CAUTION
For 400 V power supply, ensure that the neutral line (N) of the outlet and of the
extension cord is connected. If you are unsure commission an electrician to
check the connections.
If you switch on the MilkShuttle without a connected neutral wire, a protective
mechnism prevents the start up of the device. Subsequently, a fault message is
shown on the MilkShuttle‘s display (Fault 60 - No mains voltage).

Information
The protective mechanism also prevents the start up of the MilkShuttle in case of
an anti-clockwise phase sequence of the rotary field. Therefore, the fault mess-
sage
No Mains voltage (fault code 60) may be caused either by a missing neutral
wire (N) or by the anti-clockwise phase sequence of the rotary field. The phase
sequence of the rotary field may be corrected by changing the phases L2 and L3.
For that purpose, the connecting cabel (400 V) of the MilkShuttle is equipped with
an integrated phase changing switch. Inside the connector of the cable, the two
pins for the phases L2 and L3 are mounted on a round plate that can by rotated
by 180 degree. Use a screwdriver (width of blade: 6 mm) in order to rotate the
plate and subsequently change the phases L2 and L3. Please be aware of the
fact that the protective mechanism will be triggered by too high or too low mains
voltage also.
