iPOS4803 Microdrive EtherCAT Technical Reference
3.4 Mechanical Mounting
The
iPOS4803P
and
iPOS4803PE
Microdrives
are intended to be mounted horizontally on a motherboard equipped
with the recommended mating connectors, as specified in chapter
Motherboard PCB Design. Several drives
can be hosted by a single motherboard.
The
iPOS4803S
Microdrive
is intended to be mounted vertically or horizontally on a metallic support using the
provided mounting holes and the recommended mating connectors.
For thermal calculations: the
iPOS4803
Microdrives
can be assumed to generate 1 Watt (= 3.4 BTU/hour) at idle, and
up to 2.2 Watt (=7.5 BTU/hour) worst case while driving a motor.

Figure 7
Recommended spacing - horizontal mounting, worst case: non-metallic, closed box
(All dimension are expressed in mm)
The figures above shows the minimum spacing to assure proper airflow by natural convection.
If closed completely in a box, ventilation openings shall be foreseen on the top and bottom sides.
If ventilation driven by natural convection is not enough to maintain the temperature surrounding the drives, then
alternate forced cooling methods must be applied.
Remark:
In case of using a metallic box, with ventilation openings, all spacing values may be reduced substantially.
With proper ventilation, keeping the air surrounding the iPOS4803P or iPOS4803PE inside the limits indicated, the
spacing values may be reduced down to zero
