10.2 General ambient conditions
The following conditions must be taken into account when installing a frequency converter:
Shocks and vibrations
The frequency converter must not be dropped, exposed to sudden shocks or installed in
surroundings where it might be exposed to regular vibrations.
Air pollution/water
The frequency converter must not be installed in areas where there are corrosive gases and
air pollution; however, it can be exposed to dust and splashwater (degree of protection
IP65).
Installation and cooling
Make sure that convection can take place freely in front of the frequency converter. In this
area there must be no devices which could obstruct or affect the convection.
A clearance of 35 mm must be kept above and below the components of the frequency
converter from other devices or components in order to ensure that convection can take
place unhindered.
