Three-phase machines
Please ensure the cable is provided with CEE 16A industrial plug/coupler 5 poles (neutral must
be connected) according to IEC60309.
Voltage Drops
Inrush currents cause short-time voltage drops. Under unfavourable power supply conditions,
other equipment may beaffected.
If the system impedance of the power supply is lower than 0.25 Ω, disturbances are unlikely
tooccur.
Sockets used for these machines shall be fused with 16 Amperes cut-out with an
inertcharacteristic.
