Mitsubishi Electric FR-A820-04750-GF Instruction Manual page 65

NOTE
• The selection example is for the ND rating. For selecting the SLD rating, LD rating, or HD rating, refer to the Instruction Manual (Detailed).
• Tighten the terminal screw to the specified torque. A screw that has been tightened too loosely can cause a short circuit or malfunction. A screw that has been
tightened too tightly can cause a short circuit or malfunction due to the unit breakage.
• Use crimp terminals with insulation sleeves to wire the power supply and motor.

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 0V terminal of the external power supply (when the sink logic is selected).
 Wiring method
• Crimp terminals commercially available (as of April 2019)
