[Wiring Precautions]
CAUTION
● Individually ground the FG and LG terminals of the programmable controller with a ground resistance
of 100 ohms or less. Failure to do so may result in electric shock or malfunction.
● Tighten the terminal block screws within the specified torque range.
Undertightening can cause short circuit, fire, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, fire, or
malfunction.
● Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
● Incorrect wiring may damage modules and external devices. Adjust a cable length and a module
position to prevent disconnection of a connector type terminal block or a cable.
● Do not solder stranded wires of a cable when connecting them to the terminal block. Doing so may
cause poor contact.
● The power supply voltage of remote slave modules may be insufficient due to a voltage drop in the
power supply line. Connect an external power supply so that the voltage of remote slave modules is
ensured.
● Do not apply the 24VDC power before wiring the entire AnyWireASLINK system. If the power is
applied before wiring, normal data transmission is not guaranteed.
● Connect a 24VDC external power supply to the device(s) in an AnyWireASLINK system.
● Do not install the control lines or communication cables together with the main circuit lines or power
cables.
Failure to do so may result in malfunction due to noise.
● Place the cables in a duct or clamp them. If not, dangling cables may swing or inadvertently be pulled,
resulting in malfunction or damage to modules or cables.
In addition, the weight of the cables may put stress on modules in an environment of strong vibrations
and shocks.
● When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable
connected to the terminal block, loosen the terminal screw. Pulling the cable connected to the module
may result in malfunction or damage to the module or cable.
