Electrical Connections
The connection must be carried out by an authorised electrician!
The circuit diagrams are located behind the main control panel or (optionally) in the control cabinet.
Please observe the specified nominal voltage 400 VAC / 50 Hz (3 phases / N / PE)!
•
Ensure that the motor voltage (as indicated on the motor plate)
matches the mains voltage.
•
The supply cable is inserted through the cable gland at the bottom
of the terminal box.
•
The connection to the mains (3 phases) is made at the terminal
strip in the terminal box or optionally in the control cabinet. The 3
phases must be connected to the terminals

Note:
Some models are equipped with additional fuses in the
control panel. These protect against a possible brake short-
circuit or the optional laser cut position indicator.
Fuses used for this: 1 A (time-lag) each.
Important:
Also check the correct running direction of the bandsaw blade. If the running direction is incorrect, two phases
in the control cabinet must be reversed.
The fault loop impedance and the suitability of the overcurrent protection device must be
checked at the installation site of the machine.
The electrical wiring and connection must be carried out by a specialist in accordance with the applicable local
EVU, VDE and EN regulations.
Please note:
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.
