Note!
The failure probability of an electronic component increases with the ambient
temperature to which the component is subjected. Regarding the
serviceability and reliability, particular attention should be paid to the cooling
of the device. For every application, you should take care to keep the heating
of the device as low as possible.
ƒ We recommend to use forced−ventilated systems with "Smart Cool" fan
control to ensure sufficient heat dissipation.
The fan control monitors the internal temperature of the device and the
functioning of the fan. When a preset maximum temperature is exceeded,
the control system switches on the fan. When the fan speed falls below a
minimum speed, the control system signals a fault.
ƒ Systems with passive cooling via heatsinks should only be used if it is
guaranteed that there is always sufficient convection (e.g. by means of
external fan modules in the control cabinets or the installation of the device
in air−conditioned areas).
