3.9 Electrical connection
WARNING!
The three-phase electrical connection may only be performed by an electrician or under
the guidance and supervision of an electrician.
CAUTION!
Arrange the machine's connection cable in such a way that it will not cause a tripping
hazard.
CAUTION!
When connected to a ~60Hz network, the speed increases 1.2 times. Make sure that your
lathe chuck can be used for this increased speed.
ATTENTION!
Ensure that all 3 phases (L1, L2, L3) and the ground wire are connected correctly.
The neutral conductor (N) of its power supply is not connected.
ATTENTION!
Observe the rotating field!
Please check that the type of current, voltage and protection fuse correspond to the values
specified. A protective earth ground wire connection must be available.

Mains fuse 16 A.
ATTENTION!
Make sure that the direction of rotation of the drive motor and cooling lubricant pump is
correct. If the rotational direction switch is switched to the down position, the lathe
spindle must rotate anticlockwise. If necessary, two phase connectors at the three phase
current switch or at the connection in the control cabinet must be exchanged. The
guarantee will become null and void if the machine is connected incorrectly.
3.10 Start and stop spindle rotation
Switch the rotation lever depending on the desired direction of rotation up or down. Switch in
the neutral position to stop the machine.
3.11 Warming up the machine
ATTENTION!
If the machine and in particular the lathe spindle are immediately operated at maximum
load when cold, this may result in damages.
If the machine is cold, e.g. directly after having transported the machine, it should be
warmed up at a spindle speed of only 500 1/min for the first 30 minutes.
