6.4.2 AC Output Modules
2) Protective Fuses
CAUTION
3) Connecting Contacts to an Inductive Load
CAUTION
If using an Output Module, connect a fuse that complies with the load specifications in
series with the load.
A protective fuse built into the following Output Modules does not protect the
output element. If a fuse is not connected, a fire or damage to the device or out-
put circuits may occur if the load is short-circuited or the circuit overload.
The built-in fuse protects the Output Module from damage that may occur in the fol-
lowing cases:
• When over-voltage is applied to the load driving power supply terminal of the
Output Module.
• When foreign matter such as chips are in the Output Module and short-circuiting
the internal circuits.
Not installing external fuses may cause fire and damage to the output circuit and the
Module if an over-voltage or short-circuit occurs.

If connecting an inductive load to the AC Output Module, connect the surge absorber
in parallel with the inductive load to prevent surge voltage.
Failure to connect a surge absorber may result in damage to the AC Output
Module.
