16.3 Electrical Connection

Dangerous electrical voltage! The machine may only be connected to the mains
supply and the associated checks carried out by a qualified electrician or under the
instruction and supervision of a qualified electrician!
Immediately after making the electrical connection, check the direction of rotation of
the cutter spindles. The direction of rotation is correct if the cutter spindles rotate in
the opposite direction to the feed direction. If this is not the case, change the
connection points of the phase conductors and repeat the check until the direction of
rotation of the shafts is correct.
The machine is operated with high voltage current (400 V, 3~, 50 Hz). The use of 16 A fuses is
recommended.

16.3.1 Establishing a 400V connection

To connect the machine to the electrical mains, proceed as follows:
 Use a suitable device to check that the zero connection and earthing are working properly.
 Check that the supply voltage and its frequency correspond to the specifications on the
machine nameplate. A deviation of ± 5 % from the value of the supply voltage is
permissible. For example, a machine with a working voltage of 380 V can work in the
voltage range from 370 to 400 V. The machine can be operated with a working voltage of
380 V in the voltage range from 370 to 400 V. The machine can also be operated with a
working voltage of 380 V in the voltage range from 370 to 400 V. There must be a short-
circuit fuse in the power supply of the machine!
 For the required cross-section of the supply cable, please refer to the current carrying
capacity table.
