Electrical Connections
The connection must be carried out by an authorised electrician!
The electrical circuit diagrams are located in the control cabinet on the right-hand side of the machine.
Please observe the specified nominal voltage 400 VAC / 50 Hz (3 phases / N / PE)!
• The supply cable is inserted through the cable gland at the bottom of the
main switch housing.
• The connection to the mains (3 phases) is made at the main switch in the
main switch housing. The 3 phases are to be connected to the terminals
"L1", "L2" and "L3".
• The protective earth wire (yellow/green) is to be connected to the termi-
nal marked "PE".
• With the option "variable feed rate", the neutral conductor must also be
connected to the terminal marked "N" on the main switch. Please note:
"N" is loaded in this case!
• Then close the cable gland again so that it is dust-tight.
• Observe the direction of rotation of the cutter head as well as the move-
ment direction of the feed.
If the direction of rotation of the cutter resp. the movement direction of the feed is not
correct, two outer conductors must be swapped at the corresponding motor connection.
The cover may not be open! Risk of injury from rotating parts!
Only if the connection is carried out by an authorised electrician can a guarantee be given for the motor. In the
event of a complaint, the electrician must confirm in writing that he has connected the machine in accordance
with the regulations.
