Using an external power supply
●
Source logic type
When using an external power supply for transistor output, use terminal SD as a common to
prevent misoperation caused by undesirable current.
●
Sink logic type
Use terminal PC as a common terminal to prevent a malfunction caused by undesirable current.
(Do not connect terminal SD of the inverter with terminal 0 V of the external power supply. When
using terminals PC-SD as a 24 V DC power supply, do not install a power supply in parallel in the
outside of the inverter. Doing so may cause a malfunction due to undesirable current.)
