!Caution Double-check the polarity of the power supply for the load before turning it on.

Output Wiring Precautions 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.
