ATTENTION !
The nominal voltage listed on the ratings plate of the sewing drive and
the mains voltage must correspond!
An adaption to the local mains voltage occurs via the terminals 1 to 5
on the transformer 1 of the sewing drive.
At delivery, the sewing drive is set to a mains voltage of 230 V
(terminals 5 and 2).
–
Check the arrangement of the connections on the transformer of
the sewing drive.
–
Change the connections to correspond to the existing mains
voltage, if necessary.
The direct currect sewing drives used are operated with a "single
phase-alternating-voltage".
In order to avoid overloading a single phase of a threephase mains
supply when connecting multiple sewing units, the following is to be
observed:
–
The connections of the individual sewing units must be distributed
equally to the phases of the threephase mains supply.
–
The wiring for connection to a threephase mains supply is shown
in the construction circuit diagram.
