6.3 ELECTRIC MOTOR CONECTION TO THE SYSTEM
Turn off (position 0) the motor switch before
connecting it.
6.4 EARTH CONNECTION
To protect the user from an electrical shock, the motor should be correctly connected to earth.
The motors are equipped with three cables and their respective plugs. The adequate earth box should be used to connect the motors. If
the boxes are not available, an earth adaptor should be used, before connecting the plugs.
6.5 EXTENSION CABLES
Always use extension cables with earth wire and its respective plug with earth in the female and male switches, those which will use the
male switch on the motor.
Do not use damaged or worn out cables. To avoid heavy loads on top of cables.
To determine the transversal section, follow the following procedure
6.6 PROCEDURE TO DETERMINE THE NECESSARY TRANSVERSAL SECTION IN CABLE EXTENSION
To do the following verifications and take the highest section of cable:
1.
The holmic resistance and inductive cable with the permitted voltage of 5%, cochin=0, 8 trough the frequency and
voltage curve
Entering the curve with the product: Intensity x Length=10x100=1000 Am we obtain a 4 mm section
2. The permitted heating of the cable according to VDE (minimum transversal section table required).
I. e. For 10 A, according to table for 15 A or inferior, the section is of 1 mm.
Therefore, the section chosen = 4mm, Always chose the highest transversal section of the two verifications.
