Wiring Of Control Circuit - Mitsubishi Electric 800 Series 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.)

Source logic
Use terminal SD as a common terminal, and perform wiring as
follows. (Do not connect terminal PC on the inverter with the
terminal of +24 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.)
