Cooling of devices
Cooling air must be able to flow unhindered through the unit (interior
and heat sink). When installing the unit in a control cabinet with natural
convection (= heat loss is dissipated to the outside via the control cabinet
walls), always provide an internal fan. If the unit is switched off due to
excessive temperature, the cooling conditions must be improved.
