(2) Rotate the Module until it comes into contact with the Mounting Base.
(3) Fit the Module to make an electrical connection with the Module connector.
(4) Tighten the Module mounting screw on the Module.
2) Installing the Terminal Block on the Module
When installing the terminal block for the AC I/O Modules, turn OFF the AC power
supply to the I/O Modules for inputting signals and for driving load.
Installing a terminal block with the AC power being supplied to the terminal of
the external power supply for the AC I/O Modules may cause an electric shock
if the power supply terminals are touched.
When using a single-phase AC power supply (100/200 VAC) for driving loads of the
Relay Contact Output Module, turn OFF the AC power to the Modules for driving
loads before installing the terminal block for the Modules.
Installing a terminal block with the AC power being supplied to the external
power supply terminal of the Relay Contact Output Module may cause an elec-
tric shock if the power supply terminals are touched.
