5 Aeration
When installing the head-end station into a rack system, it is absolutely
necessary to make sure that the ambient and operating temperatures do
neither fall below nor exceed the admissible range (-10 °C to +50 °C)
specified.
A circular aeration, for example by means of ventilators, is to be ensured
inside the rack system.
In addition, it is necessary to permanently control by means of thermo ele-
ments the ambient and operating temperature of max. 50 °C specified.
If the ambient and operating temperature inside the rack system exceeds
50 °C max., the thermo switch of the rack system must automatically dis-
connect the rack system from the power supply.
