Section 7 Additional Installation Tips
Ambient Temperature
an electrolytic capacitor is cut in half with an 8-10 °C increase in temperature. A
15-20 °C temperature increase results in a quarter of the lifespan etc.
Rittal has a good program for estimating the anticipated average temperature in the
cabinet as well as a large program for controlling the temperature in the device
cabinet.
An enamel-coated steel cabinet has a radiant heat value of 5.5 W/m
2
and degrees C.
Installing a fan inside the cabinet evens out the temperature, while moving air
provides considerably better cooling than still air.
Install the fan so that it sits in a cooler area and blows cold air against the operator
panel. If the fan is mounted at the top and sucks warm air upwards, the ambient
temperature of the fan becomes higher, resulting in a shorter lifespan.
An approximate value of the net power consumption for the operator panel can be
calculated by multiplying the supply voltage with the current drawn by the operator
panel. This is assuming that all supplied power is transformed to heat.
