Recommended residual-current device
The appliance is fitted with a variable frequency drive (FC) with built-in EMC filter and an EMC line
filter. These devices may result in a leakage current of more than 3.5 mA.
Use a suitable RCD for the rated voltage:
Rated voltage
3~ 200 V 50/60 Hz
3~ 220-240V 50/60Hz
3N~ 380-415V 50/60Hz
Recommended residual-current device
Type A
Optional residual-current device
Type B
Properties of the residual-current device
The residual-current device (RCD) must have the following properties:
■
Filter for filtering out RF currents
■
"Time delayed" trip characteristic for RCD devices with trip threshold >30 mA:
prevents RCD being tripped by charging currents of capacitors and parasitic capacitances when
appliance is switched on.
■
"Leakage current protection, type SI" trip characteristic for RCD devices with trip threshold
£
30 mA:
insensitive to nuisance tripping.
Mains supply connection
The power cord must be an oil-resistant, sheathed and flexible cable in accordance with IEC 60245
(e.g. H05RN-F, H07RN-F). A maximum cable length of 5 m is recommended.
The appliance does not need to be connected in a specific phase sequence or a specific direction of
rotation.
