638B15
0,25 m³
For more specific information, please refer to the information provided by the manufacturer
of the cabinet.
