CAUTION
Do not apply voltages to the connectors other than voltages indicated in this manual. Failure to
observe this could cause the devices to rupture or damage, etc.
Incorrect connections could cause the devices to damage. Connect the cable to the designated
connector.
Do not connect or disconnect the connection cables between each unit while the power is ON.

(Note 1)
When using an inductive load such as relay, always connect a diode (withstand voltage 100V or more,
100mA or more) in parallel to the load.
(Note 2)
When using a capacitive load such as lamp, always connect a protective resistor (R=150
Ω
) serially to the
load to suppress rush currents. (Make sure that the current, including the instantaneous current, is less
than the above tolerable current.)
