ƒ For polluted cooling air (dust, lints, greases, aggressive gases):
– Implement adequate counter measures, e. g. separate routing of ait flow, regular
cleaning, etc.
ƒ Mounting clearances!
– Observe unobstructed influx of the cooling air and emission of the exhaust air!
– Observe a free space of 50 mm above and below as well as to the sides.
– In case of high load and bad heat dissipation, the controller lowers the drive
power, or possibly switches off.
