[WIRING PRECAUTIONS]
[TEST OPERATION PRECAUTIONS]
 Tighten the terminal screws within the specified torque range.
Undertightening can cause a short circuit or misoperation.
Overtightening can cause a short circuit or misoperation due to damaged
screws or unit.

Ensure that foreign matters such as chips and wire off-cuts do not enter the
unit.
They can cause a fire, failure or misoperation.
 Be sure to fix the wires or cables by ducts or clamps when connecting them to
the unit.
Not doing so can damage the unit or cables due to dangling, moved or
accidentally pulled cables or can cause misoperation due to cable contact
fault.
 Do not install the control lines together with the communication cables, or
bring them close to each other.
Failure to do so may cause malfunctions due to noise.
 When disconnecting a communication or power supply cable from the unit, do
not pull on the cable itself.
Disconnect cables fitted with connectors by holding and pulling the cable
connector. Disconnect cables not fitted with a connector by removing the
screws from the part connected to the unit.
Pulling on a cable that is connected to the unit can cause damage to the unit
or cable, or malfunction due to cable connection faults.
 Do not output (switch on) any reserved signal among the output signals
provided from the master unit to the GOT.
Doing so can cause the PLC system to misoperate.
