NOTES:
1)Followlocalcodesandregulationswhenselectingeldwires.
2)Thewiresizesmarkedwith*1intheabovetableareselectedatthemaximumcurrentoftheunitaccordingtothe
EuropeanStandard,IEC60335-1.Usethewireswhicharenotlighterthantheordinarytoughrubbersheathed
exiblecord(codedesignationH05RN-F)orordinarypolychloroprenesheathedexiblecord(codedesignation

3)Thewiresizesmarkedwith*2intheabovetableareselectedatthemaximumcurrentoftheunitaccordingtothe
wire,MLFC(FlameRetardantPolyexWire)manufacturedbyHitachiCableLtd.,Japan.
4)Useashieldedcableforthetransmittingcircuitandconnectittoground.
