1. Spec. of the machine
1-1. Power supply specifications
Since power spec. of the machine is specified clearly as shown below, use the machine under these
conditions.
(1) Voltage,allowable voltage range: 10% of the rated voltage
(2) Power consumption (max)
Single head machine: 330 VA, 260 W
2 or more head machine: 710 VA, 420 W
(3) Frequency: 50/60 Hz
(4) Insulation resistance: 10M ohms and larger (at 500 V Megger)
1-2. Ambient noise level
The ambient noise level of the machine is less than 85 db (single head machine: less than 82 db).
Measuring environment is as the figure below.
(1) Measuring position
Higher value is adopted after measured at B and C. The height is measured at 1.6 m from the
floor.
(2) Working condition of the machine
Fabric is stretched on the border frame, and satin stitch sewing of stitch length 4 mm is executed.
(3) RPM
The maximum number of revolutions of the machine
(4) Measuring instrument
Conformity to IEC61672-1: 2002 Class 1
Since there is a danger of electric shock due to leak current,be sure to ground the earth
cable of the machine. In addition,degree of grounding should be type D or higher (grounding
resistance 100 ohms or less).
