7.4.2 Three-phase alternating current motor
Warning! Danger! Electric current: Before hooking up the machine to the power supply, compare the spe-
cifications on the data plate with those of the electrical network. Only hook up the machine if the two sets
of data correspond to each other. The electrical outlet must have the appropriate socket (for a three-phase
alternating current motor, CEE).
7.4.1 Alternating-current motor
The machine‘s power cable is delivered with an open
cable end, i.e. without a plug.
The operator is responsible for fitting the machine‘s
power cable with a suitable plug in accordance with any
country’s specific regulations.
• Connect the plug to the power supply.
• Switch on and let the machine run briefly.
• While the motor is running, check its direction of
rotation.
• Should a change in the direction of rotation be
necessary, switch the two phases on the power cable.
