Do not earth (ground). Avoidconnecting the terminal SD and 5 and the terminal SE and 5.2) Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main andpower circuits (including the 200V relay sequence circuit).3) Use two or more parallel micro-signal contacts or twin contacts toprevent a contact faults when using contact inputs since thecontrol circuit input signals are micro-currents.Micro signal contactsTwin contacts4) Do not apply a voltage to the contact input terminals (e.g. STF) of the control circuit.5) Always apply a voltage to the fault output terminals (A, B, C) via a relay coil, lamp, etc.6) It is recommended to use the cables of 0.75mm 2 gauge for connection to the control circuit terminals.If the cable gauge used is 1.25mm 2 or more, the front cover may be lifted when there are many cables running orthe cables are run improperly, resulting in an operation panel contact fault.7) The maximum wiring length should be 30m (200m for terminal FM).• Wiring of the control circuit of the 75K or moreFor wiring of the control circuit of the 75K or more, separate away from wiring of the main circuit.Make cuts in rubber bush of the inverter side and lead wires.Rubber bush(view from the inside)Make cuts along the lines inside witha cutter knife and such.24
