connection to the control circuit terminals and run them away from the main and powercircuits (including the 200V relay sequence circuit).3)Use two or more parallel micro-signal contacts or twin contacts to preventcontact faults when using contact inputs since the control circuit input signalsare micro-currents.4)Do not apply a voltage to the contact input terminals (e.g.STF)of the controlcircuit.Micro signal contactsTwin contacts5)Always apply a voltage to the fault output terminals (A.B.C)via a relay coil,lamp,etc.6)It is remended to use the cables of 0.3mm-to 0.75mm-gauge for connection to the control circuit terminals.If the cable gauge used is 1.25mm or more,the front cover may be lifted when there are mamy cables running or thecables are run improperly,resulting in a fall off of the operation panel.7)The maximum wiring length should be 30m.
