(Do not connect terminal SD ofthe inverter with terminal 0V of the external powersupply. When using terminals PC-SD as a 24VDCpower supply, do not install a power supply in parallel inthe outside of the inverter. Doing so may cause amalfunction due to undesirable current.)QY40P type transistoroutput unitConstantvoltagecircuitTB1TB2 STRTB17STFCurrent flowPCTB1824VDC SDInverter24VDC(SD)⋅24VDCCurrent flowSource logic typeUse terminal SD as a common terminal, and performwiring as shown below.
