Mitsubishi FR-E 500 Instruction Manual page 38

• When using an external power supply for transistor output, use terminal PC as a
common to prevent misoperation caused by undesirable current.
(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 the
power supply in parallel outside the inverter. Doing so may cause misoperation due
to undesirable 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.
