Rated voltage
V AC 230 ± 10 %
Operating voltage
V AC 180 – 253
For supply voltages below the rated voltage range, a reduction of the
fan’s RPM may occur depending on the load and ambient tempera-
ture.
RCD To be installed in accordance with applicable laws and standards.
RCD 300 mA (type B) may be used in front of the supply voltage for
LPC regulated fans.
