Max. current consumption at:
Shaft height
230 V/50 Hz 1AC (±10%) 230 V/60 Hz 1AC (+5%/-10%)
63 < 0.1 A < 0.1 A
80 to 100 0.40 A 0.45 A
Note the following information regarding connections:
● Only use cables that comply with the relevant installation regulations regarding voltage,
current, insulation material, and load-carrying capacity.
● Before connecting the device, make sure that the line voltage matches the device
voltage.
● Check whether the data on the fan rating plate matches the connection data.
● Connection cables must not be subject to excessive tensile stress.
● Connect the protective conductor (PE).
● Make sure that the fan is switched on when the motor is running.
