Control circuit terminal
 Wiring precautions
• It is recommended to use a cable of 0.3 to 0.75 mm
• The wiring length should be 30 m (200 m for the terminal FM) at the maximum.
• Use two or more parallel micro-signal contacts or twin contacts to prevent contact faults when using contact inputs since
the control circuit input signals are micro-currents.
• To suppress EMI, use shielded or twisted cables for the control circuit terminals and run them away from the main and
power circuits (including the 200 V relay sequence circuit). For the cables connected to the control circuit terminals,
connect their shields to the common terminal of the connected control circuit terminal. When connecting an external
power supply to the terminal PC, however, connect the shield of the power supply cable to the negative side of the external power supply. Do not directly earth
(ground) the shield to the enclosure, etc.
• Always apply a voltage to the fault output terminals (A1, B1, C1, A2, B2, C2) via a relay coil, lamp, etc.
• Do not connect any terminal SD on the inverter and the 0 V terminal of the external power supply (when the sink logic is selected).
• When a relay coil is connected to the output terminals, use one with a surge absorbing function (reflux diode). When the voltage application direction is
incorrect, the inverter will be damaged. Pay attention to the diode direction or other precautions to avoid incorrect wiring.
