zWhen using an external power supply for transistor output
• Sink logic type
Use terminal PC as a common
terminal, and perform wiring as shown
below. (Do not connect terminal SD of
the inverter with terminal 0V of the
external power supply. When using
terminals PC-SD as a 24VDC 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 type
Use terminal SD as a common
terminal, and perform wiring as shown
below. (Do not connect terminal PC of
the inverter with terminal +24V of the
external power supply. When using
terminals PC-SD as a 24VDC 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.)
