The control cabinet is divided into two independent cooling zones. The inner zone, containing
the entire control electronics, is cooled by a heat exchanger or an air conditioner (optional).
In t he outer zone, the transformer (optional) and the heat sinks of t he power module and the
power supply modules are cooled directly by ambient air.
The controller is designed for an ambient temperature of max. +45 ˚C with a heat exchanger
or max. +55 ˚C with an air conditioner.
Upstream installation of filter mats causes an excessive rise in temperature and
hence a reduction in the life of the installed devices !
The heat exchanger covers on the side of the cabinet must be fitted in such a
way that the plate with the ventilation slits is located on the lower cabinet with
the ventilation slits at the bottom and therefore covered.
