Changing procedure of the changeover connector
1. Turn OFF the power source with the power
switch after conrming that the sewing machine
has stopped.
2. Draw out the power cord from the power plug
socket after conrming that the power switch is
turned OFF. Then wait for ve minutes or more.
3. Remove the front cover.
4. Remove four screws xing the rear cover of the
control box and slowly open the rear cover.
A. In case of using with 3-phase 200V to 240V
• Changing the changeover connector
Connect to 200V the 100/200V changeover
connector of FLT p.c.b. 1 located on the side
of the Box Side of the control box.
• Connect the crimp style terminal of AC input
cord to the power plug as shown in the gure.
B.
In case of using with single phase 100V to 120V
• Changing the changeover connector
Connect to 100V the 100/200V changeover
connector of FLT p.c.b. 1 located on the side
of the Box Side of the control box.
• Connect the crimp style terminal of AC input
cord to the power plug as shown in the gure.
(Caution) Securely perform the insulation
treatment to the red terminal which is
not used with insulation tape or the like.
(When the insulation is insufcient,
there is a danger of electric shock or
leakage current.)
C.
In case of using with single phase 200V to 240V
• Changing the changeover connector
Connect to 200V the 100/200V changeover
connector of FLT p.c.b. 1 located on the side
of the Box Side of the control box.
• Connect the crimp style terminal of AC input
cord to the power plug as shown in the gure.
(Caution) Securely perform the insulation
treatment to the red terminal which is
not used with insulation tape or the like.
(When the insulation is insufcient,
there is a danger of electric shock or
leakage current.)
5. Check that the change has been performed
without fail before closing the rear cover.
6. Be careful that the cord is not pinched between
the rear cover and the control box main unit.
Close the rear cover while pressing the lower
side of rear cover, and tighten four screws.
(3) Changing the voltage of 100 / 200V
DANGER :
To prevent personal injuries caused by electric shock hazards or abrupt start of the sewing
machine, carry out the work after turning OFF the power switch and a lapse of 5 minutes or more.
To prevent accidents caused by unaccustomed work or electric shock, request the electric expert
or engineer of our dealers when adjusting the electrical components.
It is adaptable to the voltage of single phase 100V to 120V/3-phase 200V to 240V by changing the
voltage changeover connector mounted on FLT p.c.b.
(Caution) When the changing procedure is wrong, the control box will be broken. So, be very
careful.
