3. Electrical connection
IMPORTANT !
All work on the electrical equipment of this special sewing
machine may only be carried out by qualified electricians or
other appropriately trained persons.
The mains plug must be removed.
3.1 Rated voltage
IMPORTANT !
The mains voltage must coincide with the rated voltage
specified on the model-identification plate.
3.2 Checking the direction of rotation of the motor
IMPORTANT !
Before the special sewing machine is started it is essential
to check the direction of rotation of the motor.
Switching it on can cause damage if the direction of rotation
is incorrect.
The arrow indicates the correct direction of rotation.
–
With 3-phase drives the direction of rotation is determined by the rotatory field.
If the direction of rotation is incorrect, check whether the power supply generates a
clockwise-rotating field. If it is, 2 phases in the connecting plug must be reversed.
–
With DC drives the direction of rotation is set at the operating panel.
If the direction of rotation is incorrect it must be reversed at the operating panel.
