a）Checkthelinecolorandterminalnumberwhenconnectingwires.
Whileanovercurrentprotectioncircuitfortheoutputtransistorandaprotection
circuitforerroneouswiring,usingdiodesforpreventingreverseconnection,are
implemented,thesedonotprotectagainstallincorrectwiring.Incorrectwiringcan
resultinmalfunction,failure,ordamagetothesensor.Checktheinstructionmanual
forlinecolorsandterminalnumbersinordertoensurecorrectwiring.
b）Ensurethatwiresareproperlyinsulated.
Checkthatwiresdonotcomeintocontactwithothercircuits,thatnoground
faultsoccur,andthattheinsulatorbetweenterminalsisnotdefective.
Otherwise,overcurrentmayflowintothesensor,causingdamage.
a）Observethefollowingitemswhenwiring:
・Whenusingaswitchingregulatorforthepowersupply,
groundtheF.G.(frameground).
・Avoidusinginthetransientstate,1safterpoweristurnedON.
・Takespecialcaretopreventloadshort-circuitsorincorrectwiring.
Theprotectivecircuitisactivated.
・M12connectorpinsarearrangedasshowninlowerfigure.
Takespecialcaretopreventincorrectwiring.
・Whenusingaloadwithalargerushcurrent,suchasamotor,theprotectioncircuit
willactivate.Inthiscase,usearelay.
・Ifthereisadevice(motor,welder)thatgeneratesalargesurgenearthisproduct,
insertasurgesuppressor,suchasavaristor,atthesourceofthesurge.
・Ifthisproduct'sleadwireiswiredwiththedrivecableorpowercable,
itisaffectedbysurgeandnoisedeterioratingordamagingthesensorelement
intheswitch.Useseparatewiring.
b）Keepunusedwiresfromcomingintocontactwithotherwires.
c）Donotapplyloadtothecable.Itmaycausebreakageorbreakage.
Also,Usecabletiestofixthecableinplace.
d）DonotbindthesensorcabletogetherwithACpowerwiring.
