Mitsubishi Electric FR-E500 Instruction Manual page 39

• When using an external power supply for transistor output, use terminal PC as a
common to prevent misoperation caused by leakage current.
(Do not connect terminal SD of the inverter with terminal 0V of the external power
supply. When terminals PC-SD are used as a 24VDC power supply, you cannot
prevent misoperation caused by leakage current.)
3) Source logic type
• In this 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 common to the
open collector output signals.
