For continuedprotection against risk of fire, replace only with same type and rating fuse(s). To reduce the riskof electric shock, leakage-current or resistance measurements shall be carried out (exposedparts are acceptably insulated from the supply circuit) before the appliance is returned to thecustomer.The DC voltage is an actual reading measured witha high impedance type voltmeter. The measurementvalue may vary depending on the measuringinstruments used or on the product.2SA1015GR2SC2878A2SB12742SD1913TC4066BPNJM4558L2SC1846UPD75004CU-076UPC1237HA78L05ALB1641UPC1298VPST600CNote: 103SW(SW-301)/1050SW(SW-501)103SW(K) PCB/SD 98.4.24 20:41 y W 21050/103SW770620660600643643103SW/SW-301633621641632MVR401642642603603640640611SPK1630 x2612612601604601602602613613607Gx2Gx2Dx2Mx2Mx2Ex2Ex2771771771630 x2771782x2MMMVR401Dx2Cx8759759780777Jx6771773781Ax3L Ax3Ax3Ax3Hx2Lx2Nx2Nx2Jx2Jx2FFKKKK7757747727767787797P(CN201A)3P(CN804)Bx2Bx2650ABCCDDEFGHJKLMN 4x14(BLK)M4x16 5x25(BLK) 5x25(BLK) 3x20(BLK) 3x16(BLK) 3x8 3x6 3x8 3x10(BLK) 3x8(BLK) 3x10(BLK) 3x10(BLK) 3x8 3x8:N44-4014-45N35-4016-45N09-3668-05(103SW)N09-3672-05(1050SW)N44-3020-45(103SW)N62-3116-45(1050SW)N09-3669-05N89-3006-46N83-3008-46N89-3010-45N89-3008-45N34-3010-45N82-3010-45N82-3008-46N89-3008-4662562562212ACBParts with exploded numbers larger than 700 are not supplied. 103SW/SW-301/1050SW/SW-501EXPLODED VIEW (UNIT)7103SW/SW301(K) COVER( 98.4.24 20:44 yW 6PARTS LIST103SW/SW-301/1050SW/SW-50188 New PartsParts without Parts No. are not supplied.Les articles non mentionnes dans le Parts No. ne sont pas fournis.Teile ohne Parts No. werden nicht geliefert.Ref.
