Connecting a positive external power supply
for transistor output to terminal PC prevents
a malfunction caused by a 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 an
external power supply in parallel with the
inverter. Doing so may cause a malfunction
in the inverter due to a undesirable current.)
