The earth (grounding) cable 1 is included in the machine's accessory
pack.
The earth cable 1 conducts static charges from the machine head via
the motor foot to the earth.
–
Connect the earth cable 1 to the tab connector 2 (connector is
already screwed on to the machine head). Then route the cable
3
through the cable duct to the motor foot.
–
Screw the earth cable 1 to the motor foot or control unit box using
screw 3.
–
The earth cable 1 should also be fastened under the table plate
with nail clips.
Note:
For sewing machines with a sewing drive integrated into the machine
head, there is no need to establish equipotential bonding since this is
implemented with the attached motor.
Caution!
Make sure that the earth cable 1 does not come into
contact with the V-belt.
