The distance between the input/output cabling and the filter coil must be at least 50
mm (1.97 in.).
Cooling
￭
The filters are designed to cool by natural convection. Ensure that there is enough
fresh cooling air available and that the hot air can freely escape from the filter enclosure
or cubicle. The air space above the non-enclosed (IP00) filter and the outlet air of the
enclosed (IP22) filter is hot [up to 70 °C (158 °F) depending on the installation and
operating conditions]. Take this into account in the installation.
