Each fan-coil requires a switch (IL) on the feeder line with a distance of at least 3 mm between the opening contacts, and a suitable safety fuse (F).
Warning
the EMC filters connected to frequency converters (inverters) can create leakage currents toward ground (in order to make the unit EMC
compliant, by reducing conducted emissions on power supply line). Depending on installation site, this can force the cut out of the differential safety switch.
It is recommended to install a separate differential safety switch, only for the BLDC unit, with an adjustable threshold for the cut out current.
