Inverter doesn’t block the current flowing into itself when it is not powered. This may cause
the closed circuit when two or more inverters are connected to common I/O wiring as
shown below to result in unexpected turning the on the input. This may lead to
dangerous situation. To avoid this closed circuit, please put the diode (rated:50V/0.1A)
in the path as described below.
