NOTE !

The nominal voltage, stated on the type plate. Should agree with the

local voltage!

Use the terminals 1 to 5 on the transformer 1 of the sewing unit-

for adapting to the local voltage.

At the moment of delivery, the sewing motor is set to a mains voltage

of 230 V ( terminals 5 and 2 ).

–

Check the arrangement of connections on the transformer of the

sewing motor.

–

If necessary, change the connections according to the local

voltage.

The direct current sewing drives are operated by a single-phase a.c.

current.

In order to avoid an overload of a single phase when connecting

several machines to a threephase current, -

please note the following:

–

The connections of the single machines must be evenly distributed

onto the phases of the threephase line.

–

The wiring of the connection to the threephase line is shown in the

wiring diagram.
