Electrical connections (fig.1,2)
The electrical connections must be carried out by a qualified electrician who is able to calculate the exact
needed wire section and caliber of fuses.
- Check that the mains voltage of your machine corresponds with the voltage in your workshop.
- Open the electrical connection box (fig. 1) underneath the infeed planer table.
- Connect the three phases to the terminals marked L1, L2, L3 (fig.2).
- Connect the earthing (green-yellow) to the terminal marked with the earth symbol PE.
ATTENTION:
- Check first if the spindle runs free and if all protections are mounted before starting up the machine.
- If the rotation direction of the spindle is not correct, the leads L1, and L2 must be exchanged.
- The machine is equipped with overload protection, and should the motor be shut-off by this protection, it
is necessary to wait for a few minutes untill the overload has cooled down, and resets itself.
Turn the main switch (Q1) to position “1” in order to
put the machine under tension, and ensure that the
Star-Delta switch (S6) is set at the “Star” position.
To start up the motor push the start button (S1), and
after about 6 seconds switch over to the “Delta”
position on the Star-Delta switch (S6).
This time delay of 6 seconds is needed to let the
motor gain its full speed before switching over to
“Delta”.
When you forget to switch over from Star to “Delta”,
the motor will reach its full speed but will have no
power, and can be damaged very easily.
By pushing the emergency stop button (AU1) the
main motor is automatically stopped, and slowed
down by the automatic brake (only CE version
machines) within 10 seconds.
Make sure the brake release switch (S5) is set at
position O in order to be able to start up the machine.
On the automatic Star-Delta starter version the only
thing you need to do is to push the start button (S1),
the motor will start up automatically from Star to
Delta.
WARNING:
All fuses can be found inside the electrical cabinet,
and each time this cabinet is opened the machine
must be disconnected from the main power supply.
