Connecting the special sewing machine to the low voltage supply

The sewing machine drive is supplied from the low voltage power
supply.
Caution!
Work on the electrical equipment of the sewing machine may only be
carried out by qualified electricians or other appropriately trained
persons.
It is strictly required to carefully read the drive instructions provided by
the manufacturer!
The power cord must always be disconnected while working on the
electrical equipment!
Caution!
The voltage of the mains must comply with the voltage specified on the
ratings plate!
The following items are part of the low voltage system:
–
Connection cable
–
Sewing drive
–
Sewing light transformer (optional equipment)
–
Cable
When the sewing machine is delivered, some of these items are
included in the "drive set" while other items are included in the "motor
part set".
The connection to the low voltage supply should be carried out
according to the circuit diagram included in the "motor part set".
Caution Danger of Injury!
The drive may only be operated with a protective earth conductor.
It must be connected to protect personnel from fire or electric shock, in
compliance with accident prevention regulations.
It is unsafe to operate the sewing machine while the protective earth is
disconnected. This protection may not be cancelled out in any way (for
example, by the use of an extension cable without grounding/earth).
