Wiring Of Control Circuit - Mitsubishi Electric FR-A820-00046 (0.4K) Instruction Manual

• When using an external power supply for transistor output
Sink logic
Use terminal PC as a common terminal, and perform wiring as
follows. (Do not connect terminal SD on the inverter with the
terminal of 0 V for the external power supply. When using
terminals PC-SD as a 24 VDC power supply, do not install an
external power supply in parallel with the inverter. Doing so
may cause a malfunction in the inverter due to undesirable
currents.)

Wiring of control circuit

 Control circuit terminal layout
• Recommended cable gauge: 0.3 to 0.75 mm
AM 5 10E 10 SE SE
*1 This terminal operates as terminal FM for the type FM inverter. For the type CA inverter, the terminal operates as terminal CA.
 Wiring method
 Power supply connection
For the control circuit wiring, strip off the sheath of a cable, and use it with a blade terminal. For a single wire, strip off the sheath
of the wire and apply directly.
Insert the blade terminal or the single wire into a socket of the terminal.
1.
Strip off the sheath for the below length. If the length of the sheath peeled is too long, a short circuit may occur with
neighboring wires. If the length is too short, wires might come off.
Wire the stripped cable after twisting it to prevent it from becoming loose. In addition, do not solder it.
