Spec. of the machine 222 Chapter 11 QS07 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: 250 VA, 150 W 2 or more head machine: 2.0 kVA, 1.4 kW (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). ! WARNING 1.0 m 1.5 m C B Wall A 5 m or more 5 m or more 5 m or more 5 m or more A: Position of needle location
