* Output voltage is 3 phase and requires a motor suitable for 220-240V/3/60 input power
Mains frequency: 48....62 Hz
Max. frequency: See chapter 10.8
Min. frequency: 0 – f-max see chapter 10.9
Electrical efficiency: > 95%
Please
Note!
If the motor and control unit are assembled separately keep the
motor cable as short as possible in order to avoid electromagnetic
emissions and capacitive currents. The length may not exceed 66 m.
and a shielded cable has to be used.
Protection against: Short circuit, under- and over voltage, overheating of the electronics
(overload) and additional external protective functions via PTC (motor temperature) and
low water switch.
A mains filter is fitted to ensure interference immunity.
