Double-check the polarity of the power supply for the load before turning it on.
Observe the following precautions to protect the PC's internal components.
Output Short Protection
The output or internal circuitry might be damaged when the load connected to an
output is short-circuited, so it is recommended to install a protective fuse (0.5 to
1.0 A) in each output circuit.
Polarity of Power Supply for the Load
Double-check the polarity of the DC power supply for the load before wiring the
transistor output. If the polarity of the power supply is reversely connected, the
load will malfunction and internal components may be damaged.
