The fan cartridge must be replaced every 5 years. Spare fan cartridges can be ordered from Beck-
hoff Service.
Replace the fan cartridge of the CX20x3 if:
• the fan cartridge has been used for 5 years
• or the fan speed is less than 1000 rpm.
In a CX20x3 Embedded PC the fan speed is controlled depending on the temperature.
