DigiPoS PowerPoS & Millennium Technical Manual
Ventilation Requirements
Cavity Size
If the DigiPoS is to be located in a cavity, i.e. under the counter, the cavity dimensions
must be a minimum of 380mm long by 400mm wide by 120mm deep (excluding the
external PSU). A diagrammatic representation is as follows:
120mm
400mm
Although this is the required space, the DigiPoS MUST be located centrally to prevent the
airflow from being disrupted through the ventilation holes in the sides of the case.
Enclosed Spaces
If the DigiPoS is to be located in an enclosed space, i.e. in a closed box or cabinet, there
must be sufficient airflow into and out of the enclosed space. Using the above cavity
space as an example, forced airflow would have to be fitted to prevent the DigiPoS from
overheating. As a general rule, the PowerPoS & Millennium require an airflow exchange
rate of a minimum of 25 CFM (Cubic Feet per Minute) excluding PSU or 30 CFM including
PSU when in an enclosed space.
The recommended location for these fans is as follows:

External PSU
PC-PoS recommends that the external PSU for the PowerPoS & the Millennium are not
situated in the same space as the DigiPoS to minimise heat build up in enclosed spaces.
If this is unavoidable, forced air ventilation must
be installed to provide adequate
ventilation for the DigiPoS & PSU heat dissipation devices.
