[Wiring Precautions]
CAUTION
● Always ground the module using the included FG screw and FG strap. Failure to do so may result in
electric shock or malfunction.
● Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause fire
or failure.
●
Tighten the waterproof plugs, waterproof caps, and module mounting screws within the specified
torque range. Undertightening can cause short circuit, fire, or malfunction. Overtightening can
damage the waterproof plug, waterproof cap, and module mounting screw, resulting in short circuit or
malfunction.
CAUTION
●
The product specifications are satisfied only when all of waterproof plugs and waterproof caps are
installed with the recommended connectable devices and all screws are tightened with an appropriate
torque.
● Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can
cause a fire, failure, or malfunction.
● Clamp the cables connected to the module. If not, dangling cable may swing or inadvertently be
pulled, resulting in damage to the module or cables or malfunction due to poor contact.
● Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.
●
When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable
with connector, hold the connector part of the cable. Pulling the cable connected to the module may
result in malfunction or damage to the module or cable.
● Wiring and replacement of a module must be performed by qualified maintenance personnel with
knowledge of protection against electric shock. For wiring methods, refer to "INSTALLATION AND
WIRING" in this manual.
●
Consider fully the operating environment and input response time of CQ and Q terminals because the
module may take in noise as input when it is used in SIO mode (digital input).
