INSTALLATION AND WIRING
Wiring of control circuit
(4) Sink logic and source logic
In the sink logic, a signal switches ON when a current flows from the corresponding signal input terminal.
Terminal SD is common to the contact input signals. Terminal SE is common to the open collector output signals.
In the source logic, a signal switches ON when a current flows into the corresponding signal input terminal.
Terminal PC is common to the contact input signals. Terminal SE is common to the open collector output signals.
When 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
converter with the terminal 0V of the external power
supply. When using terminals PC and SD as a 24VDC
power supply, do not install an external power supply in
parallel with the converter. 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
converter with the terminal +24V of the external power
supply. When using terminals PC and SD as a 24VDC
power supply, do not install an external power supply in
parallel with the converter. Doing so may cause a
malfunction in the inverter due to undesirable currents.)
