When using a single-phase AC power supply (100/200 VAC) for driving the loads of
the Relay Contact Output Module, install a safety switch for each Module. Before
inserting or removing the Relay Contact Output Module, always turn this safety switch
OFF to turn OFF the AC power supply to the Module.
Inserting or removing a Relay Contact Output Module while AC power is being
supplied may result in an electric shock at touching the power supply terminals.
