• 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 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.)
