7 Frequency Converter Mounting
7.1 Installation Conditions
The frequency converter must be vertically installed.
If one frequency converter is arranged above another, make sure the upper limit
of air temperature into the inlet is not exceeded (see
on page
24). An air guide is recommended between the frequency converters to
prevent the rising hot air being drawn into the upper frequency converter if the
upper limit of air temperature is exceeded.
