There is a danger to persons and equipment, if the first commissioning of the drilling
machine is carried out by inexperienced personnel.
We do not accept any liability for damages caused by incorrectly performed
commissioning.
3.7.1 Electrical connection
Connect the electrical supply cable.
ATTENTION!
For 400V machines: Ensure that all 3 phases (L1, L2, L3) are connected correctly.
Most motor defects result of wrong connections. For instance if a motor phase is not
correctly clamped or connected to the neutral conductor (N).
Effects may be as follows:
The motor is getting hot very rapidly.
Increased motor noises.
The motor has no power.
ATTENTION!
Make sure that the direction of rotation of the drive motor is correct. The switch position
of the rotation selector switch for right-handed rotation (R) has to turn the drill spindle
clockwise. If necessary, exchange two phase connections. If your connector plug is
equipped with a phase inverter, this is done by turning it by 180°. The guarantee will
become null and void if the machine is connected incorrectly.
