4.4 Checking the nominal voltage
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.
