3.3 ELECTRICAL CONNECTION - START UP
Electrical installation should be carried out by competent, qualified personnel.
The mains connection should be made using the terminal box as shown in FIG. 9 pos. E.
Ensure that the mains supply corresponds with that of the machine, use cables of a section suitable for the power of the motor. For a
supply tension of 400 V the minimum section recommended is 2.5 mm, including the earth wire.
For a mains supply of 230 V or a power rating greater than 15 A it will be necessary to increase the section
of the connecting cables .
Connect the phase wires to the terminals R- S - T (L1 - L2 - L3) and the earth wire to the earth terminal.
On initial start-up check the direction of rotation, if it is incorrect then invert the two phase wires (for machines with 3 phase supply).
Direction of rotation of machines with single-phase supply is pre-determined during production .
On completion of the installation check that the terminal box is closed correctly and that the plug points are locked.
Starting the machine :
For the models 352SB, 401S, 440R, 501S, 581S, 681S, 781S:
Turn the isolator switch located at the rear of the machines FIG. 9 pos. E, to position "1", the white indicator light on the front panel
shows that there is electrical power: turn the starter switch "M" to position "1" to start-up the machine (FIG. 10).
To stop the machine press the stop button. Ensure before start uo the brake switch is in the on position (the machine will not start
with brake in the off postion)
PLEASE NOTE: 352SB 3 phase (2 speed) model the speed selector switch must be set at zero to switch the machine on. It is then
started by turning the speed selection switch to speed 1 or 2.
For the model 941S:
Turn isolator switch "E" (FIG. 9) located at the rear of the machine to position "1", the white indicator light on the front panel shows
that there is electrical power. Turn switch "M" into position "1". Now turn and hold switch "T" (FIG. 11) to position "Y" until the
machine reaches normal running speed, then turn to position "∆". Average time to reach normal speed: 4-8 seconds. To switch off,
turn Switch "T" back to "O".
In case of emergency shut-off or power failure, it is necessary to turn the starter control (switch "T") back to "O" and repeat the start-
up procedure.
IMPORTANT: machines will not start with the doors open and will automatically stop if doors are opened during operation.

3.4 DUST EXTRACTION
The machine must be connected to
an adequate dust extraction system.
Diameter of the extraction tubes and
connecting positions on the machines are
indicated in FIG. 12 and FIG. 13.
Airspeed: The minimum advisable
air speed is 20 mt/sec for wood with
humidity less than 12%. For wood
with an humidity greater than 12% it is
advisable to increase the air speed to
25-28mt/sec.
Capacity: Approx 600mt/h for tube diam.
100mm, 800m /h for tube diam 120mm,
1100mt/h for tube diam 140mm.
