3.4 Cooling/Air Flow Direction

The unit is cooled with an internal fan. The airflow is from the front to rear side. The fan is monitored and speed
controlled dependent on module temperature. To provide sufficient air flow, a minimum space (see item A in the
following figure) of 50 mm is required between the unit and the rear cabinet wall as well as an unobstructed
supply of air to the front of the module.
Please note:

The ambient temperature should not exceed a maximum of 45°C.

If the UNV-F module is integrated into a cabinet, the ambient temperature should not exceed a
maximum of 40°C.
