> 3 x AC 480 V)

do this, the limit values of the following diagram are read at the respective
frequency and used in the formula together with the measured value.

If the total of the temperature values is greater than 10 K, the harmonics
have to be reduced by means of appropriate measures.
The supply line to the HFD must be shielded in order to avoid guided
interference emissions.
The connection cables of the mains choke have a connected voltage of
high amplitude and frequency. This can result in a possible interference of
sensitive units in the control cabinet. Therefore, the connection cables
need to be kept as short as possible and absolutely twisted (here it would
also be better to use shielded cables).
If a transformer is used, it is possible to connect HMV01.1R supply
modules to networks with mains voltages smaller than 3 x AC 380 V or
greater than 3 x AC 480 V.
Here, it is also required to use a mains choke KDxx and a combining filter
HFD just as for the direct mains connection of the HMV01.1R supply
modules.
